LOWER MOBILE-LOWER BALDWIN-COASTAL ESCAMBIA-COASTAL SANTA ROSA-
COASTAL OKALOOSA-
935 AM CST TUE NOV 10 2009

THE REMNANTS OF IDA ARE MOVING NORTH AND EAST OF THE AREA BRINGING
GALE FORCE WIND FROM THE NORTH OVER AREA BAYS AND WATERWAYS. SOME TIDE
STATIONS REPORT THAT TIDES 2 TO 3 FEET ABOVE NORMAL ARE STILL
OCCURRING ALTHOUGH THEY ARE DECREASING RAPIDLY. THE PRESENCE OF HIGH
TIDES WILL AFFECT PORT OPERATIONS AND VESSEL HANDLING THROUGH THIS
AFTERNOON WHICH INCLUDES THE COASTAL WATERS OUT TO 60 NM OFF ALABAMA
AND NORTHWEST FLORIDA...AS WELL AS MOBILE BAY. LATER THIS MORNING AND
THIS AFTERNOON THE TIDE LEVEL MAY FALL SIGNIFICANTLY BELOW NORMAL DUE
TO THE EFFECT OF STRONG NORTH WINDS PUSHING WATER OUT OF THE BAYS.
SUCH CONDITIONS COULD RISK VESSELS BECOMING AGROUND...BLOCKING VITAL
INTAKES AND FITTINGS. MARINERS...ESPECIALLY LARGE VESSEL OPERATORS AT
ANCHOR...MOORED...OR OPERATING IN WATER DEPTH NEAR VESSEL DRAFT
SHOULD WATCH FOR UNUSUALLY LOW TIDES THROUGH THIS EVENING.

.SHORT TERM...(TODAY THROUGH TONIGHT)LATEST NATIONAL HURRICANE FORECAST
HAS CENTER OF TROPICAL STORM IDA TRACKING NORTH-NORTHEASTWARD ALONG
THE WEST BANK OF MOBILE BAY THIS MORNING. IDA WILL INTERACT WITH A
STRONG UPPER TROUGH MOVING EAST OVER THE FORECAST AREA...CAUSING IDA
TO TURN MORE TOWARD THE EAST THIS AFTERNOON...EVENTUALLY TRACKING
ABOUT 10 TO 20 MILES NORTH OF THE I-10 CORRIDOR. IDA WILL CONTINUE
TO WEAKEN THROUGHOUT THE DAY AS IT MAKES ITS TRANSFORMATION TO AN
EXTRA-TROPICAL SYSTEM.

TIDE GAGES HAVE CONTINUED TO SHOW A RAPID RATE OF INCREASE IN HIGH
WATER LEVELS...WITH TOTAL STORM HEIGHTS CURRENTLY AT ABOUT THREE TO
FOUR FEET. STRONG NORTHWEST WINDS DEVELOPING THIS AFTERNOON WILL

IN EFFECT THROUGH AT LEAST THE MORNING HOURS.

RAIN...HEAVY AT TIMES...WILL OCCUR PRIMARILY ACROSS THE NORTHEAST

HALF OF THE SHORT TERM...A SPREAD IS IN EVIDENCE BETWEEN THE
RESULTANT MOS. HAVE STARTED WITH THE GFS/MAV SOLUTION...BUT BUMPED UP
TEMPS A BIT FOR THE WEDNESDAY THROUGH THURSDAY TIME FRAME AS FEEL
THAT THERE WILL BE MORE WARMING THAN THE MAV/GFS SOLUTIONS IS ADVERTISING

WINTER MODE.

.LONG TERM...(THURSDAY NIGHT ON)THURSDAY NIGHT INTO THE WEEKEND...MODELS
ARE IN PRETTY GOOD AGREEMENT...WITH A SHORTWAVE DIVING SOUTH OVER THE
EASTERN CONUS AND COMBINING WITH THE REMAINS OF IDA... THEN

TIME PERIOD...A STACKED SET OF SHORTWAVES MOVES EAST OVER THE WESTERN
CONUS...MOVING OVER THE ROCKIES FRIDAY INTO FRIDAY NIGHT. ANOTHER
STRONG SHORTWAVE IS HOT ON THE HEELS OF THE FIRST SERIES OF
SHORTWAVES. FROM SATURDAY NIGHT ON...GUIDANCE IS ADVERTISING THIS
FOLLOWING SHORTWAVE ABSORBING THE LEADING ENERGY...BUT GUIDANCE IS
BEGINNING TO DISAGREE. SEEMS AS THOUGH THE ECMWF AND GFS HAVE
SWAPPED SOLUTIONS...WITH THE ECMWF PUSHING THE COMBINED ROCKIES UPPER
SHORTWAVE QUICKLY SOUTHEAST...PUSHING A FRONT ACROSS THE AREA MONDAY.
THE GFS IS NOW ADVERTISING A SLOW EASTWARD WANDERING...WITH A WEAKER
FRONT PUSHING ACROSS THE FA TUESDAY...THEN CONTINUING TO MEANDER EAST.
HAVE LESS THAN AVERAGE CONFIDENCE IN THE FORECAST.
