POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
PREPARE FOR DANGEROUS RAINFALL FLOODING HAVING POSSIBLE SIGNIFICANT
IMPACTS ACROSS THE RIO GRANDE VALLEY AND DEEP SOUTH TEXAS. POTENTIAL
IMPACTS INCLUDE:
- MODERATE RAINFALL FLOODING MAY PROMPT SEVERAL EVACUATIONS AND
RESCUES.
- ARROYOS AND LARGER CREEKS MAY QUICKLY BECOME SWOLLEN WITH SWIFT
CURRENTS AND OVERSPILL THEIR BANKS IN A FEW PLACES, ESPECIALLY
IN USUALLY VULNERABLE SPOTS. SMALL STREAMS, CREEKS, CANALS, AND
DITCHES OVERFLOW.
- FLOOD WATERS CAN ENTER SOME STRUCTURES OR WEAKEN FOUNDATIONS.
SEVERAL PLACES MAY EXPERIENCE EXPANDED AREAS OF RAPID
INUNDATION AT UNDERPASSES, LOW-LYING SPOTS, AND POOR DRAINAGE
AREAS. SOME STREETS AND PARKING LOTS TAKE ON MOVING WATER AS
STORM DRAINS AND RETENTION PONDS OVERFLOW. DRIVING CONDITIONS
BECOME HAZARDOUS. SOME ROAD AND BRIDGE CLOSURES.
* WIND:
PREPARE FOR HAZARDOUS WIND HAVING POSSIBLE LIMITED IMPACTS ACROSS DEEP
SOUTH TEXAS. POTENTIAL IMPACTS IN THIS AREA INCLUDE:
- DAMAGE TO PORCHES, AWNINGS, CARPORTS, SHEDS, AND UNANCHORED
MOBILE HOMES. UNSECURED LIGHTWEIGHT OBJECTS BLOWN ABOUT.

TO NO IMPACT IS ANTICIPATED.

AND COMMUNICATIONS DISRUPTIONS.
- LOCATIONS COULD REALIZE ROOFS PEELED OFF BUILDINGS, CHIMNEYS
TOPPLED, MOBILE HOMES PUSHED OFF FOUNDATIONS OR OVERTURNED,

ACROSS THE LOWER TEXAS COAST. POTENTIAL IMPACTS IN THIS AREA INCLUDE:

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 EXPOSED PARKING LOTS COULD
BECOME COVERED WITH SOME SURGE WATER. DRIVING CONDITIONS
DANGEROUS IN PLACES WHERE SURGE WATER COVERS THE ROAD.
