ATL: ISAAC - Post-Tropical - Discussion

[bayoubebe]

Don't think it's actually that much farther north of the original center.

I maybe wrong though.

It's a LOT further NW of the old center...by about 60-70 miles. It's a short term motion of about 30 mph. The LLC just got sucked up...

How does this change the track in your opinion?

[Meteorcane]

Not to get too off subject considering a rather large event just transpired with Isaac, but you are right ncweatherwizard I did some more digging and found they usually use the NOGAPS (GFS is backup)

[stephen23]

Am seeing this right on recon? Is it actually stronger now? Did i see 62 flight level winds?

[brunota2003]

Well, now that that issue is settled...850mb and surface winds should be on the increase, since the center is now in place to bring them down.

[Aric Dunn]

it will probably ramp up now if the center is under that high reflectivity.

[WxEnthus]

Whew, Florida is looking like a festival float with all those boxes and colors. Might have passed over the Keys with a breeze and a drizzle but Issac sure is giving the east coast & even inland FL a hard time. Hope everyone is safe tonight. Is there a power outage map for FL? We have one here (VA) that shows real time outages by county.

[cheezyWXguy]

anyone still have that rapidscan IR link?

At 5:29 GMT FL winds were reported at 69 MPH with surface winds of 53 MPH

[Meteorcane]

Yeah the fringe/backside of Isaac has been worse it seems than the earlier feeder bands not much rain here in Central Dade (plenty of wind though certainly have seen some 50+ gusts since midnight) although north of my location there has been considerably more rain and also a tornado threat.

[Aric Dunn]

probably has just alittle more northward reforming/pulled north where recon had the wind shift was still about 10 miles south of the deep tstorms. next pass it should be with it.

So wait...did this LLC actually move that far so quickly? I don't really understand how that could happen. Seems as equally likely that this LLC is an extension of the mid-level circulation toward the surface.

Dropsonde, 990 mb

Saw 70 mph surface wind hunter obs on wunderground....so nearing cane strength perhaps.

its not that it actually moved all at once its reform/being pulled reaction. the vorticity stretches and recoils in a way.

[lester]

Isaac is strengthening...recon just found 989 mbs pressure

[fasterdisaster]

Would not be surprised by a bump to 70 mph in 15 minutes.

Wow at the pressure drop!

[brunota2003]

Dropsonde, 990 mb

With 10 knots of wind means likely 989

[Nimbus]

We have been expecting a relocation up under the convection for about 6 hours now. Wonder how much longer the shear is going to effect the track?

[Aric Dunn]

that may actually be the beginning of an eyewall already starting to develop.

[PTPatrick]

Cloud tos around the satellite "eye" thingy (scientific right) look like they are warming...did it just get choked?
