The West Coast, which has been suffering from a strong drought, is finally seeing some much needed relief as a steady stream of storms and rain pour into the coast from the Pacific. The rains began in Washington and Oregon and have now worked their way down the coast to southern California. The weather pattern responsible for all of the rain is known as the "Pineapple Express." The Pineapple Express is known as an atmospheric river. A large, slow-moving low pressure center off of the West Coast taps into tropical moisture originating around the Hawaiian Islands, which is then channeled

As of Today, super typhoon Hagupit has been deadly with up to 27 deaths reported but the Philippines has been spared the widespread destruction caused by Super typhoon Haiyan in 2013. Hagupit's (called Ruby in the Philippines) forward motion slowed on December 4, 2014 before reaching the Philippines. After hitting Samar in the eastern Philippines Hagupit's continued slow movement resulted in high rainfall amounts along the typhoon's track. These high rainfall totals meant that flooding occurred frequently along the typhoon's track. When the TRMM satellite flew over on December 8, 2014 at 0132

Super Typhoon Hagupit is threatening the Philippines a little over a year after deadly Super Typhoon Haiyan devastated the island nation in November 2013. Hagupit was weakening slightly from peak wind speeds of 155 kts (178 mph) when the GPM core observatory satellite passed over on December 4, 2014 at 2304 UTC in the image shown above. Hagupit had winds of about 125 kts (144 mph) when viewed by the TRMM satellite on December 5, 2014 at 0308 UTC in the image shown below. Rainfall data from these satellites are shown overlaid on daylight views from the MTSAT-2 satellite captured at close to the

It has been very dry in the state of California for the past couple years. The lack of rain in 2013 and 2014 contributed to exceptional drought conditions in the state. Records were set over the past winter for the lowest winter snow packs recorded in a century. Rainfall produced by storms moving into California from the Pacific Ocean has recently brought some very temporary drought relief. Precipitation data (3B42) from various satellites such as TRMM and recently the GPM core observatory satellite have been collected, merged and archived at the Goddard Space Flight Center since 1998. The

Tropical storm Sinlaku formed on November 26, 2014 over the southeastern Philippines. As a tropical depression Sinlaku caused flooding in areas of the Visayas and Mindanao. The TRMM and the GPM core satellite viewed Sinlaku after it had strengthened into a tropical storm over the South China Sea. The first image shows rainfall derived from TRMM Microwave Imager (TMI) data collected when the satellite flew over on November 28, 2014 at 0716 UTC. The second view shows rainfall from GPM Microwave Imager (GMI) measurements received a little over six hours later at 1326 UTC. Rainfall was measured by

The NOAA network is gradually being restored. MHS data appears to have started flowing around 02:00 UTC on 23 October 2014, but as of 08:00 UTC on 23 October 2014 the Meteosat geo-IR data was still missing. As a result, users should see reduced areas of "missing" and higher-quality estimates in general starting with the 03:00 UTC 23 October 2014 3B42RT.

Starting about 22:00 UTC on 20 October 2014 PPS started having issues with missing input data files originating at NOAA. Informally we have been told that there is a major network issue, but have no insight on its nature or likely duration. Until this is resolved, the input data for the 3B4xRT suite of products will suffer greatly reduced volume. Currently, we are not receiving sounder data, and the IR fields only have GOES-E and -W.

Moderate rainfall was occurring around the center of Tropical Storm Adjali before it dissipated, according to data from NASA and the Japan Aerospace Exploration Agency's Global Precipitation Measurement or GPM satellites. Adjali became the first named storm of the Southwest Indian Ocean 2014/2015 cyclone season when it formed on November 16, 2014. Adjali became a strong tropical storm the next day and just two days later started to dissipate. The GPM observatory captured data on Adjali's rainfall rates on Nov. 18. GPM's Microwave Imager (GMI) instrument is similar to the Tropical Rainfall

The TRMM satellite flew over hurricane Vance on November 2014 at 0953 UTC. Rainfall derived from TRMM's Microwave Imager (TMI) data collected with that view are shown overlaid on a 1000 UTC GOES-WEST image. This analysis showed that Vance had a large area of heavy rainfall near the center of the hurricane. Some intense storms in that area were dropping rain at a rate of over 50mm/hr (almost 2 inches) per hour. Vance's power peaked late on November 3, 2014 with winds of about 95 kts (about 109 mph). Vertical wind shear had started to weaken the hurricane at the time of this view but Vance was

The hurricane season continues to be active in the eastern Pacific Ocean. A Tropical depression south of southern Mexico was upgraded to tropical storm Vance yesterday. The National Hurricane Center (NHC) predicts that Vance will become a hurricane Sunday morning making it the sixteenth hurricane of the 2014 eastern Pacific Ocean hurricane season. TRMM's Microwave imager (TMI) had a good view of the rainfall around tropical storm Vance on October 31, 2014 at 0234 UTC. An analysis of this rainfall is shown overlaid on a 0245 UTC GOES-EAST enhanced infrared image. Intense convective
