During the past week many areas of the United States from Kansas to the Atlantic seaboard have been hit by heavy rainfall. Flash floods have created hazards in several areas from Texas to Washington, DC. Some parts of Texas got more rain in two days than received in the past year. Tornadoes were reported in some part of the United States every day of the past week except Tuesday from May 9-16, 2014. The TRMM Multi-Satellite Precipitation Analysis (TMPA), produced at Goddard Space Flight Center, combines the rainfall estimates generated by TRMM and other satellites (3B42). The analysis above

Severe weather was extending from Minnesota to southern Texas on Thursday afternoon and Friday morning. During that time there were three tornadoes reported in Minnesota, two in Colorado and two in Missouri. The TRMM satellite flew above tornado spawning thunderstorms in the southern United States on May 9, 2014 at 0115 UTC (May 8, 2014 at 8:15 PM CTD). A rainfall analysis from TRMM's Precipitation Radar (PR) and Microwave Imager (TMI) is shown overlaid on a GOES-EAST infrared image received at the same time. TRMM's PR instrument found rain falling at a rate of over almost 163 mm/hr (about 6.4

A tropical low was affecting southern India and Sri Lanka on May 6, 2014 at 0809 UTC when the TRMM satellite flew above. The TRMM satellite was launched by NASA and JAXA in 1997 with the first earth orbiting active/passive instrument package to study the intensity and structure of tropical rainfall. The GPM satellite that was launched on February 27, 2014 will continue TRMM's highly successful mission of monitoring precipitation from space. TRMM' Precipitation Radar (PR) data were used in this 3-D view (from the west) of rainfall structure within this area of disturbed tropical weather. TRMM

The TRMM satellite had a good view of recent extreme rainfall over the Florida panhandle that caused extensive flooding. TRMM Multi-satellite Precipitation Analysis (TMPA) data were used at NASA Goddard Space Flight Center to estimate total precipitation (mm) for the week from April 24 to May 1,2014. Rainfall totals of up to 620 mm (about 25 inches) were analyzed in the Pensacola, Florida area. The continuous "training" of heavy rainfall into the area was viewed several times by the TRMM satellite. The TRMM satellite flew above the area on April 30, 2014 at 0128 UTC (9:28 PM EDT April 29, 2014

The GPM spacecraft continues to perform normally. The GPM Microwave Imager and Dual-frequency Precipitation radar continue operations and calibration. The spacecraft performed two routine maneuvers. The first was a 180-degree yaw (left/right in the horizontal plane) turn. This is the second yaw turn that changes the orientation of the spacecraft; it is now flying forwards again. Yaw turns are performed approximately every 40 days for thermal control, as the angle between the spacecraft's orbit and the sun changes. This keeps the side of the spacecraft designed to remain cold from overheating
