Hurricanes Igor and Tomas get their names retired

The names Tomas and Igor will no longer be used to name hurricanes in the Atlantic, the World Meteorological Organization (WMO) announced this March. Hurricane Igor made landfall near Cape Race, Newfoundland on September 21, 2010, and was that island's most damaging hurricane in 75 years, with $200 million in damage. Hurricane Tomas smashed through the Lesser Antilles Islands on October 30 - 31, 2010, dealing a particularly harsh blow to St. Lucia, where eight died and damage was estimated at $500 million. Tomas also killed 35 people on Haiti, and contributed to a cholera epidemic that killed thousands.

The retirement of hurricane names
The WMO maintains a list of hurricane names for the Atlantic and Eastern Pacific that repeats itself every six years. The names Igor and Tomas in the Atlantic would have appeared again in 2016, but will be replaced by Ian and Tobias. Each spring, the WMO meets to decide if any names should be retired from the list, due to notable death or destruction caused by one of the past season's storms. Any country that is a member of the WMO can request that a name be retired. If a country seriously affected by a hurricane does not request retirement of the name, then the name will not be retired. In the recent past, Mexico, in particular, has been reluctant to request retirement significant storms that have affected them. In 2010, two significant hurricanes affected the country, but Mexico chose not to request retirement of either: Hurricane Alex, which killed twelve people and did $1.5 billion in damage, and Hurricane Karl, which killed 22 and did $206 million in damage. Back in 2005, Mexico also did not request retirement of Hurricane Emily, which made two landfalls in Mexico as a major hurricane, destroying thousands of buildings, but not claiming any lives. A new storm named Emily will appear this year, as we are recycling the names from 2005 that were not retired (2005 holds the record for most retired names, with five.) Probably the best example of a hurricane that did not get its name retired, but deserved to, was Hurricane Gordon of 1994, which killed 1145 people on Haiti. Haiti did not send a representative to the 1995 WMO meeting when retirements for 1994 were decided. Gordon did not affect any other countries strongly enough to motivate them to request retirement, and the name Gordon will be used again in 2012.

Since Atlantic hurricanes began getting women's names in 1953, 76 names have been retired, an average of 1.3 retired names per year. The list includes one tropical storm, Allison of 2001, that caused billions in damage from its heavy rains. The storm with the most appearances so far is Arlene, which has appeared nine times: 1959, 1963, 1967, 1971, 1981, 1987, 1993, 1999, 2005. Arlene will make its tenth appearance this year. One exception to the retirement rule: before 1979, some storm names were simply dropped. For example, in 1966, Fern was substituted for Frieda, and no reason was given. Only three Eastern Pacific hurricanes have had their names retired--Hurricane Ismael of 1995, Hurricane Pauline of 1997, and Hurricane Kenna of 2002. All of these storms hit Mexico.

Cool Katrina animation
A new visualization created by Advanced Visualization Laboratory at the National Center for Supercomputing Applications at the University of Illinois shows Hurricane Katrina spinning over the Gulf of Mexico during a 36-hour period in August, 2005. The animation is part of a full-length planetarium film called Dynamic Earth screened at the Fulldome UK festival on March 12 - 13. You can see the video at the newscientist.com or DynamicEarth web sites. The video description: Trajectories follow moist air rising into intense "hot tower" thunderstorms, and trace strong winds around the eye wall; rapidly rising air is yellow, sinking air blue. The sun, moon, and stars show the passing of time. The visualization highlights Katrina's awesome power and fierce beauty.

I'll be back with a new post Tuesday or Wednesday.

... Flood Watch remains in effect from Wednesday afternoon through
Friday afternoon...

The Flood Watch continues for

* portions of western Washington... including the following
counties... Clallam... Jefferson... Skagit... Whatcom... King...
Lewis... Mason... Pierce... Snohomish... Thurston... .

