SPECIAL TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
1205 PM EDT SAT APR 23 2011

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

SHOWER ACTIVITY ASSOCIATED WITH A NON-TROPICAL LOW CENTERED ABOUT
360 MILES NORTH OF SAN JUAN PUERTO RICO HAS DIMINISHED...AND
UPPER-LEVEL WINDS HAVE BECOME HIGHLY UNFAVORABLE FOR DEVELOPMENT.
THE LOW IS EXPECTED TO WEAKEN AND MOVE GENERALLY WESTWARD DURING THE
NEXT COUPLE OF DAYS. THERE IS A LOW CHANCE...NEAR 0 PERCENT...OF
THIS SYSTEM DEVELOPING INTO A SUBTROPICAL OR TROPICAL CYCLONE
DURING THAT TIME. ADDITIONAL INFORMATION ON THIS LOW CAN BE FOUND
IN HIGH SEAS FORECASTS ISSUED BY THE NHC/TROPICAL ANALYSIS AND
FORECAST BRANCH...UNDER AWIPS HEADER NFDHSFAT2 AND WMO HEADER
FZNT02 KNHC. THIS WILL BE THE LAST SPECIAL TROPICAL WEATHER
OUTLOOK ISSUED FOR THIS SYSTEM UNLESS RE-DEVELOPMENT OCCURS.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.

Current Tropical Activity from wunderground.com

This image shows current sea temperatures, with an overlay of current tropical weather. It is generally accepted that sea temperatures at or above 26.5C or 80F are needed for tropical system development.

 

Tropical Cyclone Danger Areas (Atlantic)

Current forecast track and areas at risk from active tropical systems.

 

 

 

Tropical Storm Formation Probability within 24 hrs

This image shows the current genesis probability of tropical weather. It uses many factors to determine the probabilities, explained here.

 

24 Hr. Forecast for the Tropical Atlantic

This is a 24 hr. forecast for the tropical Atlantic, created by the NHC.

 

 

Current Shear in the Tropics

This is the current wind shear in the tropics. High wind shear is hostile to tropical development.

 

Current Water Vapor Image for the Tropical Atlantic

This is the current water vapor image of the tropical Atlantic. Water vapor images help point out important elements in the atmosphere, including dry air which can be hostile to tropical storm development.

 

 

 

100 Meter Potential Temperature

This map is very large in size, please click the link above to see it. This is the potential water temperature at a depth of 100 meters for the western Atlantic. Generally, most tropical systems need deep water (at least 50m) at a minimum temperature of 26.5C or 80F to sustain themselves. This graphic shows the potential water temperature at 100m.
