Isaac Could Bring 2-4" of Rain to Metro Area
While not officially announced by the NHC, latest hurricane hunter reports show Isaac is now of suffcient strength to be Hurricane Isaac and I believe the 10 a.m. update will reflect that.
Isaac is headed toward the mouth of the Mississippi River and the coast of Louisiana with winds of 75 mph and is moving at 7 mph. Isaac's forward motion has slowed considerably since the 5 a.m. update which doesn't bode well for Louisiana at all. Isaac is currently located about 120 miles from the mouth of the Mississippi River, so at this pace, it won't make landfall for another 12 hours or so.
DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
AT 700 AM CDT...1200 UTC...THE CENTER OF TROPICAL STORM ISAAC WAS LOCATED NEAR LATITUDE 27.8 NORTH...LONGITUDE 88.2 WEST. ISAAC IS MOVING TOWARD THE NORTHWEST NEAR 7 MPH...11 KM/H...AND THIS GENERAL MOTION IS EXPECTED TO CONTINUE FOR THE NEXT DAY OR TWO WITH SOME FLUCTUATIONS IN FORWARD SPEED. ON THE FORECAST TRACK...THE CENTER WILL BE NEAR OR OVER THE LOUISANA COAST TONIGHT OR EARLY WEDNESDAY. MAXIMUM SUSTAINED WINDS ARE NEAR 70 MPH...110 KM/H...WITH HIGHER GUSTS. STRENGTHENING IS FORECAST...AND ISAAC IS LIKELY TO BECOME A HURRICANE LATER TODAY. ADDITIONAL STRENGTHENING IS FORECAST UNTIL THE CENTER MOVES INLAND. TROPICAL-STORM-FORCE WINDS EXTEND OUTWARD UP TO 205 MILES...335 KM FROM THE CENTER.
HAZARDS AFFECTING LAND
----------------------
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...
* SOUTHEAST LOUISIANA AND MISSISSIPPI...6 TO 12 FT
* ALABAMA...4 TO 8 FT
* SOUTH-CENTRAL LOUISIANA...3 TO 6 FT
* FLORIDA PANHANDLE...3 TO 6 FT
* FLORIDA WEST COAST INCLUDING APALACHEE BAY...1 TO 3 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.
WIND...
TROPICAL STORM CONDITIONS ARE EXPECTED TO REACH THE NORTHERN GULF COAST IN THE HURRICANE WARNING AREA THIS MORNING...WITH HURRICANE CONDITIONS EXPECTED BY THIS AFTERNOON. TROPICAL STORM CONDITIONS ARE EXPECTED TO SPREAD NORTHWARD INTO THE FLORIDA BIG BEND AREA AND THE FLORIDA PANHANDLE IN THE TROPICAL STORM WARNING AREA THIS MORNING. TROPICAL STORM CONDITIONS ARE EXPECTED WITHIN THE TROPICAL STORM WARNING AREA IN LOUISIANA BY TONIGHT. TROPICAL STORM CONDITIONS ARE POSSIBLE ON THE COAST OF SOUTHWESTERN LOUISIANA AND THE UPPER TEXAS COAST BY TONIGHT OR EARLY WEDNESDAY.
RAINFALL...
ISAAC IS EXPECTED TO PRODUCE TOTAL RAINFALL AMOUNTS OF 7 TO 14 INCHES...WITH POSSIBLE ISOLATED MAXIMUM AMOUNTS OF 20 INCHES...IN SOUTHEASTERN LOUISIANA...SOUTHERN MISSISSIPPI... SOUTHERN ALABAMA...AND THE EXTREME WESTERN FLORIDA PANHANDLE. THESE RAINS COULD RESULT IN SIGNIFICANT LOWLAND FLOODING. TORNADOES...TORNADOES MAY OCCUR ALONG THE NORTHERN GULF COAST TODAY. SURF...DANGEROUS SURF AND RIP CURRENT CONDITIONS WILL CONTINUE TO AFFECT THE FLORIDA COASTLINE AND PORTIONS OF THE NORTHERN GULF COAST FOR THE NEXT DAY OR SO.
------------------------------------
For us, the main threat is going to be heavy rain. Here's the latest from the Hydrometeorological Prediction Center:
------------------------------------
CONVECTIVE CHANCES SHOULD INCREASE THIS PERIOD FROM NC SOUTHWARD INTO NORTHERN GA..SC AS COLD FRONT SLIPS SLOWLY SOUTHWARD ACROSS THE REGION AND INTERACTS WITH PLUME OF VERY HIGH PWS FEEDING NORTHWARD INTO THE BOUNDARY IN DEEP LAYERED CONFLUENT REGION BETWEEN ISAACS CIRCULATION AND WESTERN PERIPHERY OF WESTERN ATLANTIC RIDGE. WITH PWS EXPECTED TO EXCEED 2.25 INCHES AND MODELS SHOWING INCREASING RIGHT ENTRANCE REGION JET DYNAMICS THAT COULD BE ENHANCED BY OUTFLOW FROM ISAAC...FEEL POTENTIAL FOR SOME SLOW E/W TRAINING BANDS OF HEAVY RAIN WILL BE POSSIBLE..ESPECIALLY FROM NE GA EWD INTO SRN NC..WHERE GENERALLY 1 TO 2 INCH PLUS RAINS WILL BE POSSIBLE WITH ISOLATED HEAVIER AMOUNTS OVER 4 INCHES OR SO GIVEN TROPICAL AIRMASS.
-----------------------------------
The NWS here in Atlanta is calling for 2-4" of rain between now and Friday with some isolated areas receiving more. The first band of rain is located between Atlanta and Macon and moving north. 2" has already fallen in some of those areas with more to come. Precipital water values are in the 2.2"-2.3" range (notice how thick the air feels?) so when it does rain, it will be a tropical rain and it comes down hard and fast. Ponding on the roadways will be an issue. Our 3 hour flash Flood Guidance shows that we can get about 3" or so before flooding becomes an issue.

