PUBLIC INFORMATION STATEMENT  
NATIONAL WEATHER SERVICE SHREVEPORT LA  
609 AM CST THU MAR 5 2015  
   
..CONTINUING SEVERE WEATHER AWARENESS WEEK IN TEXAS...OKLAHOMA
 
 
LOUISIANA...AND ARKANSAS...  
 
TODAY'S TOPIC IS FLASH FLOOD SAFETY...  
 
AS PART OF SEVERE WEATHER AWARENESS WEEK...THE NATIONAL WEATHER  
SERVICE WANTS YOU TO BE AWARE OF THE DANGERS OF FLASH FLOODING.  
 
A FLASH FLOOD IS A RAPID RISE OF WATER ALONG A STREAM...OR IN A LOW  
LYING URBAN AREA. FLASH FLOODING CAN RESULT FROM SLOW MOVING  
THUNDERSTORMS...FROM NUMEROUS THUNDERSTORMS WHICH DEVELOP REPEATEDLY  
OVER THE SAME AREA...AND FROM HEAVY RAINS ASSOCIATED WITH TROPICAL  
CYCLONES. THESE FLOODS MAY DEVELOP WITHIN MINUTES...DEPENDING ON THE  
INTENSITY OF RAINFALL...THE TOPOGRAPHY...SOIL CONDITIONS...AND GROUND  
COVER.  
 
FEW PEOPLE REALIZE THE TRUE POWER OF WATER. RAPIDLY MOVING FLOOD  
WATERS ONLY SIX INCHES DEEP CAN KNOCK AN ADULT OFF THEIR FEET. TWO  
FEET OF WATER CAN LIFT APPROXIMATELY 3000 POUNDS...WHICH IS THE  
WEIGHT OF AN AVERAGE SIZED VEHICLE. VEHICLES CROSSING A FLOODED  
ROADWAY CAN LOSE TRACTION WITH THE ROAD...ACTUALLY FLOATING IN SOME  
CASES. IN SOME CASES...WATER CAN ERODE THE EARTH UNDERNEATH A ROAD...  
CAUSING IT TO WASH OUT. IF A VEHICLE BECOMES OVERTURNED...IT CAN FILL  
WITH WATER...ENDANGERING THE LIVES OF ITS OCCUPANTS. FLASH FLOOD  
STATISTICS INDICATE THAT HALF OF THE ANNUAL FLOOD FATALITIES ARE  
VEHICLE RELATED.  
 
WHEN FLASH FLOODS OCCUR IN RURAL AREAS...PEOPLE WHO ENJOY HUNTING...  
CAMPING AND FISHING NEED TO STAY AWAY FROM STREAMS IF STRONG  
THUNDERSTORMS HAVE OCCURRED. WATER IN STREAMS CAN RISE OVER TEN FEET  
IN LESS THAN AN HOUR WITH THE HEAVY RAINFALL.  
 
SO HOW CAN WE STAY SAFE FROM THE DANGERS ASSOCIATED WITH FLASH  
FLOODING?  
 
MONITOR WEATHER RADIO AND PAY CLOSE ATTENTION TO FLASH FLOOD  
WARNINGS ISSUED BY THE NATIONAL WEATHER SERVICE.  
 
BE ESPECIALLY CAUTIOUS AT NIGHT WHEN IT IS MORE DIFFICULT TO  
RECOGNIZE THE DANGERS OF FLASH FLOODING.  
 
AVOID LOW LYING AREAS THAT ARE PRONE TO FLOODING. DO NOT CAMP OR PARK  
YOUR VEHICLE ALONG STREAMS AND WASHES. IF YOUR VEHICLE IS SUDDENLY  
CAUGHT IN RISING WATER...LEAVE IT IMMEDIATELY AND MOVE TO HIGHER  
GROUND.  
 
LASTLY...NEVER ATTEMPT TO CROSS AREAS WHERE WATER COVERS THE ROAD.  
REMEMBER THE FIRST SAFETY RULE OF FLASH FLOODING...TURN  
AROUND...DO NOT DROWN.
