...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 200 PM CDT FOR
SOUTHERN SANTA ROSA AND SOUTHEASTERN ESCAMBIA COUNTIES...

At 1108 AM CDT, Doppler radar indicated bands of moderate to heavy 
rains continuing to lift northward off the Gulf over the warned 
area. 

Some locations that will experience flooding include...
Pensacola, Ferry Pass, Brent, West Pensacola, Ensley, Warrington,
Gonzalez, Pace, Milton, Gulf Breeze, Goulding, Bagdad, Myrtle Grove,
Oriole Beach, Navarre, Perdido Beach, Pensacola Beach, Navarre Beach,
Pea Ridge and Roeville.

Many area rain gauges over the warned area have reported upwards of 
4 to 6 inches of rain with a few localized areas seeing near 8 
inches. Most of these rains occurred overnight. Additional rainfall 
amounts of 2 to 4 inches are possible over the warned area through 
the afternoon. Due to the very wet ground conditions, additional 
heavy rains will likely lead to runoff and exacerbate flooding 
problems.   

There have been reports of a few road closures due to flooding.  

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

A Flash Flood Warning means that flooding is imminent or occurring.
If you are in the warned area move to higher ground immediately.
Residents living along streams and creeks should take immediate
precautions to protect life and property.