* from Wednesday afternoon through Friday afternoon

* a warm frontal system will spread rain into western Washington
later tonight and Wednesday. The frontal band is expected to
stall over the area for a 24 to 48 hour period producing heavy
precipitation along the coast and mountains. Freezing levels
will rise dramatically to 7000-9000 feet during the period
which raises the threat of flooding on some rivers.

* The Skokomish River in Mason County is the river most likely to
flood... possibly by late Wednesday. However... 48 hour rainfall
amounts of up to 5 inches in the Olympics and 4 to 7 inches in
the central Cascades will drive rivers such as Snoqualmie...
Snohomish... and stillaguamish to flood. There is a chance the
Snohomish river will reach major flood.

* Less amounts of rainfall are expected elsewhere but will cause
sharp rises on other Rives and may also cause some additional
rivers running off the Cascades and Olympics to flood. Grays
Harbor and Kitsap counties may also be impacted and could be
added to the Flood Watch later. Scattered landslides in areas
that receive heavy rain may also occur.

Precautionary/preparedness actions...

A Flood Watch means conditions are favorable for flooding but
flooding is not imminent or occurring. Monitor the latest
forecasts from the National Weather Service and be ready to act
quickly if flooding is observed or a warning is issued.

The Territory Controller advices communities under Watch that now is the time to put together your emergency kit, clear your yards and balconies and commence home shelter preparations.

Tropical Cyclone Watches/Warnings
====================================
A Cyclone WATCH has been declared for a developing tropical low for the Tiwi Islands.

AREAS AFFECTED...SERN LA/SRN MS/SWRN AL

CONCERNING...TORNADO WATCH 72...

VALID 300156Z - 300300Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 72 CONTINUES.

MOIST ISENTROPIC ASCENT...COMBINED WITH UPPER-LEVEL JET
SUPPORT...WILL CONTINUE TO ALLOW CONVECTION TO PERSIST/DEVELOP
ACROSS ERN PORTIONS OF TORNADO WATCH 72 DURING THE NEXT SEVERAL
HOURS...WITH SUPERCELLS POSSIBLE GIVEN EFFECTIVE BULK SHEAR
MAGNITUDES OF 40 TO 50 KT PER RUC ANALYSIS. SFC ANALYSIS REVEALS
MULTIPLE BOUNDARIES ACROSS THE AREA TO FOCUS CONVECTION THROUGH THE
REMAINDER OF THE EVENING HOURS:
1. A WARM FRONT EXTENDS FROM A SFC LOW OVER S-CNTRL LOUISIANA INTO
FAR SERN LA AND THE ADJACENT COASTAL WATERS...WITH DEWPOINTS IN THE
UPPER 60S AND LOWER 70S AND MLCAPE VALUES AOA 2000 J/KG SOUTH OF
THIS BOUNDARY. A CYCLIC SUPERCELL RIDING SEWD ALONG THIS BOUNDARY
THAT MOVED SOUTH OF YSCLOSKEY IS EMERGING INTO THE COASTAL
WATERS...WITH ADDITIONAL SUPERCELLS POTENTIALLY DEVELOPING UPSTREAM
ALONG THE WARM FRONT.
2. A SECONDARY WARM FRONT EXTENDS EAST OF THE LOW ACROSS SRN
MS...WHICH COULD ALSO ENHANCE CONVECTION THAT FORMS NORTH OF THE SRN
WARM FRONT.
3. NORTH OF THE SECONDARY WARM FRONT...SLIGHTLY ELEVATED INSTABILITY
EXTENDS TOWARD THE NRN PORTION OF THE TORNADO WATCH...WHICH COULD
SUPPORT A LARGE HAIL THREAT.

WITH 0-1-KM SRH VALUES OF 100 TO 200 M2 PER S2 ACROSS THE REGION
/105 M2 PER S2 BASED ON VWP AT LIX/...A MARGINAL TORNADO THREAT WILL
CONTINUE...WITH THE GREATEST THREAT NEAR EITHER OF THE WARM FRONTS.
THUS...ANOTHER TORNADO WATCH MAY BECOME NECESSARY PRIOR TO THE 03Z
EXPIRATION OF WW 72.
