H. STORM EFFECTS
KATRINA IS ONE OF THE MOST DESTRUCTIVE HURRICANES TO EVER HIT THE UNITED
STATES COAST. SEVERE DAMAGE WAS SEEN NEAR AND UP TO 76 MILES EAST OF
THE CENTER OF KATRINA.  STORM SURGE VALUES APPROACH HURICANE CAMILLES
EXTREME VALUES...WITH HIGH STORM SURGE VALUES OVER A MUCH MORE EXTENSIVE
AREA THAN WITH HURRICANE CAMILLE. ALMOST TOTAL DESTRUCTION WAS OBSERVED
ALONG THE IMMEDIATE COAST IN HANCOCK AND HARRISON WITH STORM SURGE DAMAGE
EXTENDING NORTH ALONG BAYS AND BAYOUS TO  INTERSTATE HIGHWAY 10.

IN SOUTHEAST LOUISIANA...ORLEANS...PLAQUEMINES...ST BERNARD WERE FLOODED
BY STORM SURGE OVERTOPPING AND/OR BREACHING OF LEVEES WITH WIDESPREAD
AND DEEP FLOODING OF HOMES AND BUSINESSES.

ALONG THE NORTH SHORE OF LAKE PONTCHARTRAIN...SEVERE STORM SURGE DAMAGE
WAS EXPERIENCED ALONG THE LAKESHORE FROM MANDEVILLE TO SLIDELL WITH
STORM SURGE WATER MOVING NORTH INTO OLD TOWNE SLIDELL...UP TO 6 FEET DEEP
IN SOME LOCATIONS.

IN AREAS AWAY FROM STORM SURGE FLOODING...WIND DAMAGE WAS REPORTED IN
A WIDE AREA ACROSS SOUTHEAST LOUISIANA AND SOUTH MISSISSIPPI. DAMAGE
FROM FALLEN TREES TOOK A HEAVY TOLL ON HOUSE ROOFS AND POWER LINES.

INSURED PROPERTY LOSSES ESTIMATED AS THE FOLLOWING...
LOUISIANA 22.6 BILLION DOLLARS..MISSISSIPPI 9.8 BILLION DOLLARS. DOLLAR
ESTIMATES DO NOT INCLUDE LOSSES COVERED BY THE FEDERAL FLOOD INSURANCE
PROGRAM. SOURCE...ISO PROPERTY CLAIMS SERVICE PRESS RELEASE.

ON OCTOBER 20...THE DEATH TOLL STOOD AT 1053 IN LOUISIANA AND 228 IN
MISSISSIPPI. THE FIGURES LIKELY INCLUDES DIRECT AND INDIRECT
FATALITIES.
