SITUATION OVERVIEW
------------------
AT 10 AM CDT, TROPICAL STORM IDA CONTINUES TO MOVE NORTH AT 9 MPH OVER
SOUTHWESTERN MISSISSIPPI. MINIMUM CENTRAL PRESSURE HAS INCREASED TO
996 MB.
IDA IS EXPECTED TO BRING ADDITIONAL RAINFALL AMOUNTS OF 3-6 INCHES,
WITH HIGHER ISOLATED RAINFALL AMOUNTS. THIS IS LIKELY TO RESULT IN
FLASH, URBAN, SMALL STREAM, AND RIVER FLOODING OVER PORTIONS OF OUR
AREA.
THE TORNADO THREAT WILL CONTINUE ACROSS SOUTHEASTERN MISSISSIPPI,
SOUTHWESTERN ALABAMA, AND PORTIONS OF THE WESTERN FLORIDA PANHANDLE AS
THE OUTER RAINBANDS ON THE EASTERN SIDE OF IDA MOVE ACROSS THE AREA.
THIS TORNADO THREAT IS EXPECTED TO PERSIST AND EXPAND ACROSS MUCH OF
THE AREA TODAY.
3-5 FEET OF COASTAL WATER RISES ABOVE NORMALLY DRY GROUND ALONG THE
BEACHES, SOUNDS, AND THE SHORELINE OF MOBILE BAY WILL CONTINUE TODAY
INTO TONIGHT. 1-3 FEET OF WATER RISE IS POSSIBLE FURTHER EAST INTO THE
WESTERN FLORIDA PANHANDLE. SURF HEIGHTS TODAY WILL REMAIN BETWEEN 9-11
FEET ALONG THE COAST OF ALABAMA AND BETWEEN 7-9 FEET ALONG THE COAST OF
THE WESTERN FLORIDA PANHANDLE. OVERALL, THESE SWELLS ARE LIKELY TO CAUSE
LIFE-THREATENING SURF, WAVE RUN UP, AND DANGEROUS RIP CURRENTS. WAVES
AND SWELLS WILL REMAIN ELEVATED TODAY AND TONIGHT, AND POTENTIALLY INTO
TUESDAY AS STRONG SOUTH TO SOUTHWEST WINDS PERSIST OVER THE MARINE AREAS.
TROPICAL STORM FORCE CONDITIONS, ESPECIALLY IN FREQUENT GUSTS, WILL
CONTINUE TODAY OVER COASTAL ALABAMA, AS WELL AS OVER INTERIOR SOUTHEAST
MISSISSIPPI AND PORTIONS OF SOUTHWEST ALABAMA.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
POTENTIAL IMPACTS FROM THE FLOODING RAIN ARE STILL UNFOLDING ACROSS
PORTIONS OF SOUTHWEST ALABAMA...NORTHWEST FLORIDA...SOUTH CENTRAL
ALABAMA...AND INLAND SOUTHEAST MISSISSIPPI.. REMAIN WELL GUARDED
AGAINST DANGEROUS FLOOD WATERS HAVING POSSIBLE SIGNIFICANT IMPACTS. IF
REALIZED, THESE IMPACTS INCLUDE:
- MODERATE RAINFALL FLOODING MAY PROMPT SEVERAL EVACUATIONS AND
RESCUES.
- RIVERS AND TRIBUTARIES MAY QUICKLY BECOME SWOLLEN WITH SWIFTER
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.
* TORNADOES:
POTENTIAL IMPACTS FROM TORNADOES ARE STILL UNFOLDING ACROSS PORTIONS OF
SOUTHWEST ALABAMA...NORTHWEST FLORIDA...SOUTH CENTRAL ALABAMA...AND
INLAND SOUTHEAST MISSISSIPPI.. REMAIN WELL BRACED AGAINST A TORNADO
EVENT HAVING POSSIBLE LIMITED IMPACTS. IF REALIZED, THESE IMPACTS
INCLUDE:
- THE OCCURRENCE OF ISOLATED TORNADOES CAN HINDER THE EXECUTION
OF EMERGENCY PLANS DURING TROPICAL EVENTS.
