ATL: ISAAC - Post-Tropical - Discussion

[bonjourno]

Hello all. I'm a long-time lurker from around Gainesville, FL who just decided to register. Eagerly awaiting the latest on this perplexing storm.

Not terribly surprisingly, haven't really felt anything from Isaac around here. Sun gave way to clouds around 5pm here and a couple of tiny bands of showers have passed but that's about it. I think the wind's struggled to even break 15mph

CDO is sprouting its own outflow.

LOL! Three of us in Lauderdale. This is quite definitely the worst so far! It's been bad since nightfall, huh?

Wow, yeah, some really impressive band going through your area. Hang in there!

Thanks, Bud. For reference, I am JUST to the north of the little plus sign (marking Fort Lauderdale) on the KAMX radar if you go through the Miami NWSFO.

Hopefully it slacks off now.

Why is no one on TV weather talking about the trough that is/was supposed to have such an influence on Isaac's landfall point? Anyone know?

I've asked about this once or twice with no answers. Aric linked the WV loop but I can't decipher where it was supposed to be.

Its on the southern end of the convection, but with the way the MLC looks, I would maybe look for relocation under the CDO

Getting slammed with heavy, heavy rain and wind in Port St. Lucie. The rain was gone for a while but has come back with a vengeance. Stay safe fellow South Floridians...It's getting ugly out there and we are seeing what Isaac can do when he decides to flex his muscle. On the lookout for twisters here in PSL.

Worst squall line of the day for sure....easily seen sustained t.s. winds with gusts over 50 mph for last 15 or 20 minutes non-stop

we lost a small tree in the backyard with the last squall and I see the one in Ft. Lauderdale is moving our way

Watch out Bocadude.. that was a nasty one with thuder and lightening added.

Completely agree-we must be close to each other. Wish I hadn't been so lazy. I have a weather station in the garage I haven't set up!

What Issac looks like now is what I expected it to look like 24 hours ago. Its shape is what I expected however with a tight core of convection with a much boarder outside bands that are disconnected from it. It does appear to be spinning up quickly now...finally. The other big thing is the movement is slower.

Were getting hammered right now.. windows are shaking

rapidscan and radar are both still showing the center is on the extreme southern edge of the convection, and the ULL thats causing the shear doesnt seem to be moving at all, so this is probably close to as strong as its going to get by the looks of it

-personal opinion and not official forecast-

[galaxy401]

I heard that the center maybe reforming in the convection. Is that true or is it still on the south side?

[LSU2001]

Not really worth much but I thought this was a pretty image of Isaac.

It (the upper level trough) is passing well to the north and weakening so it is having much less effect than was originally thought. Instead the Bermuda high is strengthening and expanding westward which is preventing Isaac from turning as much north as originally thought. That is why the models have been shifting the track westward.

[Fyzn94]

The good news i would think is that Isaac is not forecast to reach major status. Maybe not even cat 2. So thats good for sure.

Well.....I've known the gulf to be a haven for the unexpected.....and I'm not saying we WILL see something beyond our expectations, I'm just saying that I, personally, still don't know what to expect.

Now that the storm has entered the Gulf, Isaac definitely does appear more together with some major convection firing around the center, but it still doesn't look quite stacked....YET.

KYW radar is actually showing the center closer to where the deepest convection is (maybe 10-15 miles south). But this isn't reflected at the surface.

[SootyTern]

Lights keep going on and off...unnerving me! it's scary out there right now

LOL! Three of us in Lauderdale. This is quite definitely the worst so far! It's been bad since nightfall, huh?

it is by far the strongest it has been all day in fort lauderdale, i thought it was peaking a few hours ago...wrong

I thought Isaac was pretty much over and done with, too, earlier. Nope...power flickering here for the first time all day. You folks in Lauderdale must be getting pounded!

[Jevo]

Im in NW broward county.. the white circle.... It's actually getting worse now.. We've seen 4 inches in 30 mins.. before this our total was 4 for the day... Wind is a whipping a lots of lightning..

[HurricaneQueen]

I can't believe how much worse conditions are on the East Coast of Florida. It's as if we are in different states. Perhaps we will get it worse with the back end but that doesn't seem likely as Isaac is moving away from the coast. On the other hand we have been hearing all along that conditions would be worse late tonight and through the early morning hours. So far, today has not been much worse than our normal afternoon showers with slightly more wind. Hopefully, it will stay like that. Thankfully, we have not lost our electricity!!!!

Be careful everyone and hopefully, the effects will be minimal.

Ok I see it now. When looking at the loop, now I'm wondering how much the midwest high was supposed to dip down. It's still creeping toward the south.
