always so cool you can see 1-minute high resolution updates if the GOES-EAST is doing the mesoscale sector like this

998mb with a closed eye per the VDM. Can’t say I recall a system this messy with such a high pressure having a closed eye.

Would you be surprised if this fails to get major status

It’ll get there. It’s organizing, it’s just not pretty. The environment is favorable and if a closed eyewall holds it’ll intensify today and probably take off this weekend. 

[hawkeye_wx]

The latest recon pass found the wind north of the center is up to 72 kts at flight level.  The shear has abated and convection is attempting to wrap around the center.  It should become a hurricane this afternoon.

are people overhyping sinking and dry air?

Copied from another BB: 998 mb is a pretty high SLP for a hurricane but there’s a rather strong sfc high to its north adding to the gradient:

Staff are working remotely in Ibiza and Napa then 

anyway BT has Erin at hurricane strength 

[NJwx85]

Another shift West with the 12z spaghetti models. They all now make it to at least 70 W before recurving. The vort that eventually kicks this out should be onshore tomorrow so hopefully the we’ll get a better consensus by Sunday.

I was just about to post the same thing. LOL.

TS watches are up for the northernmost Leeward Islands.
Looks like there is still some dry air being entrained in, which is probably why Erin is not intensifying faster.

[WxWatcher007]

Forecast to be 120kt in 72 hours, so this should take off once it can shake off possible dry air entrainment. 

Hurricane Erin Discussion Number  17
NWS National Hurricane Center Miami FL       AL052025
1100 AM AST Fri Aug 15 2025
 
Erin has become better organized during the past several hours. The 
last few NOAA and Air Force Reserve aircraft passes through the 
cyclone have indicated the formation of an eyewall, with the Air 
Force Reserve aircraft reporting 700-mb flight-level winds of 75 kt 
northeast of the center. In addition, conventional satellite imagery 
shows the development of a central dense overcast, and a recently 
received WSFM microwave overpass shows a well-defined ring of 
shallow to moderate convection in the 37 GHz imagery.  Based on 
these data, the initial intensity is increased to 65 kt and Erin 
becomes the first hurricane of the 2025 Atlantic Hurricane Season.

The initial motion is 290/15. The subtropical ridge to the north 
will continue to steer Erin west-northwestward into the weekend. 
Encroaching mid-latitude westerly flow is forecast to cause a 
weakness to develop in the ridge during the latter part of the 
forecast period, and this will result in the hurricane gradually 
turning northwestward and northward by 120 h. The guidance remains 
in fairly good agreement through about 60-72 hours. After that time, 
there are some differences in both the forward speed and cross-track 
spread with the turn toward the north. The regional hurricane models 
again lie along the western edge of the guidance envelope, while the 
GFS and Google DeepMind models remain on the eastern edge. Although 
still spread, the guidance envelope has not shifted significantly 
since the last advisory, and the new track forecast is an update of 
the previous forecast. There is still uncertainty about what impacts 
Erin may bring to portions of the Bahamas, the east coast of the 
United States, and Bermuda in the long range.

Erin is currently in a favorable environment for strengthening, 
although there are some uncertainties on whether dry air is 
entraining into the core. The improved low-level structure 
indicates potential for rapid strengthening, and based on this the 
first 36-48 h of the new intensity forecast shows a faster 
development rate.  After 48 h, the hurricane is forecast to 
encounter some northerly to northwesterly vertical shear that should 
at least slow development. However, the global and regional 
hurricane models are in good agreement that Erin will become a 
powerful and increasingly large hurricane over the southwestern 
Atlantic over the weekend and into next week. It should be noted 
that the the Florida State SuperEnsemble and the US Navy COAMPS-TC 
models forecast higher peak intensities than the official forecast, 
so it would not be too surprising if Erin became stronger than 
currently forecast.
 
KEY MESSAGES:
 
1. Heavy rainfall tonight through Sunday across the northern Leeward 
Islands, the Virgin Islands, and Puerto Rico may lead to isolated 
and locally considerable flash and urban flooding, along with 
landslides or mudslides.
 
2. Tropical storm conditions are possible for portions of the 
northern Leeward Islands, where Tropical Storm Watches are in 
effect, beginning on Saturday as the core of Erin passes north of 
those islands.  Gusts to tropical storm force are possible in 
rainbands over portions of the Virgin Islands and Puerto Rico later 
in the weekend.
 
3. While the threat of direct impacts in the Bahamas and along the 
east coast of the United States appears to be gradually decreasing, 
there will still be a significant risk of dangerous surf and rip 
currents along western Atlantic beaches next week.

4.  Interests in Bermuda should continue to monitor the progress of 
Erin since there is still a risk of strong winds, heavy rainfall, 
and high surf by the middle part of next week.
