NHC decides to stick with 60KT in its immediate advisory which is likely published before NE pass reveals hurricane-force winds.

Expect an update statement from the NHC very soon.

As a poster earlier said on the thread, Laira is like Secretriat, she is well and far off to the races there is nothing to stop her or inpede her trek. It is just a matter of just how strong she gets and just where she goes, It will likely maje lahdfall very late tomorrow night into early Thursday morning somewhere from Freeport TX, to Houston/Galveston to the SW Louisiana Gulf region.

All we can now is pray and hope thatt the many millions of people in the path of this potential deadly cyclone are doing everything TODAY necessary to plan, and take action to evacuate if they are told to do so. Also, for those fleeing inland, please bear in mind that Laura will likely retain hurricane strength as far as 100 -150 miles INLAND after landfall during Thursay morning.. So be prepared for likely power outages in those inland areas.


My prayers to everyone staring down this potential beast in the coming days. Prepare for the very worse! Pray and hope for whatever the best of this dire situation God can bring to this entire region!!!

God Speed######

Good morning Jax, those power outages will go to Tennessee! This one will cause extensive widespread damage and massive disruption of millions of lives. Remember Michaels winds reached all the way to Atlanta! Thanks for your posts, we all appreciate the info especially from a N FL local!

Yeah I did not take .more into account the expansive wind field Laura will have. It will cover much of the Lower and Mid Mississippi River Vallety, and of course the path will carry it into across the Tennessee River Valley to the Mid-Atlatic. A very large swath indeed. So many millions of people potentially are going to be impacted.


So, many peoole have to really make the necessary actions to prepare. This is as dire a situation can get in such a short term period!!

The highest ensembles are showing 160kt+ and sub-900mb. Impressive.

NHC just upgraded Laura to hurricane.....MGC

[aspen]

Laura’s pressure gradient is much tighter this morning than it was last night. Winds are still light on the western side of the storm, but with an eyewall almost complete, they should start picking up later today.

That was fast! I would have done it on the last advisory 23 minutes ago.

[SconnieCane]

Some of those Euro runs...

If Bolivar gets wiped clean again just 12 years after Ike, I don't see how anyone in their right mind rebuilds there.
