Deadly Flooding Gulf Coast Rainfall Measured By NASA's IMERG

An extremely severe rainfall event hit the states of Louisiana and southern Mississippi when a very slow moving low pressure system continuously pulled tropical moisture from the Gulf Of Mexico. Measurements by the GPM core observatory satellite showed that rainfall intensity within the low pressure system actually increased on August 12, 2016 as the low settled over southeastern Louisiana. At least 4 people have died in record flooding after the unusually heavy rainfall starting falling last week. More than 27 inches (686 mm) of rain have been reported in the area. This is the second time

GPM Looks at Historic Flooding from Slow-Moving Maryland Storms

NASA analyzed rainfall data from slow-moving storms that triggered flash floods over parts of central Maryland and caused devastating flooding in historic Ellicott City, Maryland. A slow-moving line of heavy thunderstorms dumped as much as 6 to 7 inches of rain in about two hours' time during the evening of Saturday, July 30, over parts of Howard County in central Maryland, resulting in severe local flash flooding. The hardest hit area was the historic town of Ellicott City, where two people were trapped in their cars and drowned. The town suffered substantial damage to many buildings

IMERG Measures West Virginia's Deadly Flooding Rainfall

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

Slow-moving Frontal System Triggers Storms, Flooding Across Ohio Valley

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

GPM IMERG Sees Flooding in France

In June 2016, a slow-moving weather system unleashed several days of heavy downpours on western Europe, pushing the Seine River to heights not seen in 34 years. With the Seine’s water levels 6.1 meters (20 feet) above normal in Paris, flood waters knocked out electricity for thousands of people, interrupted road and rail traffic, shut down schools, and caused an estimated 1 billion euros of damage. During the worst of the flooding, the world’s most visited museum, the Louvre, closed as employees scrambled to move artwork out of basement areas that were at risk of flooding. The map above

Rainfall Causes Texas and Oklahoma Flooding

Continuing heavy rain has resulted in dangerous flooding conditions from Oklahoma through eastern Texas. The Brazos, Trinity and Colorado Rivers in Southeastern Texas are at or above flood stage. Flooding resulted in the deaths of at least 6 people in Texas during the past week. Governor Greg Abbott declared a state of disaster in 31 Texas counties. Over 20 inches of rainfall were reported in some areas since May 30, 2016. Parts of Georgia and the Carolinas were flooded by very slow moving tropical depression Bonnie. This estimate of rainfall totals from May 27, 2016 to June 2, 2016 was made

Deadly Flooding Rainfall Over Texas And Tropical Storm Bonnie Measured From Space

Heavy rainfall caused deadly flooding in southeastern Texas. At least 4 people have been killed and continuing rainfall is expected to cause historic flooding in that area. Meanwhile, dissipating Tropical storm Bonnie is soaking the South Carolina coast, southeastern North Carolina and eastern Georgia on this Memorial Day weekend. Some flooding is expected as dissipating tropical storm Bonnie's rainfall moves northeastward along the coast. This analysis of liquid precipitation from space was accomplished by using merged satellite rainfall data from the TRMM Multi-satellite Precipitation

GPM Measures Deadly Flooding Rainfall

Over the past week extreme rainfall caused flooding that resulted in the deaths of four in Haiti and the evacuation of over 2500 people in the Dominican Republic. The GPM core observatory satellite saw a line of heavy rainfall on the eastern side of the Dominican Republic when it flew over on May 8, 2016 at 0428 UTC. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments collected data that were used to estimate rainfall. This precipitation is shown on a top-down satellite view. Powerful storms were measured dropping rain at a rate of almost 300 mm (11.8 inches)

Torrential Rain Over South Measured From Space

Extremely heavy rain fell over the southern United States during the past week. A slow moving area of low pressure pumped moisture from the Gulf Of Mexico causing torrential rain that resulted in wide spread flooding in states from Texas to Tennessee. Over 24 inches of rain was reported in Monroe, Louisiana. Over 4,958 homes in Louisiana were reportedly damaged by the flooding. Strong winds accompanying intense thunderstorms also toppled trees in Mississippi and Louisiana. A simulated 3-D animation of NASA merged satellite rainfall analysis (TMPA) using data collected from March 7-14, 2016

GPM Views Severe Weather And Heavy Rain in the U.S.

The GPM satellite flew above storms in the southwestern United States this morning (March 9, 2016) at 1011 UTC (5:11 CST). Severe weather has been moving slowly through this area for the past couple days. Two tornadoes developed in north central Texas yesterday morning (March 8, 2016). This morning rain was measured by GPM's Dual-Frequency Precipitation Radar (DPR) instrument falling at the extreme rate of over 148 mm (5.8 inches) in one powerful storm over eastern Texas. GPM's radar (DPR Ku Band) found that a few thunderstorm tops in this area were reaching altitudes above 13.7 km (8.5 miles)
