...PENNSYLVANIA SEVERE WEATHER AWARENESS WEEK...

THIS IS SEVERE WEATHER AWARENESS WEEK IN PENNSYLVANIA.

NOW IS THE TIME TO PREPARE FOR THE UPCOMING SEVERE WEATHER SEASON.

WE ARE COVERING A DIFFERENT SAFETY TOPIC EACH DAY OF THIS WEEK.

OUR SEVERE WEATHER AND WEATHER SAFETY TOPIC FOR TODAY IS...
FLASH FLOODING AND FLASH FLOOD SAFETY.

MORE PEOPLE ARE KILLED BY FLASH FLOODS THAN BY OTHER STORM-RELATED
WEATHER HAZARDS. UNFORTUNATELY...MOST PEOPLE SUCCUMB TO FLOODING
AFTER THEY DRIVE THEIR AUTOMOBILES INTO FLOODED ROADWAYS AND ARE
SUBSEQUENTLY SWEPT AWAY TO THEIR DEATHS.

IF YOU ENCOUNTER A FLOODED ROADWAY...TURN AROUND...DON`T DROWN!
FIND ANOTHER ROUTE...IT COULD SAVE YOUR LIFE! MANY PEOPLE LOSE
THEIR LIVES BY NOT ADHERING TO THIS SIMPLE RULE...
TURN AROUND...DON`T DROWN!

WHAT IS A FLASH FLOOD?

A FLASH FLOOD IS A RAPID FLOOD.
DURING A FLASH FLOOD...A STREAM OR CREEK WILL RISE RAPIDLY AND
CREST GENERALLY WITHIN A FEW HOURS OF THE START OF THE HEAVY RAIN.
 FLASH FLOODS ARE SO DANGEROUS BECAUSE THE WATERS RISE SO
QUICKLY THAT THEY CAN CATCH PEOPLE OFF GUARD AND TRAP THEM IN
PRECARIOUS SITUATIONS. THIS IS WHY THE NATIONAL WEATHER SERVICE
CONSTANTLY MONITORS RAINFALL USING RAIN GAUGES AND RADAR
ESTIMATES...AS WELL AS MONITORING STREAM AND CREEK LEVELS
USING AUTOMATED RIVER GAUGES AND LOCAL SPOTTERS. YOUR NATIONAL
WEATHER SERVICE WILL ISSUE FLASH FLOOD WATCHES AND WARNINGS
TO HELP ALERT YOU TO EXPECTED FLOOD DANGERS.

WHAT CAUSES FLASH FLOODS?

FLASH FLOODS ARE CAUSED WHEN VERY HEAVY RAINFALL...USUALLY FROM
SLOW-MOVING THUNDERSTORMS...OVERWHELMS THE NATURAL OR MAN-MADE
DRAINAGE SYSTEMS. STREAMS...CREEKS AND SMALLER RIVERS ARE MOST
VULNERABLE TO FLASH FLOODING. FLASH FLOODING OCCURS IN URBAN
AREAS AS WELL AS IN RURAL AREAS.

WHAT DOES A FLASH FLOOD WATCH MEAN?

A FLASH FLOOD WATCH MEANS THAT THE POTENTIAL EXISTS FOR FLASH
FLOODING TO OCCUR ON ANY STREAM...CREEK OR SMALL RIVER. THE
WATCH DOES NOT MEAN THAT FLOODING IS IMMINENT OR OCCURRING.
IT JUST MEANS THAT IT IS A POSSIBILITY.

WHAT YOU SHOULD DO WHEN A FLASH FLOOD WATCH IS ISSUED...

BE PREPARED TO TAKE QUICK ACTION TO PROTECT YOURSELF BY MOVING
 TO HIGHER GROUND IF YOU ARE NEAR A WATERWAY. WATCH WATER LEVELS
CAREFULLY AND BE READY TO EVACUATE AT ANY MOMENT. IF YOU ARE
TRAVELING DURING A FLASH FLOOD WATCH...BE ALERT FOR SIGNS OF
FLASH FLOODING...ESPECIALLY AT NIGHT WHEN IT CAN BE DIFFICULT
TO SEE A FLOODED ROADWAY. BE VERY CAREFUL IF DRIVING THROUGH
FLOOD PRONE AREAS...AND IF YOU ENCOUNTER A FLOODED ROADWAY...
TURN AROUND...DON`T DROWN. FIND AN ALTERNATE ROUTE. IT COULD
 SAVE YOUR LIFE!

WHAT DOES A FLASH FLOOD WARNING MEAN?

A FLASH FLOOD WARNING MEANS RAPID LIFE-THREATENING FLOODING IS
OCCURRING...OR WILL BEGIN VERY SOON. A WARNING LETS YOU KNOW
THAT HEAVY RAIN WILL CAUSE THE WATER TO RISE AND OVERFLOW THE
BANKS OF THE WATERWAYS NEARBY. A FLASH FLOOD WARNING CAN ALSO
 BE PROMPTED BY LEVEE AND DAM FAILURES. YOU NEED TO TAKE ACTION
 IMMEDIATELY TO PROTECT YOUR LIFE AND PROPERTY IF YOU ARE IN
THE DANGER AREA.

WHAT SHOULD YOU DO WHEN A FLASH FLOOD WARNING IS ISSUED?

MOVE UP TO HIGHER GROUND IMMEDIATELY AND GET OUT OF THE DANGER
 AREA. NEVER DRIVE ACROSS BRIDGES COVERED WITH WATER...OR THROUGH
AREAS WHERE WATER COVERS THE ROADWAY.  MOST CARS WILL FLOAT IN
JUST 16 TO 18 INCHES OF WATER. IF RISING WATER CAPTURES YOUR
AUTOMOBILE...IT COULD EASILY SWEEP YOU AWAY. BE ESPECIALLY
CAUTIOUS AT NIGHT...WHEN IT IS HARDER TO RECOGNIZE THAT AN AREA
 MAY BE FLOODED.
