TROPICAL STORM ISAAC DISCUSSION NUMBER 29
NWS NATIONAL HURRICANE CENTER MIAMI FL AL092012
400 AM CDT TUE AUG 28 2012

REPORTS FROM THE AIR FORCE HURRICANE HUNTER AIRCRAFT INDICATE THAT
THE CENTRAL PRESSURE HAS DROPPED A LITTLE MORE...BUT SO FAR...THE
MAXIMUM FLIGHT-LEVEL AND SFMR-OBSERVED SURFACE WINDS STILL DO NOT
QUITE SUPPORT HURRICANE INTENSITY. THE CURRENT INTENSITY IS HELD
AT 60 KT PENDING ADDITIONAL OBSERVATIONS FROM THE HURRICANE
HUNTERS. ALTHOUGH THE WIND FIELD REMAINS RATHER BROAD AND
RELATIVELY FLAT...RECENT AIRCRAFT DATA SUGGEST THAT THE MAXIMUM
WINDS ARE NOW OCCURRING SOMEWHAT CLOSER TO THE CENTER OVER THE
NORTHERN SEMICIRCLE OF THE CYCLONE. THIS WOULD SUGGEST THAT THE
INNER CORE CIRCULATION IS BECOMING BETTER DEFINED...AND
STRENGTHENING MIGHT BE IMMINENT. UPPER-LEVEL OUTFLOW IS
WELL-ESTABLISHED OVER THE SOUTHERN SEMICIRCLE OF THE SYSTEM...BUT
CENTRAL CONVECTION CONTINUES TO FLUCTUATE. THE LATTER IS
PRESUMABLY DUE TO A CONTINUED INTRUSION OF DRY AIR INTO THE CORE
REGION. THE STATISTICAL-DYNAMICAL GUIDANCE IS A LITTLE LOWER THAN
IN PREVIOUS RUNS...AND THE STORM HAS ONLY ABOUT 12-24 HOURS BEFORE
MOVING INLAND. THE OFFICIAL INTENSITY FORECAST IS JUST SLIGHTLY
LOWER THAN THE PREVIOUS ONE.

CENTER FIXES FROM THE AIRCRAFT INDICATE THAT THE STORM HAS WOBBLED
ON A GENERALLY WESTWARD COURSE OVER THE PAST FEW HOURS. THIS IS
BELIEVED TO BE TEMPORARY...HOWEVER...AND THE LONGER-TERM MOTION
ESTIMATE IS ABOUT 305/10. THE CURRENT AND FORECAST STEERING REGIME
ARE BASICALLY THE SAME AS IN THE PREVIOUS PACKAGE. ISAAC IS
EXPECTED TO MOVE INTO A WEAKNESS IN THE SUBTROPICAL RIDGE NEAR THE
NORTH-CENTRAL GULF COAST...WITH SOME SLOWING OF FORWARD SPEED
DURING THE NEXT COUPLE OF DAYS AS A RIDGE BUILDS A LITTLE TO THE
NORTHWEST OF THE CYCLONE. LATER ON...THE SYSTEM SHOULD TURN
NORTHWARD AND NORTHEASTWARD INTO THE OHIO VALLEY REGION AS IT MOVES
AROUND THE WESTERN PERIPHERY OF A MID-LEVEL ANTICYCLONE.

ISAAC IS A LARGE TROPICAL CYCLONE. A DANGEROUS STORM SURGE...HEAVY
RAINFALL...AND STRONG WINDS EXTEND WELL AWAY FROM THE CENTER AND
ARE EXPECTED TO AFFECT A LARGE PORTION OF THE NORTHERN GULF COAST.
FOR THIS REASON...IT IS IMPORTANT NOT TO FOCUS ON THE EXACT CENTER
LOCATION. THE THREAT OF HEAVY RAINFALL AND FLOODING IS ALSO
EXPECTED TO SPREAD INLAND OVER THE LOWER MISSISSIPPI VALLEY REGION
DURING THE NEXT FEW DAYS.

