Heavy Rainfall Across the U.S. Measured from Space

For close to two weeks the combination of a nearly stationary front and tropical moisture caused almost continuous precipitation over much of the Mid-Atlantic. Record amounts of rain fell over the eastern United States with over a foot of rain reported in some parts of the Mid-Atlantic. The excessive rain led to flooding along several rivers including the Potomac river. This image shows anomalous rainfall for the period from May 11-20, 2018. This analysis used climatology data that were based on measurements by the Tropical Rainfall Measuring Mission (TRMM) satellite from 1997- 2015. The TRMM

Extreme U.S. Rainfall Analyzed With IMERG Data

Tornadoes have accompanied severe weather over the United States almost daily during the past week. Severe storms spawned tornadoes from Texas and Oklahoma eastward through Mississippi. Upper Midwest states such Illinois, Indiana and Kentucky were also visited by tornadoes. Extreme rainfall caused deadly flooding in Missouri. More than a dozen people in the Midwest and South have been reported killed by tornadoes or flooding. The same weather system is spreading severe storms through East and Northeastern states today. NASA's Integrated Multi-satelliE Retrievals for GPM (IMERG) data were used

Precipitation Measured from U.S. Winter Storm

Freezing rain and snow from a winter storm have caused power outages and deaths from the southeastern to the northeastern United States. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (TMPA) at the NASA Goddard Space Flight Center is used to estimate precipitation for much of the globe. TMPA (liquid) precipitation totals (mm) are shown for the week from February 7-14, 2014 when a winter storm was moving through the area. Snow depths can be expected to be 10 to 12 times that for the same amount of rainfall. Liquid precipitation estimates of over 110mm (~4.3 inches) are
