Today TRMM satellite also flew above tropical storm Leepi just to the east of the Philippines at 0947 UTC. Data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments found the most intense rainfall in powerful storms near Leepi's center and in rain bands spiraling into Leepi from the south. TRMM PR data were used to make this 3-D view of tropical storm Leepi's vertical structure. Some of the powerful storms near Leepi's center reached heights above 16.5km (~10.25 miles). Tropical storm Leepi is predicted by the Joint Typhoon Warning Center (JTWC) to increase slightly in

The Observatory is now going through pre-vibration activities, including solar array deployments.

Tropical Storm Andrea formed on the late afternoon of June 5th, 2013 from a trough of low pressure that had persisted for several days over the southeast Gulf of Mexico. This trough extended out over the Gulf from the Yucatan Peninsula and provided the focus for the development of showers and thunderstorms in the region, eventually leading to the formation of Tropical Storm Andrea. With its suite of passive microwave and active radar sensors, TRMM is ideally suited to measure rainfall from space. For increased coverage, TRMM is used to calibrate rainfall estimates from other additional
