A rare and extreme weather pattern has produced obscene and devastating amounts of rainfall from Mobile, Alabama to Pensacola, Florida.  Up to 2 feet of rain fell in the last 24 hours in isolated locations in this region.

Pensacola and Mobile both officially received over 11 inches of rain, the third highest daily totals dating back over 130 years, according to Capital_Climate on Twitter.

Nearby, doppler radar estimates totals over 20 inches.

The Escambia Sheriff’s Office in Pensacola logged over 26 inches according to WeatherBug.

Remarkably, these rainfall totals bested scores of moisture-laden tropical storms and hurricanes that have come through this region over the last century.

The impacts of the flash flooding have been devastating, as the flood waters have taken out bridges and formed destructive sink holes. The video and pictures are not to be believed…

The exceptional rainfall totals reflect a rare weather pattern forming a massive tilted “S” across the U.S (see flow pattern in center panel and satellite image in right panel, below).

Unusually intense high pressure over Canada and low pressure over the central U.S.  (see left panel in image above) have formed an extreme pressure couplet around which the weather has flowed (center and right panels).  Along the southern flank of this massive weather system, near-historic quantities of moisture has been drawn out of the Gulf of Mexico – setting the stage for the extraordinary rain totals.
