Hello to all...

..Major Hurricane Earl Track Shifted a Bit Westward in 5 AM Advisory package. Hurricane Watches expanded from Plymouth Westport, Massachusetts. Inland Tropical Storm Watches issued for Bristol and Plymouth Counties..
..Major Hurricane Earl Threatens Southern New England with the potential for sustained tropical storm force winds particularly in Southeast New England but much of Eastern New England could be affected with tropical storm force winds in gusts and the potential for a period of hurricane force winds particularly over portions of Cape Cod and Nantucket Island. A further westward trend could bring hurricane force conditions as far north as Plymouth and and as far west as Westport, Massachusetts..
..A Hurricane Watch is in effect from Plymouth to Westport Massachusetts including Nantucket and Martha's Vineyard Islands..
..A Tropical Storm Watch is in effect from the Mouth of the Merrimack River Massachusetts to Plymouth Massachusetts and from Sandy Hook New Jersey to Woods Hole Massachusetts..
..Track guidance is gradually coalesing between the 40 North/70 West benchmark and Buzzards Bay Massachusetts. Deviations in the forecast track could mean greater or lesser impact to Southern New England and there is still is up to 100-125 nautical mile error in the forecast track at this stage. Southern New England is now in the '3-day cone' regarding Earl's eventual track..
..All Emergency Management and Public Safety personnel, Amateur Radio and Non-Amateur Radio SKYWARN Spotters should continue to keep high situational awareness regarding the track and intensity of major Hurricane Earl. People should review hurricane/tropical storm safety tips now as a precaution..
..VoIP Hurricane Net and Hurricane Watch Net along with WX4NHC, Amateur Radio Station at the National Hurricane Center will activate at 4 PM Thursday Afternoon for Earl's closest path to the Outer Banks and Eastern North Carolina, Eastern Virginia and the Delmarva Peninsula..
..SKYWARN Activation with Ops at NWS Taunton are likely Friday Morning into Saturday Morning based on the current track and intensity of Hurricane Earl. Massachusetts State EOC RACES and MEMA RACES Regional Office activation is slated to occur Friday Morning. Eastern Massachusetts ARES will be placed on stand-by starting at 7 AM ET Friday Morning lasting through 7 PM Saturday Evening..

Models are gradually coalesing on a solution putting Earl anywhere from around the 40 North/70 West Benchmark and then east of Cape Cod to a track over Cape Cod and between Martha's Vineyard and Nantucket Islands. There remain some eastward and westward outliers but the general consensus of models is between those two areas. There remains a 100-125 nautical mile error which can still result in greater or lesser impact over the region. A continued westward trend has been noted with computer models with tracks anywhere from Buzzards Bay to the 40 North/70 West benchmark. This needs to be closely monitored for a more westward trend and greater impact to the region. It has resulted in an expansion of Hurricane Watches and they now cover from Plymouth to Westport, Massachusetts.

The following is a rough estimation of impacts over the Tropical Storm and Hurricane Watch areas based on the current track and intensity of the hurricane and its extremely large size. This could change based on hurricane intensity and track of the system:

Hurricane Watch Area (Sagamore Beach to Woods Hole Cape Cod, Martha's Vinyeard and Nantucket Islands):

This region will see high-end sustained tropical storm force winds with hurricane force wind gusts. It is now looking more likely that the Outer Cape and particularly Nantucket Island would have the potential to also see sustained hurricane force winds and gusts pending the eventual track of Earl. Rainfall will be very heavy with the potential for a swath of 3-6" rainfall with isolated higher amounts. Storm surge will be most prevelant over north and east facing beaches with a 1-3 foot surge affected. Locations in Provincetown and Wellfleet could see greater impact if the track is a bit closer and the storm surge may occur some time after storm passage depending on that track.

Hurricane Watch Area (Plymouth to Sagamore Beach and from Westport Massachusetts to Sagamore Beach Massachusetts)

This area could see sustained winds of 35-45 MPH with gusts to 60-70 MPH and possibly slightly higher gusts. The Hurricane Watch has been issued to guard against a more westward solution towards Buzzards Bay. If that were to verify, hurricane force conditions sustained or in gusts may occur but the current solution would keep most of that to the east of this region. Rainfall in this area is likely to be 3-6" with isolated higher amounts along the coast and inland Southern Bristol and Southern Plymouth Counties of Massachusetts. Storm surge over the south coast isn't expected to be a major factor due to the wind direction but a 1-2 foot surge could occur over the Plymouth area depending on the track of Earl.

