Tropical Major Hurricane Laura

[Tarheel1]

If Laura misses Cuba all together, or just grazes the Southern edge, somebody better look out on the Gulf coast

 

[jackendrickwx]

Pressure is down to 998.4 mb.

What was it previously?

What was it previously?

1004mb

 

[GaWx]

929 mb just east of Galveston

The 929 mb of the 12Z HWRF is likely much too low based on bias and that it may not even be taking into account Marco's wake. Does the HWRF for Laura even know that Marco exists? The 1001 mb Euro seems ridiculously too high because it is likely just out to lunch and assuming too much land interaction.

Let's see: (929 +1,001)/2 = 965 mb.. I'm going with that as a first guess with a likely range of 955-975 mb.

If this thing is only a TS in the Gulf I'll be nothing short of shocked look at the structure this is supposed to be it's weakest given it went over Hispanola lol

 

[Tarheel1]

TWC ( I know?) keeps hyping Laura a pretty good bit. Hedging their bets on a Cat 2 landfall now, with “potential to be a lot stronger”

Hispaniola imo is somewhat overrated as far as how much it degrades storms. As I assume you know, a relatively weak and poorly organized storm at the surface like Laura was as it first went over the island (a "mess" as some were calling it) can go over the island and hardly weaken as there is still plenty of surrounding very warm water keeping the overall atmosphere supportive. Also, Laura has always had a much better organization up a few thousand feet vs near the surface. This higher up organization should mean less tearing up by the mountains vs a well organized LLC.

I agree that the Euro's maxing out as a TS seems way off.

According to TWC, 5 people in Haiti has been killed from the storm.

You don’t need a 150mph storm to be deadly, unfortunately

 

[BirdManDoomW]

Would love to see it stay south all the way into the Caribbean the entire length of Cuba then come north strong and go over waters untouched from Marco in eastern gulf

Every single member has it heading NW from initialization, and the storm Is moving due west at this point. Horrible run for Euro.

Throw every one of them out.
