Hurricane Hurricane Laura

[akt1985]

Laura is now a Cat 2 with winds of 105 MPH.

 

[Brice]

Laura is now a Cat 2 with winds of 105 MPH.

Only problem is, it's forecasted much worse.

 

[Blountwolf]

I keep thinking I'll go to bed, and then it does things like this.

 

[TCLwx]

Laura now projected by NHC to be a Cat 4 at landfall.

 

[warneagle]

Down to 964. It was 969 an hour ago.

 

[Kory]

Down to 964. It was 969 an hour ago.

That has to be a record or something....

 

[warneagle]

Laura is now a Cat 3 with winds of 115 mph.

 

[warneagle]

That has to be a record or something....

Yeah, the old definition of rapid deepening was 42 mb in 24 hours, so 5 mb in an hour is...yikes.

What’s amazing about this storm is that despite the amount of deepening and pressure drops that has happened only on one advisory did the maximum sustained winds increase by more than 5 mph.

Gulf storms seem to take a while to respond to pressure falls. I remember Hurricane Isaac in 2012 landfalled in Louisiana at 965mb. It only had sustained 85mph winds which is unusually low for that pressure.

 

[Kory]

Yep, a historic storm.

 

[warneagle]

Yep, a historic storm.

Is there a correlation between eye diameter and intensification?

 

[Kory]

Is there a correlation between eye diameter and intensification?

Yes inverse relationship. Smaller eye diameter can deepen more rapidly. Latest recon indicates a 28nm eye which is pretty big. It has been contracting which indicates strengthening.

 

[Kory]

Storm surge in Southeast Louisiana is already washing over roads.

 

[Blountwolf]

Pray the forecast track is correct.

 

[Kory]

Pray the forecast track is correct.

I don’t think folks in Southwest LA would do that.

 

[Blountwolf]

I don’t think folks in Southwest LA would do that.

True, but as far as the number of people affected goes - Laura making the turn as expected is very important.

Houston has dodged a bullet. This will not be affecting them directly.

Lake Charles long range radar shows Laura is on a NW heading with maybe some NNW wobbles. This is solidly a SW LA landfall.

 

[Kory]

Storm surge now forecasted to be 18-20 feet! That is in par with Rita which is the storm of record for SW LA. People south of I-10 in Cameron and Vermillion need to get out. Now.
