The episode as NWS JAN wrote it up.
Tropical Depression Nine formed in the Atlantic, east of the Lesser Antilles, on the morning of August 21, 2012. Twelve hours later, Tropical Depression Nine had strengthened into Tropical Storm Isaac. Isaac continued to track through the eastern Caribbean Sea and Florida Straits while maintaining high end tropical storm strength. Just before noon central time on the 28th, Isaac was located about 75 miles south-southeast of the mouth of the Mississippi River(or about 160 miles southeast of New Orleans) and was found to have reached hurricane strength with winds of 75mph. An outer rain band from Isaac brought some showers to portions of the ArkLaMiss during the afternoon of the 28th, while the center of Isaac was still churning in the Gulf of Mexico. At 6:45pm on August 28th, Hurricane Isaac made a brief landfall along the coast of Southeast Louisiana in Plaquemines Parish. Maximum sustained winds were 80mph at this landfall. Isaac did not remain over land for long as he was back over water again by 9:00pm that same evening. Isaac made his second landfall along the coast of southeast Louisiana, just to the west of Port Fourchon, around 2:15am August 29th, again with maximum sustained winds of 80 mph.
Isaac moved very slowly to the north and northwest over the course of August 29th, which made for prolonged impacts. Forward motion of about 5 mph lead to tremendous flooding issues for both Louisiana and portions of Mississippi south of I-20. Around noon on August 29th, Isaac was downgraded to a Tropical Storm, but this was not much relief to the many residents who were being inundated with rain and wind. Storm total rainfall across portions of Marion County indicated at least 10 to 15 inches fell. Numerous homes and buildings were flooded and some water rescues occurred in Lamar, Marion and Clarke counties. Further to the north, flooding issues were not quite as bad with about 5 to 7 inches of rain falling from the I-20 corridor and north. Tropical storm force wind gusts were noted as far north as Bolivar County, with the Golden Triangle region not seeing winds reach more than tropical depression strength. The worst of the wind was felt generally along and south of an axis from Marion County to Adams County. Numerous trees were down in Adams County, leaving many without power for several days. Eighty percent of the roads were blocked in Franklin County due to downed trees.
With all of the rain that fell, some of the area rivers filled quickly. Minor flooding was recorded on the lower Pearl River at Rockport and Monticello, as well as on Bouie Creek at Hattiesburg and Tallahala Creek at Laurel. The biggest river impact in the Jackson Hydrologic Service Area was on Black Creek at Brooklyn. Black Creek entered moderate flooding and finally crested at 26.71 feet on August 31st at 5pm. This will go down as the second highest crest in history for this particular river and forecast point. This river flooding caused damage to 15 homes both upstream and downstream of the river gage.
The winds and flooding were not all Isaac brought as a couple of tornadoes touched down in eastern Mississippi. Two tornadoes, one in Clarke County and one in Lauderdale County, occurred during the morning of August 30th. Both were rated EF-1 with winds around 100 mph. The tornado in Clarke County, near Crandall, resulted in 3 injuries to residents of a mobile home. One death attributed to Isaac occurred in Holmes County when a 64 year old woman was killed by a tree falling on her car. Isaac finally moved out of the region by the afternoon of the 30th, and was downgraded to a tropical depression by late afternoon on the 30th as it continued to track to the northwest into Missouri and the Ohio Valley.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
1016 AM CDT TUE AUG 28 2012
.UPDATE...THE FOCUS REMAINS ON ISAAC...AS THE SYSTEM CONTINUES TO
CHURN NWWD. ISAAC HAS SLOWED CONSIDERABLY OVERNIGHT...AND CONVECTION
HAS BEGUN TO WRAP AROUND THE CENTER...HOWEVER IT REMAINS JUST...WITH
ADDED EMPHASIS ON JUST...BELOW HURRICANE STRENGTH. MUCH OF THE
LATEST MODEL GUIDANCE HAS INDICATED AT LEAST SOME WESTWARD SHIFT IN
FORECAST TRACK. THESE TRENDS WILL CONTINUE TO BE MONITORED IN FUTURE
RUNS.
RIGHT NOW ONE OF THE OUTER RAIN BANDS OF ISSAC EXTENDS FROM
BROOKHAVEN TO FOREST TO DE KALB AND IS PIVOTING WESTWARD ACROSS THE
AREA. HAVE INCREASED POPS ACROSS THE CENTRAL PORTION OF THE AREA.
ALSO MADE SOME MINOR ADJUSTMENTS TO HOURLY TEMP/DEWPOINT GRIDS
AND TO KNOCK HIGH TEMPS DOWN IN SOME OF THE AREAS BEING AFFECTED BY
RAIN. FORECAST UPDATES HAVE BEEN SHIPPED OUT. /DL/
&&
.AVIATION...SEEING A BAND OF SHOWERS ON THE FAR PERIPHERY OF ISAAC
PUSHING NORTHWEST THROUGH CENTRAL THIS MORNING. SOME MVFR CONDITIONS
ASSOCIATED WITH THIS BAND EXPECT THROUGH EARLY AFTERNOON FOR A
PERIOD OF AN HOUR OR TWO...MAINLY AFFECT STATIONS
GWO/CBM/GTR/HKS/JAN. OTHERWISE...WE ANTICIPATE INCREASING DECKS FROM
3-5K FEET THIS AFTERNOON AND AN INCREASING RAIN SHIELD FROM THE SE.