TROPICAL STORM ISAAC DISCUSSION NUMBER 30
NWS NATIONAL HURRICANE CENTER MIAMI FL AL092012
1000 AM CDT TUE AUG 28 2012

REPORTS FROM AIR FORCE AND NOAA HURRICANE HUNTER AIRCRAFT INDICATE
THE CENTRAL PRESSURE HAS DECREASED TO ABOUT 976 MB SINCE THE
PREVIOUS ADVISORY...BUT IT HAS LEVELED OFF OVER THE PAST FEW HOURS.
THE MAXIMUM 850 MB FLIGHT-LEVEL WIND OBSERVED HAS BEEN 89 KT...
WHICH EQUATES TO A SURFACE WIND OF ABOUT 71 KT. HOWEVER...
BIAS-ADJUSTED SFMR SURFACE WINDS HAVE ONLY BEEN AROUND 60-62 KT...
WHICH CORRELATES WELL WITH DROPSONDE BOUNDARY LAYER-DERIVED SURFACE
WINDS. AS SUCH...THE INTENSITY OF ISAAC IS BEING MAINTAINED AT 60
KT...WHICH IS JUST BELOW HURRICANE STATUS.

CENTER FIXES FROM THE AIRCRAFT INDICATE THAT ISAAC HAS BEEN WOBBLING
IN A GENERAL NORTHWESTWARD MOTION OF 310/09 KT. THERE REMAINS NO
SIGNIFICANT CHANGE TO THE PREVIOUS FORECAST TRACK OR REASONING.
ISAAC IS FORECAST TO MOVE INTO A WEAKNESS IN THE SUBTROPICAL RIDGE
NEAR THE NORTH-CENTRAL GULF COAST OVER THE NEXT 24-36 HOURS...
ACCOMPANIED BY A GRADUAL DECREASE IN THE FORWARD SPEED. AS THE
RIDGE BUILDS BACK IN TO THE NORTH OF THE CYCLONE...ISAAC IS
EXPECTED TO TURN A LITTLE MORE TOWARD THE WEST-NORTHWEST BEFORE IT
TURNS NORTHWARD ON DAY 4...AND MOVES NORTHEASTWARD INTO THE OHIO
VALLEY REGION ON DAY 5. THE OFFICIAL FORECAST TRACK HAS BEEN NUDGED
A LITTLE TO THE LEFT OF THE PREVIOUS ADVISORY TRACK AND LIES JUST
TO THE RIGHT OF THE CONSENSUS MODELS TV15 AND TCVA.

MID-LEVEL DRY AIR ENTRAINMENT CONTINUES TO PLAGUE ISAAC. AS SOON AS
THE CYCLONE DEVELOPS INNER-CORE CONVECTION AND THE APPEARANCE OF AN
EYE IN RADAR AND SATELLITE IMAGERY...THE CONVECTION ERODES DUE TO
THE DRY AIR. DESPITE THE FAVORABLE OCEANIC CONDITIONS AND
UPPER-LEVEL OUTFLOW REGIME...ISAAC ONLY HAS ABOUT 12-18 HOURS FOR
FURTHER STRENGTHENING TO OCCUR. THE OFFICIAL INTENSITY FORECAST IS
SIMILAR TO THE PREVIOUS ADVISORY...WITH ONLY TIMING ADJUSTMENTS
MADE TO THE INTENSITY FORECAST...AND CLOSELY FOLLOWS THE INTENSITY
MODEL CONSENSUS.

ISAAC IS A LARGE TROPICAL CYCLONE. A DANGEROUS STORM SURGE...HEAVY
RAINFALL...AND STRONG WINDS EXTEND WELL AWAY FROM THE CENTER AND
ARE EXPECTED TO AFFECT A LARGE PORTION OF THE NORTHERN GULF COAST.
FOR THIS REASON...IT IS IMPORTANT NOT TO FOCUS ON THE EXACT CENTER
LOCATION. THE THREAT OF HEAVY RAINFALL AND FLOODING IS ALSO
EXPECTED TO SPREAD INLAND OVER THE LOWER MISSISSIPPI VALLEY REGION
DURING THE NEXT FEW DAYS.

