Is this "real" or the high res micro model thing?

Eye pretty much fully closed. Next advisory will be interesting.

So...people are saying the surge has already peaked ... is this accurate ? it's seriously peaked already? :S

I don't know about that...

I thought high tide was early tomorrow morning and the storm is basically pushing water into the bay and will be for 12 more hours...

It's just a radar/satellite image of Issac in its current state. Impressive, isn't it? This storm is overperforming more than I ever imagined it would.

[MHurricanes]

I don't think the folks in Southeast Lousiana were prepared for a slow-moving, intensifying hurricane at landfall. The flooding from Isaac could be a major problem.

[nautical wheeler]

I don't see with my amateur eyes what there is to allow for the forecast NW movement. I realize the models are showing a slow westward movement now but I don't see how it can go much further north with the ridge in place. It looks to me like the path of least resistance is straight left. What is the NHC seeing that will even allow it to go any further north in the next 12-24 hours? Or is this a case of them shifting the track incrementally to the West?

Still 80mph and a pressure of 968.

You need to read/listen to your own local NWS and government emergency offices for that info. It varies widely depending on where you are. Don't trust anyone else!

[Buck]

I'm thankful, but nonplussed as to how this is just an 70kt hurricane.

...ISAAC PRODUCING A DANGEROUS STORM SURGE ALONG THE NORTHERN
GULF COAST...FLOODING FROM RAINFALL TO FOLLOW...


SUMMARY OF 1000 PM CDT...0300 UTC...INFORMATION
-----------------------------------------------
LOCATION...29.0N 89.7W
ABOUT 75 MI...120 KM SE OF HOUMA LOUISIANA
ABOUT 75 MI...120 KM SSE OF NEW ORLEANS LOUISIANA
MAXIMUM SUSTAINED WINDS...80 MPH...130 KM/H
PRESENT MOVEMENT...NW OR 310 DEGREES AT 8 MPH...13 KM/H
MINIMUM CENTRAL PRESSURE...968 MB...28.59 INCHES

Kind of surprised it stayed at 80mph...has there really not been enough recon/land obs evidence to put it higher? I would guess 90mph minimum from the satellite presentation.

[Janie2006]

The comparison between Isaac this morning and Isaac right now is another classic example of how a system can pull itself together in a very short amount of time. And that's why you really can't let your guard down when one of these things is in your neighbourhood.

[catskillfire51]

I don't understand how that could be...I thought I heard it would be worse tomorrow morning at high tide.

tides flood and ebb, some places the cycle is twice a day (semi-diurnal), some places it is once a day (diurnal). but right now the tide is ebbing (going out) so the flood levels have "peaked". tomorrow morning when the flood tide reaches it's high the flood levels will more then likely be higher then they were today.

just my uneducated opinion

[CYCLONE MIKE]

A couple more hours over water and Isaac could make a run at cat 2 IMO. Satellite presentation sure does look like.

Highest surge I can find is at Shell beach, currently at 10.31' and still rising.

[SunnyThoughts]

I keep waiting for this thing to weaken somewhere...instead, it looks better than it has ever looked. Now is when we need the dry air to get in there and disrupt that eye.

[Rail Dawg]

I'm here in Houma and am next to a wind-sock for the hospital helipad. The winds are gusting stronger than ever and it appears the COC is approaching.

[HouTXmetro]

I guess looks can be deceiving... NHC still says Isaac is moving NW at 8mph. Guess the talk of stall and West movement can cease.

[CronkPSU]

NW at 8mph....really?

come on NHC...really?

[Steve]

Making a run for Grand isle/leeville and port fourchon. After that are some incredibly low lying areas in south terrebonne such as montegut, chauvin, dulac, cocodrie, etc.
