Hurricane Season 2007: Humba (Western Pacific)
Tropical Cyclone Humba Fading Away in the Indian Ocean

After forming on Thurs., Feb. 22, and quickly gaining intensity, tropical cyclone Humba is now dissipating as it continues to travel over the open waters of the Indian Ocean.

At 10:00 a.m. EST (1500 UTC) on Mon., Feb. 26, tropical cyclone Humba was located near 24.4 degrees south latitude and 78.3 degrees east longitude, or about 1050 miles south-southeast of Diego Garcia and was moving toward the south at 12 knots (14 mph). Maximum sustained winds were near 50 knots (58 mph), with gusts to 65 knots (75 mph).

A ridge (elongated area of high pressure) near Australia continues to track Humba on a southerly path. The cyclone is transitioning into an extratropical system, with a warm front developing just to the east of its center. Forecasters expect Humba to becoming fully extratropical by early Tues., Feb. 27. Wind shear (changing wind speed and direction with height) combined with cooler sea surface temperatures along its path will contribute to its demise.

This image of Tropical Cyclone Humba was taken by the Tropical Rainfall Measuring Mission (TRMM) satellite at 4:01 a.m. EST (901 UTC) on Mon., Feb. 26. It shows a top-down-view of rain intensity. Estimated rain rates of 25 to 40 millimeters (0.98 inches to 1.57 inches) per hour were common close to the storm center. TRMM is a joint mission between NASA and the Japanese space agency JAXA.
