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.

Looks like the loop current is about to pop off an eddy.
It bodes well for the early part of the season in the GOM, since it won't be a really warm eddy. It bodes badly for the peak of the season, since the loop current may be able to reform a full loop by then.
Her is the 30 day forecast for the loop. It does pinch off, but does not move much...(it stops for a sec amid the run, sry)

Ohhh ok, the makes sense, sorry to hear about the cancer...

Interesting though about the weather there, because we have had relatively lame weather since 07, the last few years overall haven't been as active overall as most of the previous 16 years living here. Hopefully this year that will change. Not say we haven't periods of wild weather, but usually you expect s solid 4 to 5 months straight of crazy thunderstorms and heavy rain here, we had some still of course, but not as frequent or s reliable as I grew up with.
When I was living in S.W Florida in the 70,s and 80,s, there were numerous bad storms that we had gone through. Some of them were very intense. Most where violent summertime thunderstorms that were over 60,000 thousand feet high, conditions for this kind of extreme event seemed to happen more often back then. I dont know why. The other bad ones were associated with cold fronts and rapidly developing squall lines that were exceptionally brutal, and did tremendous damage to the marinas in our area.

The WRF run there doesn't seem right, there will be plenty of dynamics to not only keep that line strong and solid into Florida, but if anything intensify and also support a few severe storms.

LOOP CURRENT VERY PROMINENT THIS YEAR by Mark Sudduth from hurricanetrack.com

The much talked about Loop Current, which was mostly non-existent in 2010, has made quite a comeback so far this year. What is the Loop Current? It is overall part of the Gulf Loop Current/Florida Current system. Warm water is almost literally injected from the warm Caribbean Sea, northward through the Yucatan Channel, and in to the Gulf of Mexico. The current flows clock-wise and then itself passes through the Florida Straits and in to the western Atlantic Ocean- becoming the Gulf Stream. This is why, during the BP Oil Spill Crisis last year, the Loop Current received so much attention in a non-hurricane fashion. Of course, in 2005, the Current was much maligned for its role in strengthening hurricanes such as Katrina, Rita and Wilma. Last hurricane season, the Loop Current was mostly subdued and did not penetrate very far to the north in to the Gulf of Mexico, not that it mattered much since hurricane activity in the Gulf was virtually nil. However, when the Loop Current is prominent, as we saw in 2005 (and 2004 to some extent), it can become a significant source of energy for tropical cyclones. The reason is fairly simple: the Loop Current is constantly moving, providing vast amounts of warm water that itself contains a tremendous amount of energy. When a hurricane passes over the Loop Current, the constant re-supply of warm water, often several degrees warmer than the surrounding Gulf waters, provides a booster shot of heat for the hurricane to tap in to. If upper level conditions are favorable, explosive development is often the rule and leads to powerful hurricanes as we saw time and again in 2005. And it goes without saying, the farther north in to the Gulf the Loop Current penetrates, the closer to land a hurricane can take advantage of extra warm water.

If you take a look at the image (click on it to enlarge), you can clearly make out the shape of the Loop Current in the Gulf. Not only is it very prominent this year, it is also providing warmer than normal sea surface temperatures to the region- in some cases, several degrees above normal. The once cold Gulf of Mexico, chilled by the relentless winter we just endured, is now running above normal in most of the region. Whether or not the current state of the Loop Current will remain in place until the hurricane season begins is tough to say. I could not find any solid reasoning as to why some years the current is more robust than in others. Often times, a warm eddy will break off the main current and drift WSW towards Texas- thus pinching off a piece of the Loop Current and reducing its overall impact on the Gulf. However, these warm eddys themselves provide ample warm water for tropical cyclones to tap. It's nothing to be alarmed about as it stands right now, but rather something to keep an eye on if and when a tropical storm or hurricane ventures in to the area.

Yesterday the number of missing rose by more than 1,400 and today fell by more than 1,200. I don't know why.

