Re: ATL: H Dolly in Western Gulf of Mexico
Ill ask again...is this forecast to slow down further?
And it looks like its continuing to go north of forecast...this is going to be a big problem for the texas coast, especially if it slows down even further, which might give it up to 20 hours left.

Radar and satellite presentations must be deceiving, because they surely do not look to show a motion of 305. As Avila states, it is important not to follow the line. Everyone in the cone should pay very close attention.
I'm in Corpus and I'm watching Dolly's every move, lol

I agree hsvwx there is every chance if the convection continues to explode like it has done (cloud tops close to -90C!!!) and the eyewall continues to wrap around and eentually totally closes off then I have no reason to think that we can't make it to cat-2, esp if the current rate of deepening over the last 9-12hrs can continue.

Yes, I reduction in forward speed is expected as Dolly approaches an area of weak steering currents before the suptropical ridge builds back in forcing Dolly westward. It will be interesting to see when that subtropical ridge builds in. With the alignment of Texas' coastline, it makes all the difference in the world for a landfall of Brownsville or one for Corpus Christi.

Wow well if that happems Dreeze it would be pretty scary stuff, we will have to wait and see but at least in the short term I see no reason why that sor tof strengthening can't continue to occur.
RL3AO, you can really see the deep convection there with Dolly and the eyewall is looking good, also some cells moving towards Texas it seems in the next 6hrs.

landfall looks slap bang on the border of Mexico and Texas, Bro. would get hammered if that hpapened by the western eyewall which is pretty explosive in terms of convection right now.
from the 500pm discussion:
DOLLY IS MOVING TOWARD THE NORTHWEST OR 305 DEGREES AT 9 KNOTS.
THIS GENERAL TRACK SHOULD CONTINUE FOR THE NEXT 24 HOURS WITH A
SMALL DECREASE IN FORWARD SPEED....
MOST OF THE TRACK MODELS ARE IN GOOD AGREEMENT
BRINGING THE CORE OF DOLLY INLAND IN ABOUT 24 HOURS.
If it slows down as the NHC predicts and keeps the current rate of intensification then...yuck!!!
24hr * 1.25mb/hr = 30 mb drop
= 956 mb ~ 121 mph

Thanks and I agree with you about when the ridge builds back...if it doesnt build back in time then things dont look good!

Do you all think it will continue to slow down?
storms always do strange things before landfall....needs just to go in and die

hsvwx, yeah indeed if it slows down then it also has more time to strengthen yet further as well, mind you the models I've seen slow this way down right by the coast.
Still if it does slow down and keeps uop this current set-up I can well see this getting into the category-2 range as you reckon as well, Derek Ortt just said this could make it to 100mph before landfall.

Taking the 12Z GFS as the "truth", this thing almost stalls right off the coast!

Re: ATL: H Dolly in Western Gulf of Mexico
If it were to stall off the coast, I know that would give it more time to strengthen, but wouldn't it also cause upwelling and perhaps cause the opposite to happen?

Re: ATL: H Dolly in Western Gulf of Mexico
I believe someone already posted the 00Z SPC WRF product, but it seems to have done a marvelous job with its forecast for the hurricane today, and has it moving at about 340 at 12Z tomorrow headed towards Corpus Christi. It also has an improving hurricane structure through the end of its run. It will certainly be interesting to see how this plays out. Anyone within NHCs cone should be just about finished making all the preparations to protect life and property. All one has to do is point at Hurricane Charley to see that conditions at landfall can change drastically even within a few hours! And we are still 16-20 hours away from landfall!