CONDITIONS WILL DETERIORATE TONIGHT WITH WIDESPREAD MVFR CONDITIONS
AND INCREASING WINDS AND RAIN...MANY AREAS S OF I-20 DECREASING TO
IFR LEVELS BY SUNRISE WEDNESDAY. 30-40 KT WINDS WILL DEVELOP OVER
SERN ZONES AND SPREAD TO THE WEST AND NORTH DURING THE DAY WEDNESDAY
AS ISAAC LIFTS INLAND. /BB/
&&
.DISCUSSION... /ISSUED AT 527 AM CDT TUE AUG 28 2012/
ISAAC CONTINUES TO GRADUALLY STRENGTHEN AS IT LIFTS ACROSS THE
GULF...BARELY BELOW HURRICANE FORCE AS OF FORECAST PACKAGE TIME AND
EXPECTED TO MAKE LANDFALL AS A CATEGORY ONE HURRICANE NEAR THE MOUTH
OF THE MISSISSIPPI RIVER LATE TONIGHT. A SIGNIFICANT FLOODING THREAT
IS DEVELOPING WITH THIS SYSTEM AS IT MOVES INLAND AND SLOWS ON ITS
TRACK FROM SE LA ACROSS SW MS WED NIGHT AND INTO SE AR ON THURSDAY.
THE FORECAST WILL GENERALLY REFLECT THE THINKING OF THE HPC QPF WITH
10 TO 15 INCHES OF RAIN EXPECTED OVER SERN ZONES THROUGH FRIDAY
MORNING. ALTHOUGH THE EXACT TRAJECTORY OF ISAAC WILL PLAY HEAVILY ON
THE PLACEMENT OF RAINFALL MAXIMA...THIS WOULD SUGGEST AN INCREASING
POTENTIAL FOR HEAVY RAINFALL TOTALS OVER NE LA AND SE AR FOR THE WED
NGT/THU PERIOD WITH A CONTINUING RISK FOR HEAVY RAIN TOTALS OVER MS
ZONES. HAVE EXTENDED THE FLASH FLOOD WATCH AREA SLIGHTLY FARTHER TO
THE NORTH OVER ERN MS AND FARTHER WEST TO INCLUDE MOST OF NE LA.
ALSO EXTENDED IT IN TIME THROUGH WEDNESDAY NIGHT. FURTHER EXTENSION
OF THE WATCH MAY BE NECESSARY FOR LATER PERIODS...ESPECIALLY FOR
NWRN ZONES.
THE TRACK OF ISAAC HAS REMAINED MUCH MORE CONSISTENT OVER THE PAST
FEW FORECAST CYCLES. THE LATEST WIND FIELDS INDICATE A DECENT DEGREE
OF CONSISTENCY WITH THE PREVIOUS PACKAGE. THE TROPICAL STORM WARNING
HAS BEEN EXPANDED TO INCLUDE SECTIONS OF EAST CENTRAL LA AND THE SW
CORNER OF MS...AREAS THAT ARE EXPECTED TO FALL ALONG THE TRACK OF
THE STORM. THE TROPICAL STORM WATCH HAS ALSO BEEN EXTENDED SLIGHTLY
TO INCLUDE RICHLAND PARISH. THESE WATCHES/WARNINGS COULD BE EXPANDED
AND/OR UPGRADED BY LATER SHIFTS IF ISAAC'S TRACK OR INTENSITY
FORECAST CHANGES. ELSEWHERE ACROSS THE CWA NOT IN A TROPICAL STORM
WATCH OR WARNING...GUSTY WINDS WILL BEGIN TO DEVELOP BY WEDNESDAY
AND CONTINUE INTO FRIDAY. SUSTAINED WINDS OF 20-25 MPH WITH HIGHER
GUSTS WILL BE POSSIBLE OVER THE NW AS THE REMNANTS OF ISAAC LIFT
NORTH AND OUT OF THE ARKLAMISS.
YET ANOTHER CONCERN WILL BE THE POTENTIAL FOR TORNADOES EAST OF
WHERE ISAAC TRACKS. THIS POTENTIAL WILL DEVELOP OVER SERN ZONES
THIS EVENING AND FARTHER NWD AS THE STORM LIFTS TO THE N/NW. LATEST
MODELS SUGGEST THAT WEDNESDAY NIGHT AND THURSDAY COULD BE ONE OF THE
BEST TIMES FOR TORNADO DEVELOPMENT AS FAVORABLE LOW LEVEL SHEAR
COMBINES WITH MLCAPE VALUES FORECAST TO INCREASE TO AROUND 1000
J/KG. WITH ISAAC'S EXPECTED TRACK CURRENTLY FORECAST OVER THE FAR
WESTERN PORTIONS OF THE CWA...THIS ESSENTIALLY PUTS MOST OF THE CWA
AT RISK.
THE REMNANTS OF ISAAC WILL CONTINUE THEIR NORTHWARD TREK FRIDAY...
ALLOWING CONDITIONS TO GRADUALLY BEGIN IMPROVING OVER THE ENTIRE
CWA. THE REMNANTS WILL EVENTUALLY GET PICKED UP AND SWEPT EAST OVER
THE OHIO RIVER VALLEY OVER THE WEEKEND AND INTO THE GREAT LAKES
REGION EARLY NEXT WEEK. WITH PLENTY OF MOISTURE LEFT OVER THE
FORECAST AREA IN ISAAC'S WAKE...RAIN CHANCES WILL REMAIN OVER THE
AREA EACH AFTERNOON AND EARLY EVENING THROUGH THE WEEKEND INTO EARLY
NEXT WEEK. 03/19/
