SITUATION OVERVIEW
------------------
AT 4 PM CDT, HURRICANE IDA WAS APPROACHING THE VERY WARM CENTRAL GULF
OF MEXICO WATERS, MOVING NORTHWEST AT 16 MPH. THIS GENERAL MOTION
SHOULD CONTINUE UNTIL IDA REACHES THE NORTHERN GULF COAST ON SUNDAY. ON
THE FORECAST TRACK, THE CENTER OF IDA WILL MOVE OVER THE CENTRAL GULF
OF MEXICO THIS EVENING AND CONTINUE TO PROGRESS NORTHWEST, MAKING
LANDFALL ALONG THE NORTHERN GULF COAST SUNDAY EVENING.
RAPID STRENGTHENING IS FORECAST TODAY. IDA IS EXPECTED TO BE AN
EXTREMELY DANGEROUS MAJOR HURRICANE WHEN IT APPROACHES THE NORTHERN
GULF COAST SUNDAY. CURRENTLY, HURRICANE-FORCE WINDS EXTEND OUTWARD UP
TO 30 MILES FROM THE CENTER AND TROPICAL-STORM-FORCE WINDS EXTEND
OUTWARD UP TO 125 MILES. IDA IS FORECAST TO INCREASE IN SIZE AS IT
APPROACHES THE COAST WITH THE AREA OF TROPICAL STORM FORCE WINDS LIKELY
EXPANDING FURTHER OUT TO THE EAST FROM THE CENTER BEFORE LANDFALL.
IDA WILL LIKELY BRING RAINFALL AMOUNTS OF 5 TO 10 INCHES, WITH
ISOLATED HIGHER AMOUNTS OF 12 OR MORE INCHES, ESPECIALLY OVER SOUTHEAST
MISSISSIPPI AND COASTAL ALABAMA, SUNDAY INTO MONDAY AND POTENTIALLY
EXTENDING INTO TUESDAY. THIS IS LIKELY TO RESULT IN FLASH, URBAN, SMALL
STREAM, AND RIVER FLOODING OVER PORTIONS OF OUR AREA.
DEPENDING ON THE EXACT TRACK OF IDA AFTER LANDFALL, TROPICAL STORM
FORCE CONDITIONS, ESPECIALLY IN FREQUENT GUSTS, COULD OCCUR OVER
INTERIOR SOUTHEAST MISSISSIPPI AND PORTIONS OF SOUTHWEST AND COASTAL
ALABAMA.
SWELLS WILL BEGIN REACHING OUR PORTION OF THE GULF COAST COAST THIS
EVENING. 2 TO 4 FEET OF COASTAL WATER RISES ABOVE NORMALLY DRY GROUND
ARE EXPECTED ALONG THE BEACHES, SOUNDS, AND THE SHORELINE OF MOBILE
BAY. 1 TO 3 FEET OF WATER RISE IS POSSIBLE FURTHER EAST INTO THE
WESTERN FLORIDA PANHANDLE. SURF HEIGHTS ARE EXPECTED TO INCREASE TO BE
BETWEEN 8-12 FEET TONIGHT INTO SUNDAY. THESE SWELLS ARE LIKELY TO CAUSE
LIFE-THREATENING SURF, WAVE RUN UP, AND DANGEROUS RIP CURRENTS. WAVES
AND SWELLS ARE LIKELY TO REMAIN ELEVATED INTO MONDAY AND POTENTIALLY
TUESDAY AS STRONG SOUTH TO SOUTHWEST WINDS PERSIST OVER THE MARINE
AREAS.
THE TORNADO THREAT WILL ALSO BEGIN TO INCREASE FROM LATE TONIGHT INTO
SUNDAY ACROSS SOUTHEASTERN MISSISSIPPI, SOUTHWESTERN ALABAMA, AND
PORTIONS OF THE WESTERN FLORIDA PANHANDLE AS THE OUTER RAINBANDS ON THE
EAST AND NORTHEAST SIDE OF IDA MOVE INTO AND ACROSS THE AREA. THIS
TORNADO THREAT WILL LIKELY PERSIST AND EXPAND ACROSS MUCH OF THE REGION
SUNDAY NIGHT AND INTO MONDAY.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
PROTECT AGAINST LIFE-THREATENING RAINFALL FLOODING HAVING POSSIBLE
EXTENSIVE IMPACTS ACROSS SOUTHEAST MISSISSIPPI AND PORTIONS OF
SOUTHWEST ALABAMA. 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.
PROTECT AGAINST DANGEROUS RAINFALL FLOODING HAVING POSSIBLE LIMITED
TO SIGNIFICANT IMPACTS ACROSS THE REMAINING PORTIONS OF THE LOCAL AREA.
* WIND:
PROTECT AGAINST HAZARDOUS WIND HAVING POSSIBLE LIMITED IMPACTS ACROSS
SOUTHEAST MISSISSIPPI AND FAR SOUTHWEST ALABAMA. POTENTIAL IMPACTS IN
THIS AREA 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, LITTLE TO NO IMPACT IS ANTICIPATED.
* SURGE:
PREPARE FOR LIFE-THREATENING SURGE HAVING POSSIBLE SIGNIFICANT
IMPACTS ACROSS COASTAL ALABAMA AND ADJOINING MOBILE BAY SHORELINE.
POTENTIAL IMPACTS IN THIS AREA 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.
ALSO, PREPARE FOR LOCALLY HAZARDOUS SURGE HAVING POSSIBLE LIMITED
IMPACTS ACROSS COASTAL SECTIONS OF THE WESTERN FLORIDA PANHANDLE.
* TORNADOES:
PREPARE FOR A TORNADO EVENT HAVING POSSIBLE LIMITED IMPACTS ACROSS
THE ENTIRE LOCAL AREA (SOUTHEAST MISSISSIPPI, SOUTHWEST AND
SOUTH-CENTRAL ALABAMA, AND THE WESTERN FLORIDA PANHANDLE). POTENTIAL
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.
