.......................PREVIOUS DISCUSSION..........................

.SHORT TERM TODAY AND TONIGHT...APOLOGIZE FOR THE DELAY IN ALL OF
THE PUBLIC PRODUCTS...BUT WANTED TO GET ALL THE LATEST ON GUSTAV
BEFORE TRANSMITTING. HURRICANE GUSTAV WILL BE MAKING LANDFALL BY
MIDDAY OVER THE SOUTHEAST COAST OF LOUISIANA COAST...NOT FAR WEST OF
GRAND ISLE. WELL EAST OF THE CENTER...WILL SEE RAINBANDS AND SQUALLY
WEATHER ROTATING IN OFF THE GULF. WE FORECAST THE HIGHEST
PRECIPITATION CHANCES OVER THE SOUTHWEST HALF OF THE AREA TODAY AND
TONIGHT. SOME OF THE RAIN BANDS WILL CONTAIN HEAVY RAINS WITH
OCCASIONAL TROPICAL STORM FORCE WIND GUSTS. EXCESSIVE RAINS COULD
FORM WHERE RAIN BAND DETACHMENT SETS UP AND PERSISTS FOR SEVERAL
HOURS OVER THE SAME AREAS. WILL HAVE A FLASH FLOOD WATCH OUT FOR
THOSE ZONES WHERE WE EXPECT THIS POTENTIAL. GRIDDED WEATHER WILL ALSO
CONTAIN THE POTENTIAL OF TORNADOES OVER THE COASTAL COUNTIES AND
SOUTHEAST MISSISSIPPI AS THESE AREAS LOOK TO HAVE THE HIGHEST
PROBABILITY OF IMPACTS FROM THESE AND CLOSEST TO THE FAVORED
EAST/NORTHEAST SIDE OF GUSTAVS CIRCULATION. TIDAL FLOODING
...DANGEROUS RIP CURRENTS AND INSTANCES OF BEACH EROSION WILL ALSO
PRESENT HAZARDS TODAY. FOR MORE SPECIFIC INFORMATION ON WHAT IS
EXPECTED...REFER TO THE LOCAL STATEMENTS ISSUED BY THE NATIONAL
WEATHER SERVICE IN MOBILE ALABAMA. /10

.LONG TERM TUESDAY THROUGH SUNDAY...SOME FORECAST CHALLENGES IN
THE MEDIUM RANGE WEATHER PICTURE. ALTHOUGH GUSTAV WILL BE WEAKENING
OVER WEST CENTRAL LOUISIANA OR EAST TEXAS TUESDAY...WOULD NOT BE
SURPRISED TO SEE A DETACHED RAINBAND THAT BECOMES QUASI-STATIONARY
OVER SOUTHEAST MISSISSIPPI AND SOUTHWEST ALABAMA.
IF THIS SETS UP...EXCESSIVE RAINS WOULD BE LIKELY. HEADING INTO THE
MIDDLE OF THE WEEK...STRENGTHENING MID LEVEL HEIGHTS OVER THE MID
ATLANTIC...COUPLED WITH HANNA NEAR THE BAHAMAS...FAVORS A WESTWARD
EXPANSION OF INCREASED SUBSIDENCE OVER THE SOUTHEAST AND A NET
DECREASE IN PRECIPITATION PROBABILITIES BY THURSDAY. BY FRIDAY...
LEFTOVER MOISTURE BY GUSTAV LOOKS TO BE SHEARED EASTWARD WITH
CHANCES OF SHOWERS AND THUNDERSTORMS COMING BACK UP FRIDAY AND
SATURDAY. WE ANTICIPATE NO PROBLEMS WITH HANNA. SAW NO REASON TO
DEVIATE FROM THE EXTENDED RANGE FORECASTS FOR TEMPERATURES WHICH ARE
NOT THAT FAR FROM SEASONAL NORMALS. /10

&&

.AVIATION...TAF SITES WILL SEE MVFR CONDITIONS PREVAILING
OCCASIONALLY LOWERING TO IFR IN SQUALLS. TROPICAL STORM FORCE WINDS
WILL BE HAZARDOUS FOR ASCENT AND DESCENT.

&&

.MARINE...MAJOR HURRICANE GUSTAV WILL MAKE LANDFALL AROUND MIDDAY
TODAY ON THE SOUTHEAST LOUISIANA COAST. MARINERS ARE URGED TO REMAIN
IN PORT AND CLOSELY MONITOR THE NATIONAL HURRICANE CENTER FORECASTS
AND ADVISORIES CONCERNING THIS DANGEROUS HURRICANE. GUSTAV WEAKENS AS
IT CONTINUES MOVING INLAND ACROSS LOUISIANA AND INTO EASTERN TEXAS
TONIGHT THROUGH FRIDAY. THE STRONG SOUTHEAST WINDS OVER THE MARINE
AREA WILL SUBSIDE BELOW 20 KNOTS ON TUESDAY WITH SEAS SUBSIDING BELOW
7 FEET BY TUESDAY EVENING...WITH WINDS AND SEAS CONTINUING TO SUBSIDE
THROUGH FRIDAY.