HURRICANE ISAAC DISCUSSION NUMBER 32
NWS NATIONAL HURRICANE CENTER MIAMI FL AL092012
1000 PM CDT TUE AUG 28 2012

ISAAC PASSED OVER THE MISSISSIPPI RIVER DELTA IN EXTREME SOUTHEAST
LOUISIANA AROUND 2345 UTC. SINCE THAT TIME...THE CENTER HAS
WOBBLED WESTWARD AND HAS MOVED BACK OVER WATER. A NORTHWESTWARD
MOTION HAS RECENTLY RESUMED AND A SECOND LANDFALL SHOULD OCCUR
LATER TONIGHT NEAR GRAND ISLE. DATA FROM NOAA AND AIR FORCE
RESERVE HURRICANE HUNTER AIRCRAFT INDICATE THAT THE MINIMUM
PRESSURE HAS CONTINUED TO GRADUALLY FALL AND IS NOW 968 MB. THE AIR
FORCE RESERVE AIRCRAFT HAS MEASURED A PEAK 850-MB FLIGHT-LEVEL WIND
OF 96 KT AND BIAS-CORRECTED SFMR WINDS OF AROUND 65 KT. BASED ON
THESE DATA...THE INITIAL INTENSITY REMAINS 70 KT. LITTLE CHANGE IN
STRENGTH IS EXPECTED DURING THE NEXT 12 HOURS OR SO AS THE CENTER
MOVES ACROSS THE BAYOUS OF SOUTHEASTERN LOUISIANA. STEADY
WEAKENING SHOULD COMMENCE LATER WEDNESDAY AS THE CENTER MOVES
FARTHER INLAND.

SMOOTHING THROUGH THE WOBBLES DURING THE PAST FEW HOURS...THE LONGER
TERM MOTION ESTIMATE IS 310/7 KT. ISAAC IS EXPECTED TO MOVE SLOWLY
NORTHWESTWARD DURING THE NEXT 24 TO 36 HOURS AS A MID-LEVEL RIDGE TO
THE NORTHWEST OF THE CYCLONE SLIDES EASTWARD. AS THE RIDGE MOVES
ACROSS THE OHIO VALLEY AND INTO THE MID-ATLANTIC REGION...THIS
SHOULD CAUSE ISAAC TO TURN NORTH-NORTHWESTWARD AND NORTHWARD IN A
COUPLE OF DAYS. AFTER THAT TIME...THE CYCLONE IS EXPECTED TO TURN
NORTHEASTWARD AS IT ENTERS THE MID-LATITUDE WESTERLY FLOW. THE
GLOBAL MODEL GUIDANCE HAS BEEN SHIFTING WESTWARD DURING THE PAST
COUPLE OF RUNS...AND THE NHC FORECAST HAS BEEN ADJUSTED IN THAT
DIRECTION.

BECAUSE OF THE SLOW MOTION OF ISAAC...A PROLONGED PERIOD OF STRONG
WINDS AND HEAVY RAINFALL ARE EXPECTED OVER A LARGE PORTION OF THE
NORTHERN GULF COAST. THE THREAT OF HEAVY RAINFALL AND FLOODING IS
ALSO EXPECTED TO SPREAD INLAND OVER THE LOWER MISSISSIPPI VALLEY
REGION DURING THE NEXT FEW DAYS.

NATIONAL OCEAN SERVICE TIDE GAUGES INDICATE THAT STORM SURGE HEIGHTS
OF 6 TO 10 FEET ARE OCCURRING ALONG PORTIONS OF THE COAST OF
SOUTHEASTERN LOUISIANA AND MISSISSIPPI. GIVEN THE LONG DURATION
OF ONSHORE FLOW IN THESE AREAS...WATER LEVELS ARE EXPECTED TO REMAIN
HIGH FOR THE NEXT 12 TO 24 HOURS.

------------------------------
AT 1000 PM CDT...0300 UTC...THE CENTER OF TROPICAL STORM ISAAC WAS
LOCATED NEAR LATITUDE 30.3 NORTH...LONGITUDE 91.2 WEST. ISAAC IS
MOVING TOWARD THE NORTHWEST NEAR 6 MPH...9 KM/H. THIS GENERAL
MOTION IS EXPECTED TO CONTINUE THROUGH TONIGHT...FOLLOWED BY A TURN
TOWARD THE NORTH-NORTHWEST BY THURSDAY NIGHT OR EARLY FRIDAY. ON
THE FORECAST TRACK...THE CENTER OF ISAAC WILL MOVE FARTHER INLAND
OVER LOUISIANA TONIGHT AND TOMORROW...AND MOVE OVER SOUTHERN
ARKANSAS THURSDAY NIGHT OR EARLY FRIDAY.

