BEACH EROSION MAJOR F. FLOODING OR FLASH FLOODING MAJOR STORM TIDE FLOODING FROM NEW ORLEANS TO EAST OF PASCAGOULA. WATER WAS UP TO THE ROOFS OF NUMEROUS HOMES...WITH MANY HAVING THE FLOOD WATERS COVERING THEM. THE NEW ORLEANS AREA HAD MAJOR FLOODING A COUPLE OF DAYS AFTER KATRINA MOVED INLAND WHEN THE LEVEE SYSTEM BREACHED IN SEVERAL LOCATIONS PUTTING WATER ACROSS ORLEANS AND PLAQUEMINES PARISHES. G. TORNADOES UNKNOWN H. STORM EFFECTS KATRINA HAS TO BE ONE OF THE STRONGEST HURRICANES TO EVER HIT THIS AREA. TOTAL DESTRUCTION WAS SEEN ALONG AND UP TO 60 MILES EAST OF THE CENTER OF KATRINA. STORM SURGE VALUES WERE PROBABLY HIGHER IN KATRINA ALONG THE MISSISSIPPI COAST THAN THEY WERE DURING CAMILLE. ALMOST TOTAL DESTRUCTION WAS OBSERVED IN HANCOCK AND HARRISON COUNTIES IN MISSISSIPPI ALONG THE IMMEDIATE COAST AND EXTENDED INLAND TO NEAR I-10. MOST BUILDINGS WERE TOTALLY DESTROYED. MANY PEOPLE WHO REFUSED TO EVACUATE WERE TRAPPED IN THEIR HOMES AND HAD TO SEEK SHELTER IN THEIR ATTICS AND THEN SOMEHOW GET ON THEIR ROOFS TO AVOID BEING TRAPPED. MANY DID NOT MAKE IT. DUE TO MULTIPLE FAILURES OF THE LEVEE SYSTEM AROUND LAKE PONTCHARTRAIN...NEW ORLEANS HAD HIGHER WATER VALUES AFTER KATRINA HAD MOVED INLAND. SOME PLACES IN NEW ORLEANS HAD WATER DEPTHS UP TO 20 FEET...DAYS AFTER THE STORM. AS OF FRIDAY...WATER STILL COVERED MANY PARTS OF NEW ORLEANS. PEOPLE WHO ESCAPED THE SURGE ENDED UP STRANDED AS THE WATER ROSE. MANY HAD TO TAKE REFUGE ON ROOFS OR INTERSTATES. THE SUPERDOME...WHICH WAS HOUSING EVACUEES...HAD ROOF DAMAGE AND ENDED UP BEING EVACUATED AFTER THE STORM DUE TO THE RISING WATERS FROM THE BREECHES IN THE LEVEE. IT IS ESTIMATED THAT 185 PEOPLE HAVE DIED FROM THE STORM IN MISSISSIPPI AND MAYBE THOUSANDS DEAD IN SOUTHEAST LOUISIANA. THIS WILL LIKELY END UP BEING THE COSTLIEST NATURAL DISASTER TO STRIKE THE UNITED STATES. BEELER/CULLEN $$
