The Indian Ocean was alive with tropical activity on May 10, 2013, with a tropical storm in both the northern and southern oceans. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies aboard NASA’s Terra satellite captured this true-color image of compact Tropical Cyclone Jamala in the southern Indian Ocean and the much larger Tropical Cyclone One B (01B) in the Northern Indian Ocean on May 10 at 04:25 UTC (12:25 a.m. EDT).
On May 10 at 0900 UTC (5 a.m. EDT), Tropical Cyclone Jamala (formerly Cyclone 24S) had maximum sustained winds near 46 mph (74 km/h). It was centered about 926.4 miles (1,491 km) east of Diego Garcia. Jamala is crawling to the south-southeast at 3.4 mph (5.5 km/h). Forecasters at the Joint Typhoon Warning Center expect Jamala to shift westward in movement and intensify up to hurricane strength.
North of the equator in the Northern Indian Ocean, newborn Tropical Cyclone 01B developed from low pressure System 92B, and formed near the northern tip of Sumatra. On May 10 at 0900 UTC Tropical Cyclone 01B had maximum sustained winds near 40.2 mph (64.8 km/h). It was located 1,211 miles (1,948 km) south of Chittagong, India, was moving to the northeast at 4.6 mph (7.4 km/h) and was forecast to move northwest into the central Bay of Bengal.
Residents of northwestern Burma and eastern Bangladesh should keep a watch on Tropical Cyclone 01B. Forecasters at the Joint Typhoon Warning Center expect 01B to intensify into hurricane force and make landfall on May 14 or 15 in northwestern Burma and eastern Bangladesh.
