* UNTIL 545 PM EST.

* AT 500 PM EST...NATIONAL WEATHER SERVICE METEOROLOGISTS DETECTED

* OTHER LOCATIONS IN THE WARNING INCLUDE BUT ARE NOT LIMITED TO

THE IMMEDIATE DANGER OF A TORNADO IS HIGH. PEOPLE IN THE PATH OF THIS
DEVELOPING TORNADO ARE URGED TO QUICKLY PREPARE FOR ITS APPROACH.
THIS IS A DANGEROUS SITUATION! ACT NOW AS SECONDS CAN SAVE LIVES!

PRECAUTIONARY/PREPAREDNESS ACTIONS...

THE SAFEST PLACE TO BE DURING A TORNADO IS IN A STRONG BUILDING ON
THE LOWEST FLOOR...IN AN INTERIOR ROOM SUCH AS A BATHROOM OR CLOSET.
KEEP AWAY FROM WINDOWS. GET UNDER A WORKBENCH OR OTHER PIECE OF
STURDY FURNITURE. USE BLANKETS OR PILLOWS TO COVER YOUR BODY.
EVACUATE MOBILE HOMES OR VEHICLES FOR MORE SUBSTANTIAL SHELTER.

IT IS VERY RISKY TO REMAIN IN A MOBILE HOME DURING A TORNADO. MOBILE
HOMES OFFER LITTLE PROTECTION AGAINST TORNADO WINDS EVEN IF THEY ARE
TIED DOWN. IF YOU ARE IN THE PATH OF A TORNADO AND ARE IN A MOBILE
HOME...ABANDON IT FOR SAFE SHELTER. QUICKLY MOVE TO THE NEAREST
STURDY BUILDING AND GO TO AN INTERIOR ROOM ON THE LOWEST FLOOR. PUT
AS MANY WALLS BETWEEN YOU AND THE TORNADO AS POSSIBLE.

THE TORNADO WILL LIKELY BE WRAPPED IN HEAVY RAIN MAKING IT DIFFICULT
TO SEE. BE SMART AND REACT NOW!
