ACROSS THE MATAGORDA BAY AREA. POTENTIAL IMPACTS IN THIS AREA

IMMEDIATE SHORELINES AND IN LOW-LYING SPOTS, OR IN AREAS
FARTHER INLAND NEAR WHERE HIGHER SURGE WATERS MOVE ASHORE.
- SECTIONS OF NEAR-SHORE ROADS AND PARKING LOTS BECOME OVERSPREAD
WITH SURGE WATER. DRIVING CONDITIONS DANGEROUS IN PLACES WHERE
SURGE WATER COVERS THE ROAD.
- MODERATE BEACH EROSION. HEAVY SURF ALSO BREACHING DUNES, MAINLY

AND PIERS. A FEW SMALL CRAFT BROKEN AWAY FROM MOORINGS.
ELSEWHERE ACROSS SOUTHEAST TEXAS, LITTLE TO NO IMPACT IS ANTICIPATED.
* TORNADOES:
PREPARE FOR A TORNADO EVENT HAVING POSSIBLE LIMITED IMPACTS ACROSS
THE MATAGORDA BAY AREA. POTENTIAL IMPACTS INCLUDE:
- THE OCCURRENCE OF ISOLATED TORNADOES CAN HINDER THE EXECUTION
OF EMERGENCY PLANS DURING TROPICAL EVENTS.

AND COMMUNICATIONS DISRUPTIONS.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
LISTEN TO LOCAL OFFICIAL FOR RECOMMENDED PREPAREDNESS ACTIONS,
INCLUDING POSSIBLE EVACUATION. IF ORDERED TO EVACUATE, DO SO
IMMEDIATELY.
FOR THOSE NOT UNDER EVACUATION ORDERS, ASSESS THE RISK FROM WIND,
FALLING TREES, AND FLOODING AT YOUR LOCATION. IF YOU DECIDE TO MOVE,
RELOCATE TO A SAFER LOCATION NEARBY. IF YOU DO NOT RELOCATE,
HELP KEEP ROADWAYS OPEN FOR THOSE UNDER EVACUATION ORDERS.
* 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.
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.
CLOSELY MONITOR WEATHER.GOV, NOAA WEATHER RADIO AND LOCAL NEWS
OUTLETS FOR OFFICIAL STORM INFORMATION. LISTEN FOR POSSIBLE CHANGES
TO THE FORECAST.