- A FEW PLACES MAY EXPERIENCE TORNADO DAMAGE, ALONG WITH POWER
AND COMMUNICATIONS DISRUPTIONS.
- LOCATIONS COULD REALIZE ROOFS PEELED OFF BUILDINGS, CHIMNEYS
TOPPLED, MOBILE HOMES PUSHED OFF FOUNDATIONS OR OVERTURNED,
LARGE TREE TOPS AND BRANCHES SNAPPED OFF, SHALLOW-ROOTED TREES
KNOCKED OVER, MOVING VEHICLES BLOWN OFF ROADS, AND SMALL BOATS
PULLED FROM MOORINGS.
* SURGE:
POTENTIAL IMPACTS FROM THE MAIN SURGE EVENT ARE NOW UNFOLDING ACROSS
COASTAL ALABAMA AND ADJOINING MOBILE BAY SHORELINE. REMAIN WELL AWAY
FROM LIFE-THREATENING SURGE HAVING POSSIBLE SIGNIFICANT IMPACTS. IF
REALIZED, THESE IMPACTS INCLUDE:
- AREAS OF INUNDATION WITH STORM SURGE FLOODING ACCENTUATED BY
WAVES. DAMAGE TO SEVERAL BUILDINGS, MAINLY NEAR THE COAST.
- SECTIONS OF NEAR-SHORE ESCAPE ROUTES AND SECONDARY ROADS BECOME
WEAKENED OR WASHED OUT, ESPECIALLY IN USUALLY VULNERABLE LOW
SPOTS.
- MAJOR BEACH EROSION WITH HEAVY SURF BREACHING DUNES. STRONG AND
NUMEROUS RIP CURRENTS.
- MODERATE DAMAGE TO MARINAS, DOCKS, BOARDWALKS, AND PIERS.
SEVERAL SMALL CRAFT BROKEN AWAY FROM MOORINGS, ESPECIALLY IN
UNPROTECTED ANCHORAGES.
POTENTIAL IMPACTS FROM THE MAIN SURGE EVENT ARE ALSO NOW UNFOLDING
ACROSS COASTAL SECTIONS OF THE WESTERN FLORIDA PANHANDLE. REMAIN WELL
AWAY FROM LOCALLY HAZARDOUS SURGE HAVING POSSIBLE LIMITED IMPACTS.
* WIND:
POTENTIAL IMPACTS FROM THE MAIN WIND EVENT ARE NOW UNFOLDING ACROSS
SOUTHEAST MISSISSIPPI AND FAR SOUTHWEST ALABAMA. REMAIN WELL
SHELTERED FROM HAZARDOUS WIND HAVING POSSIBLE LIMITED IMPACTS. IF
REALIZED, THESE IMPACTS INCLUDE:
- DAMAGE TO PORCHES, AWNINGS, CARPORTS, SHEDS, AND UNANCHORED
MOBILE HOMES. UNSECURED LIGHTWEIGHT OBJECTS BLOWN ABOUT.
- MANY LARGE TREE LIMBS BROKEN OFF. A FEW TREES SNAPPED OR
UPROOTED, BUT WITH GREATER NUMBERS IN PLACES WHERE TREES ARE
SHALLOW ROOTED. SOME FENCES AND ROADWAY SIGNS BLOWN OVER.
- A FEW ROADS IMPASSABLE FROM DEBRIS, PARTICULARLY WITHIN URBAN
OR HEAVILY WOODED PLACES. HAZARDOUS DRIVING CONDITIONS ON
BRIDGES AND OTHER ELEVATED ROADWAYS.
- SCATTERED POWER AND COMMUNICATIONS OUTAGES.
ELSEWHERE ACROSS PORTIONS OF INTERIOR SOUTHWEST AND SOUTH-CENTRAL
ALABAMA AND THE WESTERN FLORIDA PANHANDLE, LITTLE TO NO IMPACT IS
ANTICIPATED.
