OTHER PREPAREDNESS INFORMATION:
NOW IS THE TIME TO CHECK YOUR EMERGENCY PLAN AND EMERGENCY SUPPLIES
KIT AND TAKE NECESSARY ACTIONS TO PROTECT YOUR FAMILY AND SECURE YOUR
HOME OR BUSINESS.
WHEN MAKING SAFETY AND PREPAREDNESS DECISIONS, DO NOT FOCUS ON THE
EXACT FORECAST TRACK SINCE HAZARDS SUCH AS FLOODING RAIN, DAMAGING
WIND GUSTS, STORM SURGE, AND TORNADOES EXTEND WELL AWAY FROM THE
CENTER OF THE STORM.
IF IN A PLACE THAT IS VULNERABLE TO HIGH WIND, SUCH AS NEAR LARGE
TREES, A MANUFACTURED HOME, UPPER FLOORS OF A HIGH-RISE BUILDING, OR
ON A BOAT, PLAN TO MOVE TO SAFE SHELTER.
IF YOU LIVE IN A PLACE PARTICULARLY VULNERABLE TO FLOODING, SUCH AS
NEAR THE OCEAN OR A LARGE INLAND LAKE, IN A LOW-LYING OR POOR
DRAINAGE AREA, IN A VALLEY, OR NEAR AN ALREADY SWOLLEN RIVER, PLAN TO
MOVE TO SAFE SHELTER ON HIGHER GROUND.
ALWAYS HEED THE ADVICE OF LOCAL OFFICIALS AND COMPLY WITH ORDERS THAT
ARE ISSUED. DO NOT NEEDLESSLY JEOPARDIZE YOUR LIFE OR THE LIVES OF
OTHERS.
WHEN SECURING YOUR PROPERTY, OUTSIDE PREPARATIONS SHOULD BE CONCLUDED
AS SOON AS POSSIBLE BEFORE CONDITIONS DETERIORATE. THE ONSET OF
STRONG GUSTY WINDS OR FLOODING CAN CAUSE CERTAIN PREPAREDNESS
ACTIVITIES TO BECOME UNSAFE.
BE SURE TO LET FRIENDS AND FAMILY MEMBERS KNOW OF YOUR INTENTIONS FOR
WEATHERING THE STORM AND YOUR WHEREABOUTS. HAVE SOMEONE LOCATED AWAY
FROM THE THREATENED AREA SERVE AS YOUR POINT OF CONTACT. SHARE VITAL
CONTACT INFORMATION WITH OTHERS. KEEP CELL PHONES HANDY AND CHARGED.
CHECK ON THOSE WHO MAY NOT BE FULLY AWARE OF THE SITUATION OR WHO ARE
UNABLE TO MAKE PERSONAL PREPARATIONS.
IF YOU ARE A VISITOR, KNOW THE NAME OF THE COUNTY OR PARISH IN WHICH
YOU ARE LOCATED AND WHERE IT IS RELATIVE TO CURRENT WATCHES AND
WARNINGS. IF STAYING AT A HOTEL, ASK THE MANAGEMENT STAFF ABOUT THEIR
ONSITE DISASTER PLAN. LISTEN FOR EVACUATION ORDERS, ESPECIALLY
PERTAINING TO AREA VISITORS.
CLOSELY MONITOR WEATHER.GOV, NOAA WEATHER RADIO AND LOCAL NEWS
OUTLETS FOR OFFICIAL STORM INFORMATION. LISTEN FOR POSSIBLE CHANGES
TO THE FORECAST.
