The National Weather Service in Melbourne has issued a
* Flash Flood Warning for...
Central Brevard County in Florida...
* Until 1130 PM EDT
* At 824 PM EDT, Doppler radar and automated rain gauges continue to
indicate heavy rain falling from persistent rain bands across much
of Brevard County. Measured rainfall amounts up to 4 to 6 inches
have already occurred from Satellite Beach and Melbourne northward
through Cape Canaveral, Cocoa and Merritt Island, and additional
heavy rainfall up to 2 to 3 inches will be possible across this
region. Farther south, amounts will not be as heavy, but moderate
rain combined with amounts up to 8 to 10 inches that have already
fallen from West Melbourne area, as well as Melbourne Beach
southward through Floridana Beach will continue flooding issues.
This heavy rainfall will lead to flash flooding, with roadways
becoming impassable and water potentially entering some homes.
* Some locations that will experience flooding include...
West Melbourne, Melbourne, Malabar, Satellite Beach, Melbourne
Beach, Floridana Beach, Merritt Island and Cocoa.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles. Be especially cautious at night when it is
harder to recognize the dangers of flooding.
Please report flooding to your local law enforcement agency when you
can do so safely.
A Flash Flood Warning means that flooding is imminent or occurring.
Residents living along streams and creeks should take immediate
precautions to protect life and property.
