WEATHER SERVICE RALEIGH NC MON MAY 22 2006...

NORTH CAROLINA HURRICANE AWARENESS WEEK...

THIS WEEK HAS BEEN DECLARED NORTH CAROLINA'S HURRICANE AWARENESS WEEK FOR 2006. ALL WEEK LONG THE NATIONAL WEATHER SERVICE WILL BE ISSUING INFORMATIVE MESSAGES TO HELP YOU PREPARE FOR HURRICANE SEASON. EACH DAY WE WILL COVER A DIFFERENT TOPIC. TODAY WE WILL TALK ABOUT TORNADOES IN TROPICAL SYSTEMS.
NEARLY ALL TROPICAL STORM AND HURRICANES PRODUCE TORNADOES WHICH ADD TO THE STORMS DESTRUCTION.

IN 2004 AROUND 45 TORNADOES TOUCHED DOWN IN NORTH CAROLINA AS THE REMNANTS OF BONNIE...CHARLEY... GASTON...FRANCES AND IVAN FROM THE COAST TO THE MOUNTAINS. NO REGION OF THE STATE HAS AVOIDED TORNADOES. THREE PEOPLE DIED DURING THE 2004 TROPICAL SEASON AS A TORNADO RIPPED APART THEIR MOBILE HOME IN PENDER COUNTY DURING TROPICAL STORM BONNIE. BOTH HURRICANES FLOYD AND FRAN ALSO PRODUCED NUMEROUS TORNADOES DESTROYING SEVERAL HOMES. TORNADOES ARE TYPICALLY THE FIRST THREAT NORTH CAROLINA FACES FROM HURRICANES AS THE OUTER RAIN BANDS PUSH INLAND. THE TORNADO THREAT PRECEDES THE HURRICANE LANDFALL BY MANY HOURS. AS THE FIRST OUTER RAIN BANDS FROM THE SYSTEM MOVE INLAND WELL AWAY FROM THE CENTER OF CIRCULATION...TORNADOES USUALLY OCCUR.

MOST TORNADOES IN TROPICAL SYSTEMS OCCUR NORTH AND EAST OF THE PRIMARY CIRCULATION OR EYE. THIS REGION OF THE STORM HAS THE MOST SHEAR AND FAVORABLE WIND PROFILES NECESSARY FOR TORNADO DEVELOPMENT. SINCE TROPICAL SQUALLS TYPICALLY MOVE AT 40 TO 60 MPH TORNADOES EMBEDDED IN THESE BANDS HIT QUICKLY AND WITH LITTLE WARNING. TROPICAL TORNADOES DEVELOP IN JUST A MATTER OF A FEW MINUTES AND FORECASTERS WORK DILIGENTLY TO TRACK AND ANTICIPATE WHICH CIRCULATIONS WILL BECOME TORNADIC. MOST TORNADOES ASSOCIATED WITH THE OUTER BANDS OF A TROPICAL SYSTEM ARE RELATIVELY WEAK...HOWEVER THESE WEAK TORNADOES STILL PACK WINDS OF 100 TO 120 MPH. THIS IS ENOUGH TO DEMOLISH MOBILE HOMES...DAMAGES HOUSES AND IN SOME CASES FLIP CARS OVER. NO MOBILE HOME OR MANUFACTURED HOME IS SAFE IN HURRICANE FORCE OR TORNADO WINDS. RESIDENTS IN MOBILE HOMES SHOULD EVACUATE TO A SAFER STRUCTURE WHICH MAY INCLUDE THE HOME OF ANOTHER FAMILY MEMBER OR FRIEND. IF SHELTERING IN A STURDY BUILDING... YOU WANT TO TAKE SHELTER ON THE LOWEST FLOOR IN A BATHROOM OR CLOSET WHEN HIGH WINDS THREATEN.

WHEN A TROPICAL SYSTEM IS FORECAST TO MOVE INTO THE AREA YOU CAN EXPECT TORNADOES. REALIZE THE TROPICAL SYSTEM CAN MAKE LANDFALL IN ANOTHER STATE OTHER THAN NORTH CAROLINA AND STILL POSE A SERIOUS TORNADO THREAT TO YOUR HOME AND FAMILY. YOU SHOULD ALWAYS MONITOR LOCAL FORECASTS PAYING ATTENTION TO TORNADO OUTLOOKS WATCHES AND WARNINGS ISSUED WELL IN ADVANCE OF THE TROPICAL SYSTEM.
