Tropical Storm Tomas Moving Away from Fiji Islands


The Tropical Rainfall Measuring Mission satellite, also known as "TRMM" passed over powerful tropical cyclone Tomas near the International Dateline in the South Pacific on March 15 at 2123 UTC (5:23 p.m. EDT). TRMM detected very heavy rainfall of over 50 mm/hr (~2 inches) mainly in Tomas' southeastern quadrant.

Cyclone Tomas hit the north and east areas of Fiji as a Category 4 Cyclone on the Saffir-Simpson Scale, and has now moved south of them. NASA's Tropical Rainfall Measuring Mission satellite captured an image of the heavy rains that were falling in Tomas during his swath of destruction in the Fiji Islands.

Tropical Storm Tomas (Southern Pacific)

Tropical Storm Tomas Approaching Nadi This Weekend


Tropical Storm Tomas is on a southern track in the South Pacific Ocean, and residents of Nadi, Fiji will be watching it as it approaches the eastern side of the island late this weekend. A tropical cyclone alert is in effect for all of Fiji this weekend.

Nadi is located on the western side of the main island of Viti Levu, Fiji. Fiji Standard Time is 17 hours later than Eastern Standard Time.

NASA's Aqua satellite flew over Tomas from space and captured in infrared image from the Atmospheric Infrared Sounder (AIRS) instrument. The AIRS image on March 11 at 20:10 UTC (3:10 p.m. ET) showed a developing storm with a large cluster of high, cold (purple), strong thunderstorms around Tomas' center.

Tropical Storm Tomas had maximum sustained winds near 57 mph (50 knots) and it was located near 11.6 degrees South and 177.6 degrees West. Tropical storm force winds extend about 150 nautical miles from the center of the storm, making Tomas about 300 miles wide in diameter.

Tropical Storm Hubert (Southern Indian Ocean)

Hubert has maximum sustained winds near 39 mph (35 knots) and is moving west-southwest near 6 mph (5 knots). At 10 a.m. ET (1500 UTC) on March 10, Hubert was located about 160 nautical miles southeast of the capital city of Antananarivo, Madagascar near 20.9 South and 48.8 East.

As Hubert continues moving inland over the next two days, forecasts for the capital city and other areas in south central Madagascar will continue to experience periods of moderate to heavy rainfall, and gusty winds.