That's pretty impressive has the Ruskin office seems to be behind the 8 Ball all the time. Nice to see they are on the same page as everyone else. Remember i told you last week that we were in for some serious rain this week and it is verifying. Myself and Hydrus were trying to say last week that we are in for one big pattern change and the rain this week is the start of an active pattern for FL that could last the whole month of April. I wonder if this is a refecting of the rapidly weaking La-Nina that we've had over the last several weeks. This could be the reason for such a switch in the pattern that has been over FL. If you notice the thing that was lacking lately has been the none existance of the Southern Jet now that we have the Southern Jet activated again now we are getting very stormy wx over the SE US. This WX pattern is bad news for tornado chasers out in the Midwest because it looks very quiet for them for atleast until Mid April.



Yeah I agree, this could quite possibly be the sign of a very wet period for Florida in the heart of the dry season, this may be a sign of how this year will be considering this isn't El Nino. It may also be a sign of La Nina losing its power because heavy rain in late March and April in Florida is a complete counteract to La Nina no doubt.

I had a hard time believing 4 to 8 inches of rain could fall this week in some places but you were right. You have to understand as a student training to become an actual meteorologist I gotta be cautious anytime computer models paint big bulls-eyes over Central Florida in the dry season when there isn't a El Nino present. I have seen so many times the models paint big swaths of rain here during a dry period and the models back away in the last day before it happens and it turns out we get nothing.

However, considering what we just had yesterday, I have more confidence that we are gonna get another wild round of heavy rain, and possibly severe weather this Thursday.

We should definitely keep a close eye on the models for next week to see if they keep bring another big system into play.

653 NRAamy " TROLL ALERT!!!! "

"...It gets better..."

- - - - - - - - - - - - - - - - - - - - - - - - - - -

"...average...naturally occurring background radiation [is] 0.17-0.39 microsieverts per hour."
Times 8766hours per year equals ~1490to3420microsieverts or 1.49to3.42millisieverts per year.

The typical worker at a nuclear plant is exposed to 2to3 millisieverts of excess*radiation per year. Plant operators really really like to keep it as low as reasonably achievable under 3millisieverts. More means they hafta start thinking about radiation leaks... and initiate searches for them.
Assuming a work-year of 2000hours (fifty 40hour workweeks & a 2week vacation), workers receive an excess of ~1to1.5microsieverts per hour on the job.

"Officials acknowledged there was radioactive water in all four of the Fukushima Dai-ichi complex's most troubled reactors, and that airborne radiation in Unit 2 measured 1,000 millisieverts per hour ..."
Divided by ~1to1.5microsieverts pet hour equals the radiation level is between ~1million and 666thousand times the level typically encountered at a nuclear plant.
Outside of nuclear powerplants, Japan's natural background radiation is toward the lower end of the world average. ie The radiation leaking at the power plant is between 5.9million and 2.6million times Japan's normal background level.

So what kind of idjit headlines news stories with "Radiation Leak Is only 100 Thousand Times above Normal" or "Radiation Leak is only 100 Thousand Times above Normal in Japan?
Yeah, some of the articles go on to correct that to be "...100thousand times what is normally found in the reactor core coolant water...". But mentioning that caveat once, without any emphasis, somewhere within a lengthy article following a HUGE headline, is nearly as deceptive to the average reader as expecting a client to read&understand a fine print addendum to a legal contract.

* Excluding natural background radiation and radiation received from medical procedures.

POSSIBLE IN AREAS THAT SEE REPEAT THUNDERSTORMS. GIVEN THE DRY
CONDITIONS OVER THE LAST TWO AND A HALF WEEKS...FLASH FLOODING IS
NOT EXPECTED TO BE A MAJOR CONCERN...HOWEVER...LOCALIZED FLOODING
IS POSSIBLE WHERE THE HEAVIEST RAINFALL AMOUNTS OCCUR.
