...SEVERE WEATHER AWARENESS WEEK CONTINUES...

TODAY THE FOCUS IS ON FLASH FLOODING.

FLASH FLOODING IS A RAPID RISE...TYPICALLY WITHIN SIX HOURS...OF
WATER ALONG A STREAM OR IN A LOW LYING URBAN AREA. DURING THE
SUMMER...THE MOST COMMON CAUSE OF FLASH FLOODING IS DOWNPOURS
ASSOCIATED WITH THUNDERSTORMS. HOWEVER...FLASH FLOODS CAN ALSO
RESULT FROM DAM BREAKS AND HEAVY RAIN FROM TROPICAL STORMS. FLASH
FLOODING IS MEANT TO IMPLY THE THREAT IS URGENT.

EASTERN NEW YORK AND WESTERN NEW ENGLAND ARE PARTICULARLY SUSCEPTIBLE
TO FLASH FLOODS BECAUSE OF TOPOGRAPHY. HEAVY RAIN FALLING ON STEEP
TERRAIN CREATES AN IDEAL SITUATION AS WATER RAPIDLY MOVES DOWN STEEP
HILL SIDES. SOMETIMES STEEP HILL SIDES GET SO WATER LOGGED THAT THEY
SLIP AND MUD SLIDES OR DEBRIS FLOWS OCCUR. FLASH FLOODING PRESENTS A
THREAT TO THE URBAN MOTORIST TOO. UNDERPASSES CAN FILL RAPIDLY WITH
WATER. DRIVING INTO A FLOODED UNDERPASS CAN QUICKLY PUT YOU IN FIVE
OR SIX FEET OF WATER. IN 2011...TROPICAL STORM IRENE AND THE REMNANTS
OF TROPICAL STORM LEE BROUGHT WIDESPREAD FLASH FLOODING TO THE REGION.

FLASH FLOODING CAN BE DEADLY. NEVER UNDERESTIMATE THE POWER OF
WATER. HALF OF ALL FLASH FLOOD RELATED DEATHS OCCUR IN AUTOMOBILES.
TWO FEET OF FLOWING WATER WILL CAUSE MOST CARS TO FLOAT. FLOODING
HAZARDS ARE INCREASED AT NIGHT WHEN VISIBILITY IS REDUCED. THE
NATIONAL WEATHER SERVICE URGES YOU TO RESPECT ALL BARRIERS THAT
WARN OF FLOODED ROADS. TURN AROUND...DONT DROWN.

THOSE WITH INTERESTS ALONG RIVERS...CREEKS AND STREAMS SHOULD
REMAIN ALERT FOR FLASH FLOODING. CAMPERS ARE PARTICULARLY AT RISK.
A NORMALLY PLACID STREAM CAN SWELL TO A 10 FOOT DEEP RAGING RIVER
IN LESS THAN AN HOUR IF THUNDERSTORM DOWNPOURS INUNDATE AN AREA UPSTREAM.
REMEMBER...SIX INCHES OF FLOWING WATER IS OFTEN ENOUGH TO KNOCK A PERSON
OFF THEIR FEET. WHEN OUTDOORS...KEEP ALERT FOR...MUDDY RAPIDLY RISING
STREAMS...OR A LOUD ROARING SOUND UPSTREAM. IF OBSERVED...HEAD FOR
HIGHER GROUND IMEDIATELY.

NOAA WEATHER RADIO OFFERS ONE WAY TO RECEIVE IMMEDIATE RELAY OF
FLASH FLOOD WARNINGS. MANY LOCAL TELEVISION AND RADIO STATIONS
ALSO BROADCAST WEATHER ALERTS. COMPUTERS AND WIRELESS DEVICES CAN
ALSO RECEIVE WARNINGS. NATIONAL WEATHER SERVICE FLASH FLOOD WARNINGS
ARE RELAYED AS WIRELESS EMERGENCY ALERTS TO NEWER PHONES BY FEMA.
