Tropical Cyclone Uriah (13S) in the South Indian Ocean

On February 17 at 04:50 UTC (February 16 at 11:50 p.m. EST) the Moderate Resolution Imaging Spectroradiometer (MODIS) flying aboard NASA’s Terra satellite passed over Tropical Cyclone Uriah and captured a true-color image of the intensifying storm. At the time the image was captured, the storm sported a 19 nautical mile-wide eye and bands of thunderstorms wrapped into the low-level center from the eastern and southern quadrants.

Tropical Cyclone Uriah peaked at Category 4 strength on February 17 with maximum sustained winds at about 125 knots (143.8 mph/ 231.5 km/h). Fortunately it remained far out to sea and away from land. The Global Disaster Alert and Coordination System (GDACS) reported that, throughout the storm, 0 people were affected by Category 1 (120 km/h) wind speed.

By February 18 Uriah was fighting strong vertical wind shear, and the winds had dropped to 90 knots (103.6 mph/ 166.7 km/h) early in the day. It was spinning about 1,108 mi (1,783 km) south-southeast of Diego Garcia and moving to the south at 12.6 mph (20.3 km/h). By February 20 Uriah had become a post-tropical depression and the last warning was issued on the storm.
