COUNTY DEATHS INJURIES EVACUATIONS
DESCRIPTION
---------------------------------------------------------------------
MOBILE 0 3 0
THE WEST END OF DAUPHIN ISLAND WAS SIGNIFICANTLY IMPACTED BY IDA
FROM A COMBINATION OF HIGH SURF, STORM SURGE, AND TROPICAL STORM
FORCE WINDS. THREE MILES OF BIENVILLE BOULEVARD WAS IMPASSABLE DUE
TO SURGE FLOODING AND SAND UP TO FOUR FEET DEEP. THE HIGH SURF ALSO
PRODUCED MINOR DAMAGE TO A FEW HOMES ON THE WEST END. POWER POLES
WERE ALSO KNOCKED DOWN ON THE ISLAND. STORM SURGE INUNDATION PEAKED
BETWEEN 3 AND 5 FEET MHHW ACROSS SOUTHERN MOBILE COUNTY UP INTO THE
FAR NORTH END OF MOBILE BAY. THE HIGHEST TIDAL GAUGE READINGS WERE
3.78 FT MHHW AT COAST GUARD SECTOR MOBILE AND 3.82 FT AT THE BAYOU
LA BATRE BRIDGE. STORM SURGE SURVEYS ALONG SHELL BELT ROAD IN BAYOU
LA BATRE INDICATED WATER LINES THAT REACHED BETWEEN 4-4.5 FT MHHW.
THIS SURGE FLOODING RESULTED IN CLOSURES OF LOW LYING COASTAL ROADS,
SUCH AS SHELL BELT ROAD, THE US HIGHWAY 90 CAUSEWAY, THE FOOT OF THE
DOG RIVER BRIDGE, AND THE DAUPHIN ISLAND CAUSEWAY. COASTAL FLOODING
PERSISTED ACROSS THREE HIGH TIDE CYCLES WHICH RESULTED IN PROLONGED
CLOSURES. OBSERVATIONS AT DAUPHIN ISLAND AND BUCCANEER YACHT CLUB ON
MOBILE BAY MEASURED BRIEF SUSTAINED PERIODS OF TROPICAL STORM FORCE
WINDS BETWEEN 40-45 MPH. GUSTS OF 50 TO 60 MPH WERE RECORDED IN
HEAVIER RAIN BANDS ACROSS CENTRAL AND SOUTHERN MOBILE COUNTY. AN
EF-1 TORNADO IMPACTED PARTS OF SARALAND, SATSUMA, AND CREOLA EARLY
IN THE AFTERNOON ON AUGUST 30TH, RESULTING IN THREE INJURIES. RAINFALL
TOTALS OF 8 TO 11 INCHES WERE RECORDED ACROSS THE COUNTY, ESPECIALLY
IN SOUTHERN AND CENTRAL PORTIONS. THIS HEAVY RAINFALL LED TO SOME
URBAN FLOODING IN NEIGHBORS AND DAMAGED SOME DRAINAGE CULVERTS.

MEASURED ACROSS BALDWIN COUNTY. A PORTION OF RIVER ROAD ALONG STYX
RIVER WAS WASHED OUT DUE TO HEAVY RAINFALL AND FLOODING. A FEW
DRAINAGE CULVERTS WERE ALSO SIGNIFICANT DAMAGED IN THE COUNTY.
TROPICAL STORM CONDITIONS WERE CONFINED PRIMARILY TO IMMEDIATE
COASTAL AREAS, PARTICULARLY ALONG THE FORT MORGAN PENINSULA.
