Flooding in West Virginia

The state of West Virginia suffered nearly 30 people killed due to extreme, rapid flooding starting on Thursday of last week. Beginning on Wednesday, a set of severe storms erupted in the central US near Chicago, at the northwest corner of this gif, and the disturbance traveled southeast until it reached the mountains in West Virginia and dumped its remaining moisture on that landscape. Some meteorologists classified this event as a low-grade derecho, a type of destructive straight-line storms that can cover large distances.

The rainfall in this event has been classified as a “thousand year storm” for the worst hit areas in West Virginia, with nearly 30 centimeters (almost 1 foot) of rain falling in the space of a few hours. A few years ago, the US launched the key satellite in the Global Precipitation Measurement system, a set of satellites that use radar to penetrate clouds and actively measure the amount of moisture falling on the surface. This Gif shows data from the days before and after that storm strike in West Virginia. You can actually see the rainfall path begin and then flare up suddenly as it hits that state. The largest rainfall totals on this map measure 32 centimeters (12.6 inches).

Rains and flooding

Over the past week, several areas in the Midwestern U.S., in a swath stretching from Minnesota to Texas, have received torrential rains and are now dealing with flooding.

This plot was created by NASA using data from the Tropical Rainfall Measuring Mission (TRMM) satellite and it shows the precipitation received in the last week for an area at the heart of this downpour.

For scale, the average monthly precipitation for areas in Iowa during the summer is about 110 mm (~4.5 inches) of rain, so the areas in green received their entire monthly precipitation in a week, while areas in yellow and red received over 2 months of precipitation in a week.
