ATL : EX TOMAS - Discussion

[plasticup]

The eye is really firming up now

[jinftl]

has a storm had this impact on these same islands since ivan??? i am stating that without doing the research to back the claim up....welcome being corrected!!!

Reports of lots of trees down, roads blocked, hospital roof off and Hewanorra International Airport flooded - sea surge not rain. And Tomas is still only on his way. St Vincent must be getting hammered. Caribbean sea looks wild - expat2 how are you getting on in your boat?

The John Hope rule of the Eastern Caribbean graveyard doesn't apply in this case as Tomas formed east of the islands.

Rough day down there.. St. Lucia looks like some extended eyewall time.. Martinique not much better..

Hi Chris,

All fine here. We are rolling a little. Heavy wind gusts. I'm surprised but happy that the rain is so moderate. The palm trees look frightening though. Not looking forward to the next few hours.

Dark clouds and some gusty wind here in Antigua. Some rain has just started.

Martinique wind, local time, in KT

Even though ST Maarten is way north of the main action of Tomas,they are getting scattered showers with some gusty winds as the web cam shows.This indicates that where I am in Puerto Rico,will get plenty of rain that will be enhanced by the orografic effects of the mountains in the central part of the island.

When was the last time there were two simultaneous hurricanes in October?

[Squarethecircle]

When was the last time there were two simultaneous hurricanes in October?

Furthermore, what was the latest point in a season at which there were simultaneous hurricanes?

[Ad Novoxium]

I'm not sure about October, but I think the record latest was 2001 with Michelle and Noel.

Excerpt from discussion by Dr. Jeff Masters this morning:

Tomas' formation ties 2010 with 1995 and 1887 for 3rd place for most number of named storms in an Atlantic hurricane season. Only 2005 (28 named storms) and 1933 (21 named storms) were busier. Atlantic hurricane records go back to 1851, though there were likely many missed named storms prior to the beginning of satellite coverage in the mid-1960s. The intensification of Shary and Tomas into hurricanes today brings the total number of hurricanes this season to twelve, tying 2010 with 1969 and 1887 for second place for most hurricanes in a season. The record is held by 2005 with fifteen hurricanes, and I don't think we'll beat that record this year!

The formation of Tomas so far south and east this late in the season is unprecedented in the historical record; no named storm has ever been present east of the Lesser Antilles (61.5°W) and south of 12°N latitude so late in the year. Hurricane Six of 1896 came close--it was also a tropical storm south of 12°N and east of 61.5°W on October 29, but nine hours earlier in the day. That storm recurved to the north and missed the Lesser Antilles.

Tomas' track through the southern Lesser Antilles so late in the year is unprecedented. There have been only two other tropical storms that formed after October 15 south of 12°N and east of 61.5°W: Hurricane Jose, which was a tropical storm in that region on October 18, 1999, and Tropical Storm Nicolas, on October 16, 2003. Tomas most reminds me of a storm I flew into with the Hurricane Hunters--Hurricane Joan of 1988, which was a tropical storm on October 14 near Tomas' current location, and later strengthened into a Category 4 hurricane that hit Nicaragua. According to Chenoweth (2008), Tomas is the first tropical storm to cross through the Lesser Antilles Islands south of 16°N this late in the year since 1724. In that year, a tropical storm on 12 November crossed the islands at 13.7°N 61.5°W, and later became a hurricane that affected Jamaica. There was also a hurricane on 30 October 1671 that crossed 61.5°W at 13.3°N, and did damage on Barbados.

Another unusual aspect of Tomas' formation is that we now have two simultaneous hurricanes in the Atlantic Ocean on October 30. There has been only one hurricane season since 1851 that had had two simultaneous hurricanes later in the year--1932, when Hurricane Ten and Hurricane Eleven both existed November 7 - 10.

Today is also the 5th latest date in the season that there have been two simultaneous named storms in the Atlantic. The record was set way back in 1887, when Hurricane Eighteen and Tropical Storm Nineteen were both active on December 8. There were three years that had simultaneous November named storms: 1932, 1961, and 2001.

I can't really get a good fix on this system, thanks to the unusual infrared display. It looks like it is getting ready to go through a case of rapid intensification in about 6 to 12 hours, but I cannot be sure.

Notice the pressure rise and windspeed drop in Hewanorra..between bands I would guess..

At the 5pm update today, between Tomas and Shary... we will pass 150 in ACE, making 2010 a hyperactive season by that definition (I'd say it already is, though!).

No question about that. 2010 has simply been an amazing season for tropical cyclone formation, and it still isn't over yet! Still 30 days to go til the offical end of the season.

The pressure didn't rise at Hewannora. They messed up the METAR code and erroneously reported 1017 mb at 15z, when it should have been 1007 mb.