Tropical Storm Watch Area (Mouth of Merrimack River Massachusetts to Plymouth Massachusetts and South Coastal Rhode Island including the Tropical Storm Inland Wind Watch for Northern Bristol and North-Central Plymouth Counties):

In this area, sustained winds of 20-30 MPH with gusts of 40-50 MPH are possible depending on the track of Earl with the exception of inland Bristol and Plymouth Counties which could see sustained winds of 30-40 MPH with gusts to 60-65 MPH. Across the remainder of Rhode Island and Eastern Massachusetts inland of the TS Watch winds will drop off a bit with rainfall of 2-4" with isolated higher amounts possible but if a further west track were to materialize more wind could occur in portions of Rhode Island and Eastern Massachusetts. It is noted that portions of Worcester County and Northeast Connecticut could see 1-3" of rainfall.

There remains 3 factors that will further determine the track of Major Hurricane Earl that are still being scrutinized by the weather models are as follows:

1.) The strength and location of the Great Lakes trough and its interaction with Hurricane Earl
The strength and location of the Great Lakes trough and its interaction with Hurricane Earl will be critical. If the trough's location is further west or not amplifying and interacting with Hurricane Earl, this would allow a closer to the coast track and more direct impact. If it amplifies and can interact with Earl, it would result in a greater push to the east.

2.) The sharpness and locations of the turns Earl will make
Depending on the sharpness and locations of Earl turns will determine the interaction with the Great Lakes trough and his eventual movement. This will be especially true as Earl approaches the Outer Banks of North Carolina on Thursday and this will be a critical time in the track and impact of Hurricane Earl on Southern New England.

3.) Intensity of Hurricane Earl as it moves up the coast
The intensity of Hurricane Earl will now be controlled by eyewall replacement cycles and other shorter-term phenomenon that cannot be fully predicted. Earl has gone through a significant intensification process and has grown in size. Unlike past hurricanes that have been much weaker as they approached New England, water temperatures are above normal and Earl is a very powerful and large hurricane. This is likely to result in greater impact from Earl then most tropical systems approaching New England because of its large size and intensity. In addition, the intensity of Earl may affect the movement of the system.

Swells and rip currents will become a very serious concern as Earl tracks closer to the region on Thursday extending through the Labor Day Holiday Weekend after Earl passes. There have been many times where offshore tropical systems have caused injuries or fatalities on the water from the surf and rip currents so folks swimming at area beaches over the next several days with the hot weather expected are advise to heed the advice of lifeguards and monitor NWS Taunton products for high surf advisory information. See link below for the the surf zone forecasts for more information and if High Surf Advisories are posted, that link will be posted and updated here:

NWS Taunton Surf Zone Forecast Information:
http://kamala.cod.edu/ma/latest.fzus51.KBOX.html

All Emergency Management and Public Safety personnel, Amateur Radio and Non-Amateur Radio SKYWARN Spotters should continue to keep high situational awareness regarding the track and intensity of major Hurricane Earl. People should now be reviewing their preparedness measures for tropical storm/hurricane force conditions as a precaution in inland areas and as a requirement along the coast in the Tropical Storm and Hurricane Watch areas. This information has been provided via the Hurricane Preparedness Week Public Information Statements of Safety Tips and an updated Public Information Statement of Safety Tips as well as a Tropical Terminology Public Information Statement listed via the links below:

http://kamala.cod.edu/ma/latest.nous41.KBOX.html
http://kamala.cod.edu/offs/KBOX/1009011537.nous41.html

The VoIP Hurricane Net and Hurricane Watch Net along with WX4NHC, Amateur Radio Station at the National Hurricane Center will activate at 4 PM Thursday Afternoon for Earl's closest path to the Outer Banks and Eastern North Carolina, Eastern Virginia and the Delmarva Peninsula. These nets will likely activate again Friday for Earl's closest path to New England. It is noted that the VoIP Hurricane Net will merge into one large command net with New England Echolink/IRLP operations as it approaches New England. Please see these web sites for information on the Hurricane Nets and the Amateur Radio Station at the National Hurricane Center, WX4NHC:

From a spotting perspective, we will be looking for any and all reports per the SKYWARN reporting criteria. We'll also be looking for lowest barometric pressure readings across Southeast New England. Also, pictures of damage and incidents as they occur in near real-time or shortly after release will be very helpful to media, emergency manamgement, the National Hurricane Center and the NWS Taunton Forecast Office. A reminder on SKYWARN Net frequencies for the region via the link below:

http://www.wx1box.org/node/37

SKYWARN Activation with Ops at NWS Taunton are likely Friday Morning into Saturday Morning based on the current track and intensity of Hurricane Earl. Massachusetts State EOC RACES and MEMA RACES Regional Office activation is slated to occur Friday Morning. Eastern Massachusetts ARES will be placed on stand-by starting at 7 AM ET Friday Morning lasting through 7 PM Saturday Evening.

In the "Because we can" Dept.

An Android app, WiFi File Explorer, allows you to set up a web server on your Droid phone. You can then download or upload files via a web browser.

I want to do what's right

The sign in the men's room at the college gives clear instructions on how to wash your hands to prevent the spread of diseases and/or cooties.

But, the follow-through is a bit lacking.

A mighty wind in Templeton

As you drive from Templeton Center on Baldwinville Road to, um, Baldwinville, you come around a corner and see this:

Even if you're expecting it, it's still a surprise, as though something from War of the Worlds has jumped into the woods.
It's the new windmill located behind Narragansett Regional High School. The town's municipal light department has just brought the generator online. You can read more here: Templeton wind turbine gets cracking.


Although Wormtown Fleet is supposed to be covering turf that Jeff would have blogged during his taxi rides around Worcester, we're taking a bit of license because, well, because we can.

Hello to all...

The National Weather Service in Taunton issued a Public Information Statement on knowing your Tropical Cyclone Terminology. Please see the information listed below:

PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE TAUNTON MA
1137 AM EDT WED SEP 1 2010

...KNOW YOUR TROPICAL CYCLONE TERMINOLOGY...

TROPICAL STORMS AND HURRICANES ARE NO STRANGERS TO SOUTHERN NEW
ENGLAND.  SINCE 1900...A TOTAL OF 53 TROPICAL SYSTEMS HAVE
IMPACTED OUR REGION IN ONE WAY OR ANOTHER.  THERE HAVE BEEN 24
HURRICANES AND 29 TROPICAL STORMS.  AN ADDITIONAL 26 POST-
TROPICAL SYSTEMS HAVE ALSO IMPACTED OUR REGION.  ANY HURRICANE
OR TROPICAL STORM IS CAPABLE OF BRINGING A COMBINATION OF HIGH
WINDS...LARGE STORM SURGES AND EVEN INLAND FLOODING ON OCCASION.

TO BETTER PREPARE YOURSELF FOR A POSSIBLE TROPICAL CYCLONE
STRIKE...YOU SHOULD BE FAMILIAR WITH DIFFERENT TERMS THAN MAY BE
USED.  THIS STATEMENT WILL BRIEFLY DEFINE THESE TERMS RELATED TO
TROPICAL CYCLONES.

TROPICAL CYCLONE...THIS IS THE GENERIC TERM USED TO DESCRIBE
BOTH TROPICAL STORMS AND HURRICANES.

TROPICAL DEPRESSION...THIS IS A TROPICAL CYCLONE IN WHICH THE
MAXIMUM SUSTAINED SURFACE WINDS ARE 38 MPH /33 KT/ OR LESS.
THOUGH THE WIND SPEEDS ARE SIGNIFICANTLY LESS THAN THOSE IN A
HURRICANE...TROPICAL DEPRESSIONS ARE CAPABLE OF PRODUCING
TREMENDOUS RAINFALL AMOUNTS.  DURING THE WEEK OF JULY 3RD TO
JULY 7TH IN 1994...TROPICAL STORM ALBERTO MOVED INLAND AND
WEAKENED TO A TROPICAL DEPRESSION. IT THEN MOVED INTO GEORGIA
AND PRODUCED UP TO 28 INCHES OF RAINFALL.  THIS RESULTED IN
CATASTROPHIC RIVER AND SMALL STREAM FLOODING.

