SITUATION OVERVIEW
------------------
HURRICANE IDALIA CONTINUES TO TRACK NORTHWARD ACROSS THE EASTERN
GULF OF MEXICO WHILE STRENGTHENING. IDALIA IS STILL FORECAST TO MAKE
LANDFALL AS A MAJOR HURRICANE IN THE BIG BEND REGION OF FLORIDA
WEDNESDAY MORNING. AFTER MAKING LANDFALL, IDALIA IS FORECAST TO TRACK
JUST INLAND THROUGH SOUTHEAST GEORGIA AND SOUTHEAST SOUTH CAROLINA
WEDNESDAY EVENING THROUGH EARLY THURSDAY MORNING.
LOCAL IMPACTS FROM IDALIA WILL BEGIN AS EARLY AS WEDNESDAY MORNING AS
HEAVY RAINFALL BEGINS TO OVERSPREAD SOUTHEAST GEORGIA AND SOUTHEAST
SOUTH CAROLINA FROM SOUTHWEST TO NORTHEAST. HEAVY RAINFALL IS EXPECTED
TO CONTINUE THROUGH WEDNESDAY NIGHT ACROSS THE REGION WITH 1 TO
3 INCHES OF RAIN FORECAST ALONG THE COAST AND 4 TO 8 INCHES FORECAST
FOR INLAND LOCATIONS. TROPICAL STORM FORCE WINDS ARE EXPECTED TO
DEVELOP ACROSS SOUTHEAST GEORGIA LATE WEDNESDAY MORNING, ESPECIALLY
ALONG THE COAST, WITH CONDITIONS DETERIORATING WEDNESDAY AFTERNOON AND
INTO WEDNESDAY NIGHT AS TROPICAL STORM FORCE WINDS SPREAD UP THE COAST
AND INTO PORTIONS OF SOUTHEAST SOUTH CAROLINA. TORNADOES WILL BE
POSSIBLE ACROSS THE AREA WEDNESDAY AFTERNOON AND WEDNESDAY NIGHT,
PARTICULARLY ALONG THE COAST, AND WATERSPOUTS WILL BE POSSIBLE ACROSS
THE ADJACENT ATLANTIC COASTAL WATERS. FINALLY, THERE IS THE POTENTIAL
FOR STORM SURGE WEDNESDAY EVENING THROUGH EARLY THURSDAY MORNING ALONG
THE SOUTHEAST GEORGIA AND SOUTHEAST SOUTH CAROLINA COASTS, WHERE
INUNDATION UP TO 4 FEET ABOVE GROUND LEVEL IS POSSIBLE.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
PROTECT AGAINST LIFE-THREATENING RAINFALL FLOODING HAVING POSSIBLE
EXTENSIVE IMPACTS ACROSS SOUTHEAST GEORGIA AND SOUTHEAST SOUTH CAROLINA,
ESPECIALLY INLAND OF THE COAST. POTENTIAL IMPACTS INCLUDE:
- MAJOR RAINFALL FLOODING COULD PROMPT MANY RESCUES.
- RIVERS AND TRIBUTARIES COULD RAPIDLY OVERFLOW THEIR BANKS IN
MULTIPLE LOCATIONS. SMALL STREAMS, CREEKS, CANALS, DITCHES MAY
BECOME DANGEROUS RIVERS. FLOOD CONTROL SYSTEMS AND BARRIERS
COULD BECOME STRESSED.
- FLOOD WATERS COULD ENTER MANY STRUCTURES WITHIN MULTIPLE
COMMUNITIES; SOME STRUCTURES BECOME UNINHABITABLE OR ARE WASHED
AWAY. FLOOD WATERS COULD COVER MULTIPLE 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.
- DRINKING WATER AND SEWER SERVICES COULD BE NEGATIVELY IMPACTED.
- HAZARDOUS CONTAINERS AND MATERIALS COULD POSSIBLY BE PRESENT IN
FLOOD WATERS.
* SURGE:
PROTECT AGAINST LIFE-THREATENING SURGE HAVING POSSIBLE SIGNIFICANT
IMPACTS ACROSS COASTAL AREAS OF SOUTHEAST GEORGIA AND SOUTHEAST SOUTH
CAROLINA. POTENTIAL IMPACTS IN THIS AREA INCLUDE:
- AREAS OF INUNDATION OF SALTWATER ALONG IMMEDIATE SHORELINES AND
IN LOW-LYING SPOTS FARTHER INLAND NEAR RIVERS AND CREEKS, 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 NORMALLY VULNERABLE LOW
SPOTS.
- MODERATE TO MAJOR BEACH EROSION WITH HEAVY SURF BREACHING
DUNES. STRONG AND NUMEROUS RIP CURRENTS.
- MINOR TO MODERATE DAMAGE TO MARINAS, DOCKS, BOARDWALKS, AND
PIERS. SEVERAL SMALL CRAFT BROKEN AWAY FROM MOORINGS,
ESPECIALLY IN UNPROTECTED ANCHORAGES. SOME NAVIGATION AIDS
POSSIBLY DISPLACED WELL OFF STATION, CREATING DIFFICULT
NAVIGATION NEAR INLETS AND WATERWAYS.

HOMES DAMAGED, ESPECIALLY IF UNANCHORED. UNSECURED LIGHTWEIGHT
OBJECTS BECOME DANGEROUS PROJECTILES.
