Hurricane Alex. 40 Miles NNE of La Pesca. 100 MPH/948MB

[Scott747]

latest visible satellite looks like alex is moving NNW

I asked previously how you are basing these movements.

Eyeballing or coordinates?

[Stormrider]

I still say a range of tall mountains decoupling the low level circulation from the mid-level circulation happens. Remember 1994, and East Pac Hurricane Rosa. The surface low didn't cross the mountains, the mid level low and tropical moisture slug did, and moved over a shallow cold layer of air over Texas and rained like crazy.

So, assuming that this has happend, could a new circulation form?

We have a center folks. There is some mid level spin SW of the center. HI RES VIS Imagery clearly showed this before night fall.

I don't know. Doesn't seem to happen much I can remember. Might be a pro-met question, beyond my non-pay grade.

No prob, Ed. You're smarter than the average bear...watcher!

The VM is this is TS Alex again...and it aint wasting time....

[srainhoutx]

Some assistance from the night crew for the full package update and intermediate advisories would be appreciated in the NHC Outlook thread. Big night ahead.

I was watching TWC a little while ago and did a double-take when their track showed Alex landing ashore with wind speeds of only 25 mph. Then, I read a blog that said that the further north the system goes, the more wind shear and drier air it might encounter, inhibiting opportunities for further intensification. So I am left wondering, do the pros here think that this system could spend three or four days in the warm GOM and still come ashore at only TD strength?

and the pressure confirmed with the second pass is typically associated with a strong TS or weak hurr. obviously that's only a general case and windspeed depends on the gradient, not the absolute pressure, but it's certainly encouraging to have an LP that deep after the crossing.

i'm hopeful for the d-max tonight... nice tower appears to already be going up close to the CoC on the east side.

The TWC?? please look to the NHC for updates....the TWC is crap since Lyons left....

Night crew will be here....I have got 3 shiners down me...its going to be a fun night...

Duly noted on TWC, which is why I paid a little more attention after reading the blog entry (Jeff Masters). As of earlier this afternoon, he was only giving a 10% chance of this becoming a major hurricane.

Hopefully wxdata has a ball of string and bailing wax ready...

Dr Masters is a good as they come...I respect him along side Neil Frank....Speaking of Frank....isnt time to bring him out of retirement for this?

Sounds like a fun night I know 2k is going to be on fire! It is going to be a long day at work tomm.

FWIW -

Even though I won't be chasing Alex unless it were to become a threat to the upper Texas coast as a major...

Just recently had a long talk with my chase partner (Josh) and if I were to be chasing, I'd be making plans right now to head towards Mexico and across the border tomorrow afternoon. It's not so much a landfall projection point as it is making plans to establish a base with the potential to quickly move.

As always that could quickly change in the next 12 to 24 hours.

Chewing gum and duct tape- works every time. If push comes to shove, I guess we could always fire up the old board (gag...)

[srainhoutx]

Perhaps Scott can get Josh to rejoin us as he was a member of the 'old board'. Many enjoyed your adventures of Dolly and Gustav. We all were a just bit busy to fully enjoy Josh's Ike intercept.

I actually checked it out yesterday for a link but man was it slow.


Speaking of that do y'all need donations? Would that help sustain the forum during high traffic and bandwidth periods?
