Tropical Page
This page contains abbreviated tropical weather information for the Atlantic. This page is just meant as a quick "snapshot" for tropical weather information. Please read the disclaimer at the bottom of this page. Special thanks goes to NOAA and The Weather Underground for the graphics displayed on this page.

Current Tropical Activity from AllWeatherFriends
This image shows current tropical activity in the Atlantic and Pacific. Current storm strength, location, forecasted track, and forecasted strength are shown.
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.
Current unified surface analysis of the Tropical Atlantic and Pacific
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.
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.
6 Hour GFS Forecasted Sea Level Pressure, and 1000mb (surface) Winds
This is the forecasted (6 hour) sea level pressure, and surface wind direction for the tropical Atlantic. On this map, you can see low and high pressure areas, and the wind direction in a given location. Areas of high pressure such as the Bermuda High, as well as other features, help steer tropical weather systems.
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.
