TRMM Satellite Sees Tomas’ Power Fluctuate
The Tropical Rainfall Measuring Mission (TRMM) satellite traveled over Tomas twice on Tuesday, Nov. 2. The second time was at 2005 UTC (4:05 p.m. EDT) when it was still classified as a tropical storm. During TRMM's second overpass, Tomas' center of circulation wasn't evident. Today, Nov. 3 that center is reforming.
During the morning hours on Nov. 3, an Air Force hurricane hunter aircraft found no tropical storm force winds so Tomas was downgraded by the National Hurricane Center to a tropical depression.
A Tropical Storm Watch has now been posted for Jamaica, and Haiti, the Dominican Republic, southeastern Cuba, the southeastern Bahamas and Turks and Caicos Islands should watch Tomas' track.
Tomas is expected to produce total rain accumulations of 5 to 10 inches over much of Haiti with possible isolated maximum amounts of 15 inches.
Tomas is now predicted to strengthen into a tropical storm and not reach hurricane strength. An upper level trough is predicted to steer a stronger Tomas through the Windward Passage between Cuba and Haiti by Friday.

The yellow and green areas indicate moderate rainfall between .78 to 1.57 inches per hour. Credit: NASA/SSAI, Hal Pierce
