I'm surprised looking at the webcams just how many people and cars are still out and about, even as close as the estimated landfall within 12hr from now. Once those outer-bands get passing overhead things are only going to deteriorate with each passing hours.

Ah well. I'll just add the link. Amazing looking speed up in the eye wall rotation at the end of the animation here

Even if it doesn't it will b catastrophic either way 

It's going to be a very close call

I saw this earlier on Twitter, the lightning inside Laura!

There's a larger, better quality version on my twitter page, but here's the animation I was trying to post.
EDIT: It's the speed up in rotation near the end that's just

They only seem to open in a fresh tab

[toggerob]

This video was filmed during Irma as an example and those winds aren't even close to eyewall strength.

Clear your cookies, or history, everything OK here.

Couple of points:

1: NO hint of any EWRC at the moment, no obvious moat nor any double wind maxima showing. Suggests the inner core is still tightening up.

2: Thus far no obvious signs of any mid level shear. Its a close call as to whether it impacts Laura before it makes landfall as there was observed earlier today near the coast. Can;t rule out some shear on this just before landfall but its a borderline call.

3: The latest dropsonde has winds around 135kts+ literally a few hundred feet above the surface, with 155kts around 900hpa. To me in my experience, would suggest gusts could well get into that 135-155kts range in the strongest eyewall convection on the Right Front Quadrant. IF Laura undergoes any further deepening those 135+ winds likely to be dragged to the surface and a category-5 at that point becomes very probable.

4: Turn NNW now started. IMO any error will be to the east from this point onwards.

All seems to be working now. Temporary glitch it appears

Yes max recorded at the moment is 145-150MPH so 7 MPH short of CAT 5..

The update at 5pm central will be CAT 4 however that gives us a 3 hour window until the 8pm NHC update. Thats the timeline for CAT 5..

Mid level shear increases post then really so very much close to the wire - pretty irrelevant I guess > just for numbers sake I guess.

Next recon is probably going to be do or die on that front, especially with the risk of some shear possibly just starting to impact from that point onwards may just prevent any further strengthening past 00z. Something to keep an eye on.

Regardless this is likely going to be one of/the strongest hurricane to ever impact this region and a high cat-4 is going to be very destructive.

More Recon on the way.

Still 30% chance of CAT 5 > we need about 3-4 more hours of steady deepening....

When is it forecast to make landfall our time

[summer blizzard]

Around 9am.

The 5pm Edit is 145 MPH / 947 MB.

The forecast is 150MPH / 130 KT > just 7 MPH shy of CAT 5 > but theres enough variable there to still be on the margin... we would need 160 MPH because of rounding.

Even at 145mph it pretty ranks up there on its own. Makes it the 3rd strongest USA landfalling hurricane since Andrew, only behind Hurricane Michael of 2018 and Charley.

150mph makes it joint 2nd with Charley.

Michael took quite a few months before they finally awarded the Cat5 certificate....
