GPM

The GPM core observatory satellite twice flew almost directly above hurricane Celia in the eastern Pacific Ocean on July 12, 2016. The first time was on July 12, 2016 at 0011 UTC and the second view was on July 12, 2016 at 1326 UTC. With both passes GPM's Microwave Imager (GMI) clearly showed the location of rainfall around hurricane Celia's well defined eye. The hurricane had maintained intensity during this period with sustained maximum wind speeds estimated at 80 kts (92.8 mph). With the first pass GMI measured rain in the southwestern side of Celia's eye wall falling at a rate of close to

Nepartak was a powerful category four typhoon when it hit Taiwan last week but weakened to a tropical storm as it moved into the Taiwan Strait. Nepartak's winds and heavy rains caused severe problems when it moved ashore over southeastern China. Thousands of homes in China were destroyed by the storm. At least three deaths in Taiwan and six fatalities in China were attributed to Nepartak. Torrential rain caused flash flooding and mudslides in both Taiwan and China. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) were again used to estimate the total amount of rain that Nepartak

The first typhoon of 2016 called Nepartak developed in the western Pacific Ocean on July 3, 2016 south of Guam. Nepartak has moved to the west-northwest of Guam and has started to rapidly intensify. Warm water, low vertical wind shear and favorable outflow due an upper level trough are providing favorable environmental conditions for the typhoon. The GPM core observatory satellite flew above Nepartak on July 4, 2016 at 2151 UTC when the tropical cyclone was still classified as a tropical storm. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) data showed that Nepartak

Since last Thursday over two dozen people have been reported killed and hundreds of homes have been destroyed by flooding in West Virginia. The governor of the state declared a federal disaster after the worst flooding in a century. The prevalence of rough terrain in West Virginia has amplified the effects of flooding rainfall. The National Weather Service predicted that thunderstorms were going to fall in the area again today. More flash flooding with streams again coming out of their banks has been predicted. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) data were used in this

A slow-moving frontal boundary draped across the central US from the Central Plains across the Middle Mississippi and Ohio Valleys and into the Mid-Atlantic region has been providing the focus for numerous showers and thunderstorms the past few days while an associated East-West oriented, upper-level jet stream located near the front has helped to organize and strengthen the storms. This has lead to severe weather and flooding across the region. The latest episode began when thunderstorms formed and organized into a line across northern Illinois and southern Lake Michigan on the evening of

Tropical Storm Danielle started weakening after making landfall north of Tuxpan, Mexico on Monday evening just before June 21, 2016 at 0000 UTC (June 20, 2016 7:00 PM CDT). As Danielle weakened the low level circulation quickly became disorganized. The GPM core observatory satellite passed above rapidly weakening Danielle on June 21, 2016 at 0421Z (June 20, 2016 11:21 PM CDT). The approximate center of Danielle's circulation at the time of this GPM pass is shown with a red tropical storm symbol.

A tropical depression (TD4) in the southwestern Gulf of Mexico was designated tropical storm Danielle by the National Hurricane Center (NHC) this morning at 1500 UTC (1000 AM CDT). Danielle is the earliest fourth-named tropical storm to form in the Atlantic Basin. Danielle's life as a tropical storm is predicted to be short because it is moving almost due west and is predicted to move over the east coast of Mexico later today or tonight. Heavy rainfall is expected to cause flash floods and mudslides over eastern Mexico over the next few days. The GPM core observatory satellite flew above the

On June 8 the nodal weather agency of India (IMD) declared the arrival of the 2016 Southwest Monsoon over the Indian state of Kerala. This season is expected to be rainier than recent years. The El Nino conditions which have been blamed for recent disappointing monsoons has weakened to ENSO-neutral conditions. ENSO-neutral conditions are expected to transition to La Nina in the northern hemisphere by the fall and winter of 2016-17. La Nina conditions normally result in beneficial wetter and cooler monsoons in India. An animation of weekly rainfall totals was derived from NASA's Integrated
