SITUATION OVERVIEW
------------------
AT 4 PM CDT, EXTREMELY DANGEROUS HURRICANE IDA MADE LANDFALL LATE THIS
MORNING OVER SOUTHEAST LOUISIANA NEAR PORT FOURCHON AS A MAJOR
HURRICANE. IDA'S MAXIMUM SUSTAINED WINDS AT LANDFALL WERE ESTIMATED TO
BE 150 MPH WITH A MINIMUM CENTRAL PRESSURE OF 930 MB. HURRICANE- FORCE
WINDS CURRENTLY EXTEND OUTWARD UP TO 45 MILES FROM THE CENTER AND
TROPICAL-STORM-FORCE WINDS EXTEND OUTWARD UP TO 150 MILES. IDA
CONTINUES TO MOVE NORTHWEST AT 10 MPH AND ON THE CURRENT FORECAST
TRACK, THE CENTER OF IDA WILL MOVE FARTHER INLAND OVER SOUTHEAST
LOUISIANA TONIGHT.
IDA IS EXPECTED TO BRING RAINFALL AMOUNTS OF 8-12 INCHES, WITH
ISOLATED HIGHER AMOUNTS UP TO 18 INCHES THROUGH MIDWEEK OVER SOUTHEAST
MISSISSIPPI. OVER COASTAL ALABAMA AND THE WESTERN FLORIDA PANHANDLE,
5-10 INCHES OF RAIN WITH ISOLATED HIGHER AMOUNTS UP TO 15 INCHES ARE
POSSIBLE. MEANWHILE, 3-8 INCHES OF RAIN ARE EXPECTED ELSEWHERE DURING
THIS TIME. 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 NORTHEAST AND EAST SIDE OF IDA MOVE INTO AND
ACROSS THE AREA. THIS TORNADO THREAT IS EXPECTED TO PERSIST AND EXPAND
ACROSS MUCH OF THE REGION TONIGHT INTO MONDAY.
SWELLS CONTINUE TO IMPACT OUR PORTION OF THE GULF COAST. 3-5 FEET OF
COASTAL WATER RISES ABOVE NORMALLY DRY GROUND ARE EXPECTED ALONG THE
BEACHES, SOUNDS, AND THE SHORELINE OF MOBILE BAY. 1-3 FEET OF WATER
RISE IS POSSIBLE FURTHER EAST INTO THE WESTERN FLORIDA PANHANDLE. SURF
HEIGHTS WILL INCREASE TO BE BETWEEN 10-15 FEET THROUGH TONIGHT. ON
MONDAY, SURF HEIGHTS ARE ANTICIPATED TO BE 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 ARE LIKELY TO REMAIN ELEVATED INTO MONDAY AND POTENTIALLY
TUESDAY AS STRONG SOUTH TO SOUTHWEST WINDS PERSIST OVER THE MARINE
AREAS.
TROPICAL STORM FORCE CONDITIONS, ESPECIALLY IN FREQUENT GUSTS, HAVE
OCCURRED OVER PORTIONS OF COASTAL ALABAMA SO FAR TODAY. THESE
CONDITIONS WILL CONTINUE TO BE POSSIBLE OVER THESE AREAS AS WELL AS
OVER INTERIOR SOUTHEAST MISSISSIPPI AND PORTIONS OF SOUTHWEST ALABAMA
AS IDA TURNS NORTHWARD OVERNIGHT AND MOVES FURTHER INLAND OVER PORTIONS
OF WESTERN MISSISSIPPI MONDAY AND MONDAY NIGHT.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
POTENTIAL IMPACTS FROM THE FLOODING RAIN ARE STILL UNFOLDING ACROSS
SOUTHEAST MISSISSIPPI, SOUTHWEST ALABAMA, AND THE WESTERN FLORIDA
PANHANDLE. REMAIN WELL GUARDED AGAINST LIFE-THREATENING FLOOD WATERS
HAVING POSSIBLE EXTENSIVE IMPACTS. IF REALIZED, THESE 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.
POTENTIAL IMPACTS FROM THE FLOODING RAIN ARE STILL UNFOLDING ACROSS
SOUTH-CENTRAL ALABAMA. REMAIN WELL GUARDED AGAINST DANGEROUS FLOOD
WATERS HAVING POSSIBLE LIMITED TO SIGNIFICANT IMPACTS.
* TORNADOES:
POTENTIAL IMPACTS FROM TORNADOES ARE STILL UNFOLDING ACROSS PORTIONS
OF SOUTHEAST MISSISSIPPI, FAR SOUTHWEST ALABAMA, AND THE FAR WESTERN
FLORIDA PANHANDLE. REMAIN WELL BRACED AGAINST A DANGEROUS TORNADO
EVENT HAVING POSSIBLE SIGNIFICANT IMPACTS. IF REALIZED, THESE IMPACTS
INCLUDE:
- THE OCCURRENCE OF SCATTERED TORNADOES CAN HINDER THE EXECUTION
OF EMERGENCY PLANS DURING TROPICAL EVENTS.
- SEVERAL PLACES MAY EXPERIENCE TORNADO DAMAGE WITH A FEW SPOTS
OF CONSIDERABLE DAMAGE, POWER LOSS, AND COMMUNICATIONS FAILURES.
- LOCATIONS COULD REALIZE ROOFS TORN OFF FRAME HOUSES, MOBILE
HOMES DEMOLISHED, BOXCARS OVERTURNED, LARGE TREES SNAPPED OR
UPROOTED, VEHICLES TUMBLED, AND SMALL BOATS TOSSED ABOUT.
DANGEROUS PROJECTILES CAN ADD TO THE TOLL.
POTENTIAL IMPACTS FROM TORNADOES ARE STILL UNFOLDING ACROSS THE
REMAINDER OF THE AREA. REMAIN WELL BRACED AGAINST A TORNADO EVENT
HAVING POSSIBLE LIMITED IMPACTS.
* 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.