TROPICAL STORM...THIS IS A TROPICAL CYCLONE IN WHICH THE MAXIMUM
SUSTAINED SURFACE WINDS ARE 39 TO 73 MPH /34 TO 63 KT/.  THESE
SYSTEMS ARE ALSO INTENSE RAINFALL PRODUCERS...BUT OFTEN CAUSE
ENOUGH WIND AND WAVES TO RESULT IN SOME BEACH EROSION AND MINOR
BOAT DAMAGE.  A TROPICAL CYCLONE IS GIVEN A NAME ONCE IT REACHES
THIS STRENGTH.

HURRICANE...THIS IS A TROPICAL CYCLONE IN WHICH THE MAXIMUM
SUSTAINED SURFACE WINDS ARE 74 MPH /64 KT/ OR GREATER.  THIS IS
THE WORST AND STRONGEST OF ALL TROPICAL CYCLONES.  HURRICANES
PRODUCE TORRENTIAL RAINFALL...LARGE STORM SURGES AND HIGH WAVES
IN ADDITION TO THE STRONG WINDS.  NEW ENGLAND WAS THE RECIPIENT
OF ONE OF THE WORST HURRICANES EVER...WHEN THE GREAT NEW ENGLAND
HURRICANE OF 1938 CAME CRASHING ASHORE ON SEPTEMBER 21ST.

POST-TROPICAL CYCLONE...THIS IS THE GENERIC TERM FOR A SYSTEM
THAT WAS ONCE A HURRICANE OR TROPICAL STORM...BUT IS NO LONGER
CONSIDERED TO BE PURELY TROPICAL IN NATURE.  WHILE THESE SYSTEMS
TEND TO BE WEAKER THAN THEIR TROPICAL COUNTERPARTS...THEY MAY
STILL CONTAIN HIGH WINDS...HEAVY RAINFALL AND BE ACCOMPANIED BY A
STORM SURGE.

HURRICANE EYE...A RELATIVELY CALM AREA IN THE CENTER OF THE
TROPICAL CYCLONE.  IN THIS AREA...WINDS ARE LIGHT AND THE SKY IS
OFTEN ONLY PARTLY COVERED BY CLOUDS.  NEVER GO OUTSIDE IN THE EYE
OF A TROPICAL CYCLONE.  THIS PERIOD OF CALM WILL ONLY LAST FOR A
BRIEF PERIOD OF TIME BEFORE THE STRONG WINDS AND TORRENTIAL RAINS
RETURN.

STORM SURGE...AN ABNORMAL RISE IN SEA LEVEL ACCOMPANYING AN
INTENSE STORM.  THE HEIGHT OF THE STORM SURGE IS THE DIFFERENCE
BETWEEN THE OBSERVED LEVEL OF THE SEA SURFACE AND THE
ASTRONOMICAL TIDE THAT WOULD HAVE OCCURRED IN THE ABSENCE OF THE
STORM.  STORM SURGES OF 10 TO 20 FEET HAVE OCCURRED IN SOUTHERN
NEW ENGLAND...TOTALLY DEVASTATING THE COASTLINE.

TROPICAL STORM WATCH...THIS IS AN ANNOUNCEMENT THAT A TROPICAL
STORM...OR TROPICAL STORM CONDITIONS...POSE A THREAT TO THE
SPECIFIED AREA WITHIN THE NEXT 48 HOURS.  AN INLAND TROPICAL
STORM WATCH MEANS THE SAME THING...EXCEPT THERE IS NO NEED TO BE
CONCERNED WITH STORM SURGE.

TROPICAL STORM WARNING...THIS WARNING INDICATES A TROPICAL
STORM...OR TROPICAL STORM CONDITIONS...WILL AFFECT THE SPECIFIED
AREA WITHIN THE NEXT 36 HOURS.  AN INLAND TROPICAL STORM WARNING
MEANS THE SAME THING...EXCEPT THERE IS NO NEED TO BE CONCERNED
WITH STORM SURGE.

