According to this run on the NAM, NOLA will get pounded with rain and storms for 18 hours or mor straight. I hope their new pumps are working!

Although the overall satellite presentation of the depression has changed little this evening...new bands of deep convection have developed to the southeast of the center. Satellite classifications and recent buoy observations support keeping the initial intensity at 30 kt. A NOAA hurricane hunter aircraft is scheduled to investigate the cyclone overnight. A shear analysis from UW-CIMSS shows about 20 kt of westerly shear over the cyclone. This shear is forecast to relax during the next 12-24 hours as an upper-level anticyclone builds over the Gulf. This is expected to result in a favorable environment for intensification. However...given the large size of the circulation...strengthening is expected to be gradual. The new NHC intensity forecast is nearly identical to the previous advisory and is a blend of the SHIPS/lgem guidance.
The depression has not moved much this evening...and the highly uncertain initial motion is 315/2 kt. Since the depression is still in the formative stage...the center could reform within the large circulation during the next 12-24 hours. This possibility is supported by the GFS...which shows the center reforming farther north within 24 hours. Steering currents are expected to remain weak during the next several days as the depression remains to the south of a weakening mid/upper level ridge. As the ridge slides eastward...it should allow the cyclone to move slowly northward... then northeastward. Although the dynamical models shows little overall motion during the next 2-3 days...there is a large spread in the guidance and lower than normal confidence in the track forecast. The updated NHC track is a little slower and east of the previous forecast.

Sure you didn't mean an different storm? Ike wrecked havoc from my neck of the woods in Texas.
maybe it came from that direction, but it was Ike. One of the big open storm drains flooded badly enough that several houses were bought out by FEMA. We're set up for some pretty heavy rain that we get in the spring which just dumps into the Missouri, the Meramec and the Mississippi eventually, but that storm overwhelmed the system.
I like the path of that rain. Let it be so!

Plodding, erratic Gulf of Mexico storm puts Louisiana on alert
I have been to NOLA during a 15 inch rain. No problem, as their storm pumps will do just fine. It's when the levees give way when NOLA floods. Now the burbs are another issue.
Looks like its gonna miss us NN...
But thanks for your diligence in keeping us informed.

Tropics update: A ton of rain on the way
Very soon to be Lee. Just waiting for the official word.
I always find it puzzling when a comment gets yanked on a thread with a seemingly seemingly innocuous subject such as the weather...
Sometimes the poster request it after they realize they said something stupid or they accidently posted to a wrong thread, happens all the time.
Thanks for the ping NN!
“Send down the rain, Lord, Send down the rain!”
Thankful in Louisiana, but our pecan trees could do without the wind :(
