A Giovanni user image shows the rain rate from Hurricane Tomas in the early morning hours of November 5, using data from the Tropical Rainfall Measuring Mission (TRMM). The rain rate over the eastern coast of Jamaica and in a rain band over the northern coast of the Dominican Republic was 18-20 mm of rain per hour, as measured by the satellite's precipitation radar. (Note that instantaneous rain rates measured by rain gauges or surface weather radar can be significantly higher, as the satellite data is averaged over a 3-hour period and over an area on the Earth's surface.)
As of noon Eastern Daylight Time on November 5, the center of Tomas was located near the Windward Passage between Cuba and Haiti. There are significant concerns about flooding, landslides, and disease in the disaster-stricken country of Haiti, as well as for the other affected Caribbean islands in the path of Tomas.
