7 TO 9 FEET IN ESCAMBIA COUNTY
5 TO 8 FEET IN SANTA ROSA COUNTY
4 TO 6 FEET IN OKALOOSA COUNTY

E. BEACH EROSION...

MAJOR BEACH EROSION OCCURRED FROM DAUPHIN ISLAND TO EAST OF
DESTIN.

F. FLOODING...

STORM TIDE FLOODING OCCURRED ON DAUPHIN ISLAND WITH THE WEST END
OF THE ISLAND COMPLETELY SUBMERGED. BETWEEN FORT MORGAN AND
PERDIDO KEY A FEW BREACHES OCCURRED. BREACHES ALSO OCCURRED ON
SANTA ROSA ISLAND IN NORTHWEST FLORIDA. BAYOU LA BATRE HAD MAJOR
FLOODING FROM THE STORM TIDE. THE CAUSEWAY AND DOWNTOWN MOBILE
SAW NEAR RECORD STORM TIDES (ONLY POSSIBLY EXCEEDED BY THE 1916
HURRICANE). THIS RECORD SURGE WAS PREDICTED BY THE MOBILE
NATIONAL WEATHER SERVICE OFFICE TWO DAYS BEFORE KATRINA MOVED
ASHORE. FLASH FLOODING OCCURRED IN SOUTHWEST ALABAMA AND
SOUTHEAST MISSISSIPPI BUT ONLY LASTED FOR A COUPLE OF HOURS DUE
TO THE FAST MOVEMENT OF KATRINA.

G. TORNADOES...

SEVERAL WEAK TORNADOES MAY HAVE OCCURRED ACROSS SOUTHEAST
MISSISSIPPI...SOUTHWEST ALABAMA AND NORTHWEST FLORIDA IN THE
BANDS THAT PRECEDED KATRINA.

H. STORM EFFECTS...

HIGH WINDS FROM KATRINA CAUSED SIGNIFICANT TREE AND POWER LINE
DAMAGE TO THE COUNTIES THAT BORDER THE MISSISSIPPI AND ALABAMA
STATE LINE WITH STONE AND PERRY COUNTIES IN SOUTHEAST MISSISSIPPI
RECEIVING THE MOST DAMAGE FROM THE WINDS. THE WINDS WERE HIGHER
AS YOU WENT WEST TOWARD THE CENTER OF KATRINA. THE MAJOR PROBLEM
ALONG THE COASTAL AREAS WAS THE RECORD STORM TIDES IN MOBILE
COUNTY WITH BALDWIN...ESCAMBIA...SANTA ROSA AND OKALOOSA
COUNTIES RECEIVING SIGNIFICANT COASTAL FLOODING FROM THE STORM
TIDES. THE STORM TIDES WERE LESS AS YOU WENT EAST TOWARD
DESTIN. HIGHWAY 98 IN OKALOOSA COUNTY WAS AGAIN CUT OFF BY THE
SURGE...AS HAS BEEN THE CASE FOR THE PAST SEVERAL STORMS THAT
HAVE THREATENED THAT AREA. GOING WEST TO EAST WALLACE TUNNEL ON
I-10 IN MOBILE WAS CLOSED DUE TO THE HIGH SURGE. I-10 ACROSS
PENSACOLA BAY WAS ALSO CLOSED BECAUSE OF THE HIGH WINDS AND THE
STORM SURGE. AN OIL RIG BROKE LOOSE AND FLOATED NORTH UP MOBILE
BAY AND STRUCK THE COCHRAN-AFRICATOWN BRIDGE ACROSS MOBILE BAY.
THE BRIDGE HAD TO BE CLOSED FOR A WHILE UNTIL THE RIG COULD BE
PULLED AWAY FROM THE BRIDGE AND THE BRIDGE INSPECTED. SO FAR NO
DIRECT DEATHS FROM KATRINA HAVE BEEN REPORTED ACROSS SOUTHEAST
MISSISSIPPI...SOUTHWEST ALABAMA OR NORTHWEST FLORIDA.
PRELIMINARY DAMAGE ESTIMATES FROM KATRINA COULD APPROACH MORE
THAN A BILLION DOLLARS.

...THIS SUMMARY WILL BE UPDATED AS LATER DATA BECOMES AVAILABLE...