Meteorologist are discussing why the NHC didn't upgrade Isaac to a hurricane at the 10am update. The vast majority feel like it should have been upgraded. The thought is that the NHC will wait until the 2pm update to do it and also adjust the forecast track at that point.
We are getting feeder bands of rain in the Atlanta metro area right now and this band might stall out of the area for a while this afternoon as it interacts with a stationary front located over north Georgia. Expect this rain to continue most of the afternoon. Rainfall amounts over Georgia have already exceeded 3" in some locations so please be careful when driving on the streets and roads.

This from the NWS office this morning regarding our weather today and tomorrow:
-------------------------------------------
MAIN PROBLEM IN THE SHORT TERM IS COVERAGE AND TIMING OF SHRA/TSRA.
RICH MOISTURE FROM ISAAC CONTINUES TO STREAM EAST FROM THE CENTER
OVER THE STATE WITH WEAK FRONTAL ZONE OVER NORTH GA GOING NOWHERE FAST. VERY FAVORABLE WAA (Warm Air Advection) PATTERN IN LOW LEVELS WILL ALLOW FAIRLY WIDESPREAD SHRA WITH SOME TSRA TO DEVELOP BY MIDDAY. RAINFALL COULD BE HEAVY WHERE IT OCCURS BUT ACCUMULATIONS AT ANY ONE SPOT SHOULD REMAIN NO GREATER THAN AN INCH WITH LOCALLY HIGHER AMOUNTS. TOTAL RAINFALL THROUGH FRIDAY SHOULD NOT EXCEED TWO INCHES AT ANY ONE SPOT. MODELS IN PRETTY GOOD AGREEMENT ON COVERAGE TODAY. AFTER FAIRLY QUIET NIGHT WITH LOSS OF INSOLATION...SIMILAR PATTERN EXPECTED THURSDAY WITH RICH MOISTURE AND NEARBY FRONT.

So let me get this straight…Hurricane Isaac comes into the US at the Gulf of Mexico near New Orleans. He then proceeds north and does a complete loop across the Midwest. Then, somehow a piece of himself breaks off and moves south down Alabama back to the Gulf of Mexico. Now this piece could become a major storm again and be named Nadine?
I need an explanation, where is our weatherman? Is he still in Cornhusker land?
North Georgia Weather
11:02 pm on Wednesday, September 5, 2012
LOL!!! Yes, I'm still in Cornhusker land and headed back to Atlanta tomorrow!
Isn't weather fun! Yes, Isaac made a big circle around a high pressure center and decided to plop back in the Gulf. And guess what? This is what we have now.
TROPICAL DEPRESSION THIRTEEN DISCUSSION NUMBER 1
NWS NATIONAL HURRICANE CENTER MIAMI FL AL132012
500 PM EDT MON SEP 03 2012
THE SMALL LOW PRESSURE SYSTEM LOCATED OVER THE CENTRAL
ATLANTIC...WHICH DEVELOPED FROM AN UPPER-LEVEL TROUGH...HAS
GRADUALLY ACQUIRED ENOUGH ORGANIZED DEEP CONVECTION TO BE
CLASSIFIED AS A TROPICAL DEPRESSION. VISIBLE SATELLITE IMAGERY AND
AN EARLIER ASCAT PASS INDICATED THAT THE LOW HAS A WELL-DEFINED
CENTER AND RELIABLE WINDS OF AROUND 25 KT. THE INITIAL INTENSITY IS
SET A LITTLE HIGHER AT 30 KT SINCE ASCAT HAS A KNOWN LOW BIAS AND
BECAUSE THE RESOLUTION OF THE INSTRUMENT LIKELY CAN NOT RESOLVE THE SMALL RADIUS OF MAXIMUM WINDS.
THE DEPRESSION IS FORECAST TO MOVE SLOWLY WEST-NORTHWESTWARD AROUND
THE SOUTHWESTERN PORTION OF A RIDGE OVER THE EASTERN ATLANTIC
DURING THE NEXT 24 HOURS. AFTER THAT TIME...THE CYCLONE IS
EXPECTED TO TURN NORTHWARD AS THE WESTERN PORTION OF THE RIDGE
ERODES.

That's great Jim! When I took my class, I had to go over to Winder, there was nothing around here in this area. I think Kristi took the class also!
I'm also a part of the Spotter Network. http://www.spotternetwork.org/
Their training is a little more rigorous than the NWS class and very thorough. If you liked the NWS training, I think you'll like this too.
