Tropical Update

We are watching three areas in the Atlantic for potential tropical development…

A tropical wave located over the eastern Caribbean Sea is producing disorganized showers and thunderstorms, along with gusty winds. Significant development of this system is unlikely during the next day or so while it moves west at about 20 mph across the eastern and central Caribbean Sea. After that time, the wave is forecast to move more slowly WNW and a tropical depression is likely to form late this week or this weekend when the system reaches the northwestern Caribbean Sea.

* Formation chance through 48 hours: Medium (40%)

* Formation chance through 5 days: High (80%)

An elongated area of low pressure located a little over 1000 miles east of the Windward Islands continues to produce a concentrated area of showers and thunderstorms mainly on the west side of the disturbance. Environmental conditions are conducive for further development, and a tropical depression is expected to form during the next day or two while the system moves generally WNW at 15 to 20 mph across the central and western portions of the tropical Atlantic.

* Formation chance through 48 hours: High (90%)

* Formation chance through 5 days: High (90%)

A large area of showers and thunderstorms located over Guinea, Africa, is associated with a vigorous tropical wave. Environmental conditions are expected to be marginally conducive for some development of this system while the wave enters the extreme eastern Atlantic on Friday. By early next week, however, conditions are forecast to become less favorable for tropical cyclone formation while it moves WNW at 15 to 20 mph toward the central tropical Atlantic.

* Formation chance through 48 hours: Low (near 0%)

* Formation chance through 5 days: Low (20%)
