Precipitation Processing System (PPS) servers will be down for extended maintenance from Tuesday, September 22nd through Thursday September 24th. During this time the PPS websites, the PMM Publisher API, and the GPM research data server (arthurhou) will be unavailable. The GPM near real-time server (jsimpson) and satellite data collection will not be affected. Click here to learn more.

GPM IMERG Observes Rainfall from Tornado-spawning Storms in the Southern U.S.

Download video (right-click -> Save As). Credit: Jason West (KBR / NASA GSFC) From Sunday, April 12th, 2020 into Monday the 13th, a series of powerful thunderstorms developed across the southern U.S., bringing heavy rainfall and spawning several destructive tornadoes. This animation shows rainfall estimates for the region for April 11th - 13th derived from NASA's Integrated Multi-satellite Retrievals for GPM (IMERG) data product, along with NOAA tornado reports (red triangles).

GPM Catches Line of Strong Storms Responsible For Tornadoes in Eastern U.S.

Yesterday, Sunday April 15th, a line of strong storms at one point stretched from the Florida Straits below the Florida Keys all the way up the East Coast and into Ohio. Many of the storms were strong with wide spread reports of wind damage from north Florida up through the Carolinas and into central Virginia. Among these were several reports of tornadoes from Florida to Virginia. The most significant were an EF-2 tornado that stuck Greensboro, NC, killing one person, and a tornado near Lynchburg in Amherst County Virginia that injured 8 people. GPM captured this image of the advancing line of

Severe Midwest Storms Probed By GPM Satellite

The GPM core observatory satellite flew over stormy weather in the Midwest on Saturday February 24, 2018 at 1610 UTC (10:10 AM CST). Floods and very severe thunderstorms were developing with this slow moving storm complex. Later in the day tornadoes within these storms caused destruction and injuries in the states of Kentucky, Arkansas, Missouri and Tennessee. Tornadoes and flooding were blamed for at least four fatalities. Kentucky was particularly hard hit with Saturday evening tornadoes moving through southwestern Kentucky causing multiple injuries and at least three deaths. GPM's microwave

GPM Radar Shows Tornado Spawning Thunderstorms

Tornadoes were reported yesterday evening in Illinois, Indiana and Ohio. At least nine twisters were reported between 1:40 PM EST and 6:22 EST (1840 - 2322 utc). This unsettled weather caused many customers to lose electric power in northern Ohio. One powerful storm injured eight people in the northern Ohio town of Celina. The severe weather may also be the cause of two deaths in Erie Pennsylvania. The GPM core observatory satellite had an exceptional view of the extreme weather in northeastern Ohio on Sunday November 5, 2017 at 6:12 PM EST ( 2312 UTC). The GPM satellite scanned tornado

Heavy Downpours Cause Flooding In The Midwest

Heavy rain has resulted in significant flooding in the Midwest during the past week. Water flowing into the Fox River in northeastern Illinois caused serious flooding in that area. Central Indiana and central Ohio have also had remarkable flooding. NASA's Integrated Multi-satelliE Retrievals for GPM (IMERG) data were used to show estimates of rainfall accumulation in the Midwest during the period from July 7-14, 2017. This analysis indicates that parts of Wisconsin, Illinois, Indiana and Ohio had the highest rainfall totals during the period with over 6 inches (152.4 mm) of rain being seen in

Tornado Spawning Storms Examined By GPM Satellite

On Wednesday May 24, 2017 severe weather affected a large area of the eastern United States. Tornadoes were reported in Florida, Georgia, South Carolina, North Carolina and Ohio. The GPM core observatory satellite flew above a line of tornado spawning storms that were moving through the Florida panhandle on May 24, 2017 at 10:26 AM EDT ( 1426 UTC). GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments collected data showing that very heavy downpours were accompanying some of these storms. The violent storms moving through the Southeast were strong but GPM's

Deadly Tornadoes & Flooding Hits The Southeast

Severe thunderstorms spawned tornadoes and generated flooding rainfall over the Southeast on Monday evening. At least twelve tornadoes were reported with twisters spotted in Mississippi, Alabama and Georgia. Four deaths in Alabama and one in Florida have been blamed on this violent weather. Total rainfall was measured from December 30, 2016 through early January 3, 2017 using precipitation estimates from NASA's Integrated Multi-satelliE Retrievals for GPM (IMERG) data. IMERG data are produced using data from the satellites in the GPM Constellation, and is calibrated with measurements from the

GPM Sees Deadly Tornadic Storms Moving Through The Southeast

On Tuesday evening through Wednesday morning tornadoes formed along a squall line in advance of a cold front that moved through the Southeast. Over three dozen tornadoes were reported with sightings occurring in Louisiana, Alabama, Mississippi, Tennessee and Alabama. Tornadoes caused the deaths of a least five people in northern Alabama. Storms also took the the lives of two people in Tennessee. This Rainfall may provide some relief to drought ridden eastern Tennessee where destructive wildfires have been occurring. Some storms were accompanied with hail, strong winds and intense showers. Golf

Severe Weather In Tornado Alley And Eastward (May 2nd Update)

Severe spring thunderstorms frequently spawned tornadoes from the Gulf Coast north and eastward during the past seven days. From April 25 to May 2, 2016 there were over 67 tornadoes in the United States reported to the National Oceanic and Atmospheric Administration (NOAA). Many of these tornadoes were located in an area that includes the states of Texas, Oklahoma, Kansas, and Nebraska. This area of the Great Plains has been labeled Tornado Alley due to the many tornadoes that occur there this time of year. Gulf moisture clashing with frontal systems moving over the United States provided much

Severe Weather In Tornado Alley And Eastward

Severe spring thunderstorms frequently spawned tornadoes from the Gulf Coast north and eastward during the past week. Gulf moisture clashing with frontal systems moving over the United States provided much of the fuel for intense showers and severe thunderstorms. Flash flooding was often the result of the sudden onset of extremely heavy rainfall. Over 305 mm (12 inches) of rain was reported in southern Mississippi in a few hours one morning on April 28, 2016. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) data were used to estimate the amount of rain that fell from April 22-29