SAFFIR/SIMPSON HURRICANE WIND SCALE...THIS IS A SCALE RANGING
FROM 1 TO 5 BASED ON THE INTENSITY OF THE SURFACE WINDS.  THIS
CAN BE USED TO GIVE AN ESTIMATE OF THE POTENTIAL PROPERTY DAMAGE
FROM THE WINDS OF A HURRICANE.

HURRICANE WATCH...THIS IS AN ANNOUNCEMENT THAT A HURRICANE...OR
HURRICANE CONDITIONS...POSE A THREAT TO THE SPECIFIED AREA WITHIN
THE NEXT 48 HOURS.  AN INLAND HURRICANE WATCH MEANS THE SAME
THING...EXCEPT THERE IS NO NEED TO BE CONCERNED WITH STORM SURGE.

HURRICANE WARNING...THIS WARNING INDICATES A HURRICANE...OR
HURRICANE CONDITIONS...WILL AFFECT THE SPECIFIED AREA WITHIN
THE NEXT 36 HOURS.  AN INLAND HURRICANE WARNING MEANS THE SAME
THING...EXCEPT THERE IS NO NEED TO BE CONCERNED WITH STORM SURGE.

HURRICANE LOCAL STATEMENT...A PUBLIC RELEASE PREPARED BY YOUR
LOCAL NATIONAL WEATHER SERVICE OFFICE IN OR NEAR THE THREATENED
AREA.  THIS STATEMENT WILL CONTAIN SPECIFIC DETAILS ON WEATHER
CONDITIONS AND IMPACTS.  THIS STATEMENT MAY ALSO CONTAIN
INFORMATION ABOUT EVACUATION DECISIONS MADE BY LOCAL OFFICIALS
AND OTHER PRECAUTIONS NECESSARY TO PROTECT LIFE AND PROPERTY.

Do not say "Ground Zero Mosque" in front of these guys

This is beginning to sound like the Monty Python Mattress Skit.Each time someone asks a politician about the Ground Zero Mosque, said politician dons the Paper Bag of Stupidity.
This time, according this morning's Telegram article, GOP hopefuls oppose mosque, four of the five Republican candidates for the 3rd congressional district seat added the following to the public discourse about which we need not have an opinion:

  • Candidate Michael P. Stopa of Holliston said he wouldn’t oppose construction if he knew the mosque would be under FBI surveillance once it opened.
  • Brian J. Herr of Hopkinton magnanimously declared there is no need to spy on a house of worship. But he opposes the plan to build the Islamic center, saying it is insensitive to 9-11 families and to people who live and work near ground zero. 
  • Robert A. Delle of Paxton, formerly of Westboro, said he was concerned that the growth of Islam is the greater threat. “We’re just passively watching as Islam is expanding,” he said.
  • Robert J. Chipman of Plainville and Martin A. Lamb of Holliston were offered surprisingly temperate remarks, saying that  two blocks from ground zero is the wrong location for an Islamic center.
I've not been able to locate any public comment by the current office-holden, Rep. Jim McGovern, regarding this or any other mosque. Congressman, your silence is appreciated.

More on food

Yesterday's Telegram editorial, Peeling the egg (paywall content), about the recent crop of salmonella and legislation that would strengthen federal food inspection includes a couple of interesting points.
Consumer choice and free markets do far more daily for food safety than government. Americans reject foods that are out-of-date, spoiled, or fail to meet their standards. Stores and producers who wish to remain in business have no choice but to respond — witness the voluntary food safety programs of many major corporations.  
That's true. I'm probably not going to buy contaminated eggs, Cadmium Happy Meals, or more than my minimum daily requirement of E. coli  a second time, if there is a second time.
Also, the editorialist and commenters note that consumers should buy locally-produced products. Good option, but not a guarantee, either. Witness the listeriosis outbreak a few yeas back, when three people died and one woman miscarried as the result of the infected milk. Whitter Farms closed its Shrewsbury operation and now sells milk that is produced at its Connecticut plant.
It's a reminder that growing, processing, and distributing food is a complex process. There are many intersections at the international, national,  local, and household level where trouble can occur, often serious, sometimes deadly.
The gold standard for process quality, Six Sigma, sets a goal of establishing processes that can produce 99.9997% defect-free products. Or, 3.4 defects per million. That's a pretty good standard, unless it's your breakfast.
It should be noted that the companies under investigation for the latest large shipments of salmonella, Wright County Egg or its Maine affiliate, Quality Egg, make no claim for six sigma quality.
The bill in question, S. 510: FDA Food Safety Modernization Act (GovTrack.us), appears to have the support of big food businesses and associations with opposition from organizations that represent small farms. However we decide the issue, let's get our thinking in order. We can only vote with our feet on the issue of food safety if we're still on our feet.

