She is barely creeping along...if at all.

At the rate she's crawling toward the shore, Dolly could have 3 or 4 more hours over water.

Yep models nailed this thing, the GFDL also did a good job on strength progging a high level cat-1/low end cat-2 when it was still an invest.

Chacor, well it may not have stalled just that it hasn't moved quickly enough to cross any latitude/longitude...still probably only moving 2-3mph now, models did expect this to occur.

Breaking news----collapsed roof in South Pardre island...

And Dolly did a great job herself. Talk about perseverance!

Amen....

Do you see this being upgraded to a Cat 2?


Should have already been upgraded to a cat 2.

NHC probably had a solid synoptic under which Dolly rode.

Slow motion will probably increase the damage effect on poorly built structures in Brownsville.

Barring a stall or a sudden change in course, it looks like SPI is going to get kicked in the teeth by a direct hit from Dolly. Tons of development on the southern tip of the island since the last major 'cane through there.

Since Dolly has Cat 3 like pressure, I'd bet the wind will catch up somewhat as she makes landfall due to its lumbering pace to the coast.

As it is, there is going to be pretty big wind damage at SPI, Port Isabel, etc. and maybe into Brownsville too.

Then look out for the flooding inland.

I hope RGV residents are hunkered down, they are in for a long, long day I'm afraid.

Right, the NHC goes by the best agreement of the models for their probability cone, correct?


Incorrect. The error cone is simply 2/3 the historical track error. That means that 1/3 of the time the track will fall outside the error cone.

Low category with punch. However Cantore didn't look too bad on TWC. Let the eye get closer.

Well for now at least I would say she has stalled. IMO

It looks like the northern eyewall had opened up on radar.

He looked quite a bit worse earlier, must be a lull.

Agree, this should be (and in my unofficial opinion, it already is) a Cat 2.

In fact, given the storm's pressure and slow movement to the coast, it wouldn't surprise me if winds eventually approach low end Cat 3 threshold.

Didn't say that will happen, only that it wouldn't surprise me given the pressure, which is incredibly impressive for what is still "technically" a Cat 1 storm.

Haven't heard much talk about storm surge - thoughts on potential storm surge issues for SPI and Port Isabel?

Brownsville radar might be having trouble getting all the way through those dense bands near the core. The opening is apparent from the Corpus long range...but they are getting a pretty good band on them as well.

Hopefully this has leveled off for now.

Note: If this were Miami the MIA (or now MFL) radar would have been down for 10 hours already. Props to NWS Brownsville for keeping the radar operational...

Yep very interesting to see 94L that so many thought it was doomed but here it is as a hurricane!

I agree with AFM this really should have been upgraded to categoy-2 esp given the pressure and the radar returns we have seen.

Really is crawling now though its close enough to the shore to still be inland in a few hours anyway.
