Hurricane Beryl - Hurricane Warning - Baffin Bay to San Luis Pass Texas


Recommended Posts

Wouldn't it be a hoot if Beryl turned out to be the strongest system of the 2024 season.   You almost want to hope so for U.S. coastal interests.

Hopefully Beryl is not a trend setter for what lies ahead for August, September and October.

 I as a near coastal resident obviously would want that to be the case. But even then a later storm with a 140 mph landfall instead of 150 would of course still be potentially quite devastating/just about as bad. The bar for this season is so high now that not getting another landfall as strong isn't necessarily saying much.

It's too bad hurricane hunters won't be in there till later because I think Beryl is probably peaking now and would love to see data. Have a feeling by time they get there we will be past the peak. Wouldn't be shocked if Beryl is cat 5 now.

Regarding the future track and intensity of Beryl, we have a couple big synoptic players, the SE US ridge and the TUTT extending from the SW Atlantic into the extreme NW Caribbean and west into the GOM. There's a secondary player, a through swinging through the Northern and Central Plains. The ridge and the plains through will mostly dictate the track, while the TUTT, and possible associated ULL, the intensity of Beryl.

It appears this hurricane season the SE Atlantic ridge will be anomalously strong, with throughs swinging through the CONUS at high latitudes, unable to weaken the ridge much, or maybe just dig far south enough to nearly collapse the steering currents while the cyclone is just too far south in the Bay of Campeche.

The TUTT on the other hand is trickier. It's forecasted to pinch off a ULL, but depending on the timing of this, and how far from the TC it sets up, it will either impart shear, or help ventilate the hurricane. The Euro is flip flopping on this, with the 0z and 12z imparting moderate shear, while the 06z sets the ULL farther to the NW, helping ventilate Beryl. So far, most models favor the shear scenario, but there's a caveat. 

I'm usually not a fan of the 'hurricanes create their own environment' saying. Synoptic features like mid latitude ridges and throughs are just huge compared to tropical cyclones, so the effect of a TC is usually negligible. That being said, a big and intense TCs may factor in, specially on borderline scenarios, such as this one, where the timing of a ULL pinching off the TUTT and how far it positions itself from the cyclone.

A stronger, bigger TC, will have a huge outflow, aiding the ULAC expansion, which can assist to pinch off the ULL from the TUTT earlier, and push it a bit to the NW. Beryl is not that big, but it's not the compact storm it was 24 hours ago. 

Anyway, that's some food for thought on Beryl's future.

I feel pretty certain that is a faulty anemometer. FL winds in that area only would support near hurricane force winds.

Yeah I'm not sure about that reading.

I think they meant the Grenada airport located on Carriacou.  I've been following the Sandals resort feeds next to the Maurice Bishop Airport and it doesn't seem like they really had any gusts over 50mph.  The resort staff is currently setting pool chairs and other items back up for use tomorrow.

That must be it then. Thanks for the clarification.

Thanks, everyone. I’ll pull the post down since it’s inaccurate.

This makes much more sense.  No way did the Island of Grenada record a gust that high 30 miles or so south of the center.

I think we have to wait for more information because, as shown in the graphic Chinook posted, the METAR with the 105 kt gust came from TGPY- Maurice Bishop International Airport.

I was referring to the 161mph. Was that the smaller airport over Carriacou?

The graphic in that now deleted post showed the readings coming from the St. George, Grenada area, so that would also be Maurice Bishop International Airport. It's not all adding up at the moment. Even disregarding the 161 mph gust, there's still a huge difference between 50ish mph gusts as the poster claimed was observed from the webcam vs. a 121 mph gust that the NHC itself posted.

I agree, especially since there doesn't seem to be any reporting stations on the small islands that got hit the hardest. FWIW The latest METAR on windy.com says gusts to 67kts 2 hrs ago and 59kts 1 hr ago. Makes way more sense.

It's the 12:00 pm observation that's the question right now. See the post right before yours. BTW, so people don't have to google it, Point Salines International Airport is what Bishop International Airport used to be called.

How seriously should we take the NAVGEM models forecast.. it's outlook for path making landfall in LA has been pretty consistent over the past few runs.. its forecasted lowest pressure is also right at landfall in these runs.

Could it have been the result of an isolated tornado? No funnel cloud noted in the METAR, but visibility was poor.

Maurice Bishop Airport is located on the far SW side of Grenada (Google Earth) FWIW it does have direct somewhat elevated exposure to the W and NW which would put it in a good position to measure higher winds.  In any case it would still be too far away to measure a gust of 121 mph.

NAVGEM has never been a great model for hurricanes. Can’t dismiss it entirely but focus on the major global models and the hurricane models.

I think at this stage it’s good to focus on ensembles for longer range track or looking at the cluster of reliable operational models. NAVGEM is not on that list imo.

I’m particularly a fan of the “super ensemble” that combines the ensembles from major guidance.

It doesn’t mean it’ll be right, as @wxmx and others have pointed out there are still important things to resolve in that medium to longer range, but it’s a really helpful place to start.

18z hurricane models are a bit closer to Jamaica again

IMO, higher than average confidence can be put on being a close call for Jamaica and that it will hit the Yucatan and enter the GOM. The second landfall after the Yucatan and the intensity during any of those landfalls are low confidence now.

I am concerned for wxmx's safety should Beryl strike Mexico. This is an extremely dangerous hurricane.

It cannot be emphasized enough how unbelievable this is. Not much to say except Beryl has defied pretty much all sense of climatology and conventional wisdom. It's going to be a long season. 

The fact it achieved this intensity so rapidly in an environment that wasn’t exactly pristine is all the more impressive. Other canes have had environments more conductive and failed to take advantage of the opportunity. Beryl more than achieved its peak. Really have to credit the high pressure overhead Beryl that aided in ventilation at the perfect time, right when diurnal max was peak.