Obligatory weather grumble

As if things weren't vexing enough, the weather does a double back-flip. At the end of last week, we needed a small fire in the stove in the morning. Now, it's gonna be hot enough to grow sun-dried tomatoes on the vine. Then, we might or might not get a visit from Earl. Then, cool again.
Sandra prefers the color of the trees in May and June, when the green is fresh. Me? I like late summer. The sun is lower in the sky, so the shadows of the leaves on their neighbors sharpens the color.
That's what you get with New England weather - something for everyone. Or, more precisely, there will always be plenty of people who don't like the weather that we're having.

Tropical Storm Earl Coordination Message #1

---------- Forwarded message ----------
From: SkyWarn Announcement List <SkyWarn-list@oak.powersrvcs.net>
Date: Sun, Aug 29, 2010 at 7:19 AM
Subject: Tropical Storm Earl Coordination Message #1
To: Skywarn-list@oak.powersrvcs.net


Hello to all..

..Tropical Storm Earl is expected to intensify into a hurricane later today with impacts to the Northern Leeward Islands and then intensify into a major hurricane over the next 3 days as it gradually turns west-northwest to northwest in the Western Atlantic Ocean..
..Latest computer models suggest a 'glancing blow' of minimal tropical storm force conditions to Cape Cod and the Islands in the late Thursday Night to Friday Night timeframe with the potential of a more western track towards the coast based on other reliable computer models. Track guidance can change considerably over the next several days to be either closer or further away from the coast..
..Interests in Southern New England should begin monitoring the progress of Tropical Storm Earl. This message's intent, at this very early stage, is to have folks begin that monitoring process..

Tropical Storm Earl is expected to strengthen into a hurricane today and pass near or just north of the Northern Leeward Islands late tonight and Monday. This may prompt the activation of the National Hurricane Center Amateur Radio Station, WX4NHC, and the HF Hurricane Watch Net and VoIP Hurricane Net late tonight or Monday depending on Earl's anticipated intensification and how close it approaches the islands. Earl will affect portion of the Northern Leeward Islands with tropical storm force conditions but its hurricane force conditions may stay just offshore though any slight deviation to the south may result in hurricane force conditions over parts of the Northern Leeward Islands.

After Earl's passage near the Northern Leeward Islands, Earl is expected to continue west-northwestward and then eventually northwestward and northward over the next several days intensifying into a major hurricane. Some of the latest computer models indicate a track far enough way from Southern New England to spare a direct hit but close enough to provide a glancing blow of minimal tropical storm force conditions to Cape Cod and the Islands in the late Thursday Night to Friday Night timeframe. Other reliable computer models bring Earl much closer to Southern New England in that timeframe and if that were to verify, more significant conditions would affect a larger portion of the region.

It is too early to say what the eventual track from Earl will be. Right now, tracks on Earl range from a 'glancing blow' to a possible direct impact. Later today or as we go through the week, one of those solutions could verify or Earl could be further out to sea. The purpose of this coordination message is to create situational awareness for SKYWARN Spotters, Amateur Radio Operators and Emergency Management to prepare to monitor this system. This is based on Earl's mention in the NWS Taunton Hazardous Weather Outlook and Area Forecast Discussion.

Regardless of the track, swells and rip currents that have started from Hurricane Danielle and resulting in a High Surf Advisory for much of today over Cape Cod and the Islands may wane as Danielle departs further out to sea only to increase and become more significant than today as Earl tracks closer to the region later this week. There have been many times where offshore tropical systems have caused injuries or fatalities on the water from the surf and rip currents so folks swimming at area beaches over the next several days with the hot weather expected are advise to heed the advice of lifeguards and monitor NWS Taunton products for high surf advisory information. See link below for the NWS Taunton High Surf Advisory statement for today and for future statements and also the surf zone forecasts for more information:
