As others have noted, for lower resolution models there are trade-offs to allow the model to do its thing, not to mention the trade-offs of a global model versus a dedicated hurricane model. I'd wager the folks running it know what they're doing and are making it as accurate for all needs as possible.

I've seen all globals initialize lower than this. Beryl is not an unusually small storm so hopefully we get a review of why this is happening.

Yeah, it's actually identical in size (at least hurricane force winds) to Dorian at peak.

What a strange run, it initializes way too high at 992mb, strengthens in the next 24 hours until weakening upon Jamaica and then regains steam in the Gulf. I'd throw that run in the trash just because the first 24 hours of it make no sense. Maybe something can be gleaned from the track despite the off intensity. It's still sticking with the Northern track.

I am in SE Tx near LA border. When will we have a better idea of what is going on.

I'm just across the border in SW LA and I have the same question -



Hard to tell. for sure after it passes Jamaica. Its along ways away yet.

I would top off preps and check your emergency stuff for the season anyway.

After this clears Jamaica we should have a better idea of where it’s going.

06Z HWRF much further south and weaker in the BOC.
Actual track looks a little south of forecast last few hours but could be part of a longer trochoidal.

A loop in the GOM? That would certainly make things interesting. lol

12z UKMET shifted southward back into northern Mexico. The 0z run was near the TX/MX border.

Isn't the aircraft data input the model? I just looked at the 12z and it initializes at 972. All you have to do is look at the steering currents at various levels to know this will probably throw off the track.
