0Z UKMET mostly missing PR but landfalls into DR and then recurves out

[NDG]

Fort those wondering about last night's UKMET's run, its 06z through 60 hrs was a little further east.

[Hypercane_Kyle]

IMHO, all of the models are way too strong over the next 24 hours. Whether-or-not this has a meaningful impact on track between now and then remains to be seen.

Its 06z run showed it making landfall in SW PR, its previous 0z was maybe 5 miles offshore.

The stronger she gets the quicker she turns

[NDG]

12z GFS is still persistent in Fiona becoming a hurricane just prior to making landfall over PR but definitely not as aggressive as its previous 06z run after the correction placed on it at 12z of its much weaker state.

I disagree, it looks much better than yesterday, its in a much better environment (more moist, less shear) if it can stack then IMO RI seems pretty likely. Not to mention the NHC seems to disagree with your statement.

Fiona's put in some work over the last few hours for sure, but the GFS has this basically a hurricane by sunset. I don't think we're there yet.

I agree, depends if it can get its act together, Sometimes they do, sometimes for whatever reason, they never do. Id lean towards west of the GFS though

Can someone post the latest UKMET model please. Thanks

12Z UKMET goes NW over far E PR (E of SJ) and then moves WNW for short time followed by NW...so quite a shift E from prior run at PR!

12Z UKMET

[tolakram]

12Z GFS

[ChrisH-UK]

A couple of close in high res models of Fiona as it approaches Puerto Rico, NAM has 100 mph and GFS has 90 mph winds.

[NDG]

Hurricane or no Hurricane the bigger story for PR will be the excessive amounts of rain that the models show, especially if it tracks over the SW tip of the island like the latest 12z Euro shows, not so much if it tracks more to the right like the GFS shows.

[tolakram]

12z Euro (fast)

[tolakram]

Full Euro through 120. What are the odds of another storm sneaking through the passage?

[tolakram]

Euro precip estimates

[Spacecoast]

12z Euro ensembles... ~ 6-7 weaker members (12-14%) drift westward after going over central DR...

[AtlanticWind]

Euro still has some ensembles going pretty far west, Gfs has none.

[KirbyDude25]

12Z HMON blows this up into a 925mb/120kt monster in 5 days, with the eastern half scraping Bermuda. A lot of these show significant deepening, but even those keep it around 940-950, not sub-930
