POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
PREPARE FOR LIFE-THREATENING RAINFALL FLOODING HAVING POSSIBLE
EXTENSIVE IMPACTS ACROSS SOUTHWEST LOUISIANA AND SOUTHEAST TEXAS.
POTENTIAL IMPACTS INCLUDE:
- MAJOR RAINFALL FLOODING MAY PROMPT MANY EVACUATIONS AND RESCUES.
- RIVERS AND TRIBUTARIES MAY RAPIDLY OVERFLOW THEIR BANKS IN
MULTIPLE PLACES. SMALL STREAMS, CREEKS, CANALS, AND DITCHES MAY
BECOME DANGEROUS RIVERS. FLOOD CONTROL SYSTEMS AND BARRIERS MAY
BECOME STRESSED.
- FLOOD WATERS CAN ENTER MANY STRUCTURES WITHIN MULTIPLE
COMMUNITIES, SOME STRUCTURES BECOMING UNINHABITABLE OR WASHED
AWAY. MANY PLACES WHERE FLOOD WATERS MAY COVER ESCAPE ROUTES.
STREETS AND PARKING LOTS BECOME RIVERS OF MOVING WATER WITH
UNDERPASSES SUBMERGED. DRIVING CONDITIONS BECOME DANGEROUS.
MANY ROAD AND BRIDGE CLOSURES WITH SOME WEAKENED OR WASHED OUT.
* SURGE:
PREPARE FOR LIFE-THREATENING SURGE HAVING POSSIBLE SIGNIFICANT
IMPACTS ACROSS THE COASTLINE FROM RUTHERFORD BEACH WESTWARD. POTENTIAL IMPACTS IN
THIS AREA INCLUDE:
- AREAS OF INUNDATION WITH STORM SURGE FLOODING ACCENTUATED BY
WAVES. DAMAGE TO NON-ELEVATED STRUCTURES IS POSSIBLE.
- SECTIONS OF ESCAPE ROUTES AND SECONDARY ROADS BECOME WEAKENED
OR WASHED OUT, ESPECIALLY IN USUALLY VULNERABLE LOW SPOTS.

CRAFT BROKEN AWAY FROM MOORINGS, ESPECIALLY IN UNPROTECTED
ANCHORAGES.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
LISTEN TO LOCAL OFFICIAL FOR RECOMMENDED PREPAREDNESS ACTIONS, INCLUDING POSSIBLE EVACUATION. IF ORDERED TO
EVACUATE, DO SO IMMEDIATELY.
* 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 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.
