Not much convection only low to mid-level clouds with it although for those who like to see naked swirls this one looks pretty good. By the way the Floater has not been set for the low but it has been in that position for many weeks and the low is getting away from view at floater as it moves out to sea.

Window of oppertunity is starting to close. Looks like the low is starting to get picked up by the trough and making its move to the NE. It will be long gone in a day or two......MGC

It's just too early. If sst's were warmer than the storm would have a much better chance of developing.

Just curious, what storm was the Floater on so we can see what we see right now? Was it Jeanne or Matthew, another one?

If I recall I haved seen the floater in that area since January maybe they focused on a strong low that later moved NE parralell to the EC was one of the winter storms in that month.

Thursday, April 20th at 11:00 PM EDT will be the two year anniversary of the first advisory issued for Subtropical
Storm Ana that subsequently became Tropical Storm Ana a day and a half later, at 11:00 AM on the 22nd.

Edit to correct typo... 21st to 20th in first line.

Tropical Cyclone Report

Tropical Storm Ana
20 - 24 April 2003
Jack Beven
National Hurricane Center
19 December 2003
Ana was the first Atlantic tropical storm of record to form in April. It moved generally eastward across the central Atlantic.
a. Synoptic History
A non-tropical low formed about 210 n mi south-southwest of Bermuda on 18 April when an upper-level trough interacted with a surface frontal system. Moving generally northward, the low produced sporadic bursts of central convection starting early on 19 April. After turning northwestward, the low looped back toward the southeast early on 20 April. The central convection became better organized and the low separated from the frontal system. It is estimated the low became a subtropical storm at 0600 UTC 20 April about 215 n mi west of Bermuda. The "best track" chart of Ana's path is given in Figure 1, with the wind and pressure histories shown in Figure 2 and Figure 3, respectively. The best track positions and intensities are listed in Table 1.

Additional development occurred during its first day, and based on satellite microwave data showing a warm core it is estimated that Ana became a tropical storm near 0000 UTC 21 April with winds of 50 kt. This would be the peak intensity of the system. Ana turned east-southeastward on 21 April and eastward the next day while maintaining 45-50 kt winds. The system turned east-northeastward on 23 April while gradually weakening, and it merged with a cold front the next day about 810 n mi east of Bermuda.

Ana continued eastward as a 30-35 kt extratropical low through 25 April. It turned east-northeastward with some intensification on 26 April, then it was absorbed by a frontal system between the Azores and Portugal the next day.

Ana is the first tropical storm of record in April in the north Atlantic basin. The only other tropical or subtropical cyclone known in April is a subtropical storm between Puerto Rico and Bermuda from 21-24 April 1992.






Tom as you can see from the NHC report of Ana she was named on the 20th Sub-Tropical Storm Ana and on the 21rst Tropical Storm Ana.

I looked up the information for the times. Strange that they would be different.

I wouldn't come up with information, that's inaccurate.
