GPM Looks at Rainfall in Remnants of Songda Over Pacific NW

The Global Precipitation Measurement mission or GPM core satellite saw heavy rain with rates of around 50 mm/hr (~2 inches/hr shown in dark red) in the front that absorbed the remnants of former northwestern Pacific Ocean Typhoon Songda. These images were created from data taken on Saturday, Oct. 15 as the front was affecting the U.S. Pacific Northwest. The rain is depicted in red and green areas, indicating heavy, moderate and light rain, respectively. Images produced by Jacob Reed (Telophase/NASA GSFC) and caption by Rob Gutro (GSFC)

Northwest's Extreme Rainfall Checked By IMERG

During the past week moisture from the tropics has been pumped into the Pacific Northwest by the "Pineapple Express". Resulting extreme rainfall has led to widespread flooding and landslides. The continued "training" of rainfall into the area has caused flooding in the Portland, Oregon area with at least one death reported. Western Washington is also on flood alert due to the deluge. Rainfall that occurred during the past week (December 2-9, 2015) was measured with data from NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG). IMERG found that many areas from northern California
