Florida Gulf Coast Region Experiences "Historic" Rainfall Event

Animation Loop: Florida Gulfcoast Rainfall accumulation April 29 & 30, 2014

This animation loop shows satellite-estimated accumulation of rainfall from midnight Central time on Tuesday, April 29 to 2 PM Central time Wednesday, April 30 in the Gulf Coast region.

April 30, 2014 - A very strong and slow-moving springtime storm pulled tremendous amounts of moist air from over the Gulf of Mexico into the Eastern United States this week, producing very intense and long-lasting rainfall that resulted in devastating floods. The subsequent widespread flooding produced sinkholes (some very large and deep), cut roads in half and necessitated human water rescues and is cited as the cause for one confirmed fatality.

Pensacola's official airport rain gauge measured 5.68 inches in a single hour before it failed around 10 p.m. Tuesday night. Official measurements for the total rainfall from this storm were also incomplete due to failed gauges, but radar estimates by the NWS and STAR's own hydroestimator measurements concur that the total for the event was around 24", which is comparable to the rain output from a hurricane, and is itself approximately a 1 in 25 year event. 5.68 inches in a single hour was characterized by the National Weather Service as a once in 200 year to once in 500 year event.