MAXIMUM SUSTAINED WINDS ARE NEAR 60 MPH...95 KM/H...WITH HIGHER
GUSTS. THE STRONGEST WINDS ARE PRIMARILY OCCURRING OVER WATER OR
NEAR THE COAST. STEADY WEAKENING IS EXPECTED DURING THE NEXT 48
HOURS AS ISAAC MOVES INLAND. ISAAC IS FORECAST TO BECOME A TROPICAL
DEPRESSION ON THURSDAY.

TROPICAL STORM FORCE WINDS EXTEND OUTWARD UP TO 175 MILES...280
KM...PRIMARILY OVER WATER TO THE SOUTHEAST OF THE CENTER. A
SUSTAINED WIND OF 45 MPH WITH A GUST TO 56 MPH WAS RECENTLY
REPORTED IN MANDEVILLE LOUISIANA.

THE ESTIMATED MINIMUM CENTRAL PRESSURE BASED ON NEARBY SURFACE

HAZARDS AFFECTING LAND
----------------------
EVEN THOUGH ISAAC IS NO LONGER A HURRICANE...LIFE-THREATENING
HAZARDS FROM STORM SURGE AND INLAND FLOODING ARE STILL OCCURRING.

STORM SURGE...THE COMBINATION OF A STORM SURGE AND THE TIDE WILL
CAUSE NORMALLY DRY AREAS NEAR THE COAST TO BE FLOODED BY RISING
WATERS. THE WATER COULD REACH THE FOLLOWING DEPTHS ABOVE GROUND IF
THE PEAK SURGE OCCURS AT THE TIME OF HIGH TIDE...

* MISSISSIPPI AND SOUTHEASTERN LOUISIANA...5 TO 10 FT
* SOUTH-CENTRAL LOUISIANA...2 TO 4 FT
* ALABAMA...2 TO 4 FT
* FLORIDA PANHANDLE AND APALACHEE BAY...1 TO 2 FT

THE DEEPEST WATER WILL OCCUR ALONG THE IMMEDIATE COAST IN AREAS OF
ONSHORE WINDS. SURGE-RELATED FLOODING DEPENDS ON THE RELATIVE
TIMING OF THE SURGE AND THE TIDAL CYCLE...AND CAN VARY GREATLY OVER
SHORT DISTANCES. FOR INFORMATION SPECIFIC TO YOUR AREA...PLEASE
SEE PRODUCTS ISSUED BY YOUR LOCAL WEATHER SERVICE OFFICE. NEAR THE
COAST...THE SURGE WILL BE ACCOMPANIED BY LARGE AND DANGEROUS WAVES.

A STORM SURGE OF AROUND 6 FEET IS STILL OCCURRING AT WAVELAND
MISSISSIPPI AND A SURGE OF 6 FEET HAS RECENTLY BEEN OBSERVED AT A
NATIONAL OCEAN SERVICE TIDE GAUGE AT NEW CANAL STATION ON THE
SOUTH SHORE OF LAKE PONTCHARTRAIN.

WIND...TROPICAL STORM CONDITIONS WILL CONTINUE ACROSS THE WARNING
AREA THROUGH THURSDAY MORNING.

RAINFALL...ISAAC IS EXPECTED TO PRODUCE TOTAL RAINFALL AMOUNTS OF
7 TO 14 INCHES...WITH POSSIBLE ISOLATED MAXIMUM AMOUNTS OF 25
INCHES...OVER MUCH OF LOUISIANA...SOUTHERN AND CENTRAL
MISSISSIPPI...SOUTHWEST ALABAMA AND SOUTHERN AND CENTRAL
ARKANSAS THROUGH FRIDAY. THESE RAINS COULD RESULT IN SIGNIFICANT
LOWLAND FLOODING.

TORNADOES...ISOLATED TORNADOES ARE POSSIBLE ALONG THE CENTRAL GULF
COAST REGION AND PARTS OF THE LOWER MISSISSIPPI RIVER VALLEY
THROUGH THURSDAY.

SURF...DANGEROUS SURF AND RIP CURRENT CONDITIONS WILL CONTINUE TO
AFFECT THE WEST COAST OF FLORIDA AND THE NORTHERN GULF COAST FOR THE
NEXT DAY OR SO.
