Continuous feed of new hot towers more symmetrically around the core suggests more appreciable pressure falls are occurring. Would think winds are 80-85 mph now, with a pressure in the 984-985 range.

The eye is rapidly getting better defined.

Mark you have been a leader on this board for a long time.

Thank you so much for what you do. Your information is timely and right on.

Kinda looking like those WPAC systems that form those thin eyes at early stages of its life. Usually they blow convection at some point and the eye disappears again till its in the 100-110kts range.

Cool presentation though, definitely a shift in organisation recently.

Have been thinking Cat 4 for a day or so but there is a small part of me thinking Cat 5. Purely an educated guess. Michael surprised everyone and went Cat 5.


I don't mean to tie up the board but is there somewhere to watch your chase?

Improved poleward cirrus flow is indicative of lower shear occurring over the storm. looking a lot better in terms of new convection, poleward outflow, and vertical alignment. Structurally this looks much more formidable than it did 3 hours ago.

Nice short drive this time. If it goes south is there a way to a safe place that way?

That’s an oddly large eye. I don’t think I’ve ever seen a cat 1 that looks similar to that.

When a dry slot ends up as an eye. you see this quite a bit in formative significant systems.

Mesos starting to rotate in the eye like feature, it is ramping up.

I think Cat 3 will be the top limit. They just mentioned on the weather channel that there is lots of dry air in the Gulf surrounding Laura. That’s probably why they are also keeping it at as a minimal Cat 3

Yeah probably a legacy of some of the drier air it pulled in earlier. I have seen some WPAC systems that look like this, they usually have a decent convective blow-up at some point which covers it over, but who knows as each system presents differently.

If I had to take a punt at strength, probably a legitimate 115kts, but thats just a guess.

I would guess recon finds a 75-80kt hurricane, pressure in the low 980s. Structure is clearly more vertically aligned now

No there is not unless Beaumont. Am scanning Port Arthur for parking garages but so far no dice. Will go to the coast to explore but then tuck tail for the safety of a parking structure. I never risk the truck it is my two-week survival camp.

I do not post any videos. I just post observations on here because I know the audience is just like me.

That is definitely a possibility. At this time anywhere from Galveston to Lake Charles is definitely in play.

Yea we are prepping I do not want to take any chances. Going to stay home as where I am at flooding is not an issue

Lots of convection firing off in the formative eye, I'd imagine we'll have a closed eye in an hour or so

I agree. Expecting to see the pressure start falling at a decent rate.
