AREA FORECAST DISCUSSION...CORR TO LAKE WIND ADVISORY
NATIONAL WEATHER SERVICE JACKSONVILLE FL
309 PM EDT SAT JUL 9 2005
...LAKE WIND ADVISORY TONIGHT FOR SUWANNEE...GILCHRIST...
ALACHUA AND MARION COUNTIES...
...HURRICANE DENNIS OUTER RAIN BANDS TO CONTINUE OVER THE AREA...
...WIDESPREAD HEAVY RAINFALL LIKELY THROUGH MONDAY...
.SHORT TERM...HURRICANE DENNIS CONTINUES TO MOVE NORTHWEST WITH
OUTERMOST RAINBAND OVER THE GEORGIA PORTION...THE SECOND RAINBAND
MOVING THROUGH THE SUWANNEE VALLEY...AND AN APPROACHING BAND OVER THE
TAMPA AREA. THESE BANDS HAVE BEEN PROGRESSIVELY GETTING STRONGER WITH
DAYTIME HEATING...EXHIBITING QUITE A BIT OF LIGHTNING FOR A LARGELY
TROPICAL ENVIRONMENT. HAVE SEEN AN INCREASING WIND PROFILE IN THE
LOWEST LAYERS WITH EVEN SOME OF THE STRONGER SHOWERS PRODUCING 30
KNOT WIND GUSTS. EXPECT SHEAR PROFILE TO FURTHER INCREASE THROUGH
THIS EVENING WITH THE LIKELIHOOD OF ISOLATED TORNADOES INCREASING.
MAIN FORECAST CHALLENGE TONIGHT WILL BE TIMING RAINBANDS WHICH ARE
SEPARATED BY QUITE A DISTANCE. GUIDANCE POPS SHOWS ONLY SCATTERED
POPS ALONG THE COAST OVERNIGHT...BUT WITH DECENT MOISTURE FLUX
CONVERGENCE ALONG WITH DEWPOINTS IN THE UPPER 70S TO AROUND 80...SEE
NO REASON WHY POPS WILL NOT INCREASE THROUGH DAYBREAK SUNDAY.
THEREAFTER...WE WILL BE DEALING WITH THE MORE SOLID RAINBAND
FEATURES FROM DENNIS WITH HEAVIEST RAINFALL AMOUNTS EXPECTED OVER
THE INTERIOR ZONES. MODEL CLUSTERS ARE IN GOOD AGREEMENT THUS FAR...
BUT MINOR DEVIATIONS FROM CURRENT FORECAST TRACK AND INTENSITY
WILL PRODUCE SIGNIFICANT CHANGES TO POP DISTRIBUTION. FOR NOW...WILL
GO WITH CATEGORICAL POPS BASED ON LATEST TRACK FOR ALL AREAS AND
KEEP FLOOD WATCH GOING AS IS.
CONCERNS REGARDING FLOODING WILL CONTINUE INTO EARLY NEXT WEEK AS
IT REMAINS A GOOD POSSIBILITY THAT MAIN RAIN BAND AXIS WILL SET UP
OVER THE FLORIDA PENINSULA. NAM HAS THIS AXIS JUST WEST
OF THE AREA WHILE THE MORE RELIABLE GFS HAS IT STRAIGHT DOWN THE
SPINE OF THE PENINSULA. ACTIVITY BY THIS TIME MAY GET TO BE MORE
DIURNAL IN NATURE...BUT PERSISTENT CONVERGENT ZONE WITH AMPLE
MOISTURE LOOKS TO INCREASE FLOOD POTENTIAL.
.LONG TERM...REMNANT LOW PRESSURE SYSTEM MOVES INTO THE OHIO VALLEY
BY WEDNESDAY WITH SURFACE RIDGE AXIS RE-ESTABLISHING ITSELF OVER
THE AREA. THIS WILL LEAD TO MORE TYPICAL DIURNAL TYPE CONVECTION FOR
THE REMAINDER OF THE WORK WEEK.
&&
.MARINE...LOCAL MARINE OBS INDICATE WINDS/ATTENDANT SEAS SLOWLY
INCREASING...WITH EASTERLY WINDS AROUND 15 KNOTS AND SEAS 3 TO 5
FEET. CONDITIONS TO SLOWLY DETERIORATE REMAINDER OF TODAY THROUGH
SUNDAY AS HURRICANE DENNIS INTENSIFIES WHILE TRACKING NORTH OVER THE
EASTERN GULF OF MEXICO. SCA CONDITIONS EXPECTED TO DEVELOP IN FLORIDA
LEGS THIS AFTERNOON...SLOWLY SPREADING NORTH IN GEORGIA LEGS TONIGHT.
CONDITIONS TO IMPROVE...ALBEIT SLOWLY...SUNDAY NIGHT AS DENNIS
ADVANCES INLAND.

LOCALLY HEAVY RAINFALL IS LIKELY OVER THE AREA LATE THIS AFTERNOON THROUGH SUNDAY NIGHT. WIDESPREAD RAINFALL AMOUNTS OF 2 TO 4 INCHES CAN BE EXPECTED...WITH THE HIGHEST AMOUNTS TOWARD THE INTERSTATE 75 CORRIDOR.

PLEASE REFER TO THE LATEST SURF ZONE FORECAST FOR DETAILS. MINOR RIVER FLOODING WILL CONTINUE ON THE SATILLA AND SANTA FE RIVERS. PLEASE REFER TO THE LATEST RIVER FLOOD STATEMENTS FOR MORE DETAILS. .DAYS TWO THROUGH SEVEN...SUNDAY THROUGH SATURDAY... THE RISK OF RIP CURRENTS WILL BE HIGH ON SUNDAY DUE TO STRONG ONSHORE FLOW AND HIGH BREAKERS. WIDESPREAD RAIN AND NUMEROUS THUNDERSTORMS WILL CONTINUE SUNDAY AND INTO MONDAY AS HURRICANE DENNIS MOVES INLAND. LOCALLY HEAVY RAINFALL AND FLOODING IN LOW LYING AREAS WILL STILL BE POSSIBLE. .SPOTTER INFORMATION STATEMENT...
