Great Q, big ten fan!

1. The UK has been found to be a top tier model when looking at average errors over the longterm.

2. I like to post all of the majors, good model or not. But I like to post the UK also for some other reasons like:

-it’s the only one I can find with definitive textual output that’s easy to post without taking up image space and it allows one to post the entire run for a TC on just one page

-so, it’s also good for documentation purposes for when one wants to look back at it for a particular TC or a TC that never formed like the recent Invest 91L

-this complete run’s textual output comes out earlier than all but the Icon of the majors

-The UKMET is often overlooked. You see lots of Icon, GFS, and Euro posts, but hardly any UK despite it overall being a good model. So, I happily fill in that gap.

Great answer 

Thank you so much!

It is a hybrid storm.  61 degrees all day here.  VA Beach had 50 MPH gusts and over 6 inches of rain and it's still going on.  It even had an eye as it was entering the Chesapeake Bay.  It should have had a name.

Think I heard it was a cold core storm, but honestly the radar representation screams a subtropical or weak tropical storm for sure.  

Ocean water temps there NE North Carolina to VA Beach probably low to mid 70's.

It hit tropical status at the last second at impact.

There's no indication it’s tropical. But it’s a hybrid of sorts though hybrid doesn’t necessarily mean subtropical, which is a type of hybrid, either. Most pro mets I’ve seen are saying not ST. I had been wondering if it could be ST.

It def had some subtropical characteristics near “landfall” but I think it fell short. Either way, the NHC wasn’t going to designate that after hesitating on a couple bona fide TCs already this year.

Even though we have two highlighted areas by the NHC, the basin is definitely starting to wake up. 
 

It’s weak right now, but there is a signal on guidance for possible development off the SE coast from a wave or disturbance that ejects out of the Caribbean early next week, and a signal late month for a possible CAG, which better fits climatology than what models were previously showing with a CAG mid-September. There are still headwinds with wavebreaking induced shear, but it seems to me that activity will gradually pick up as TC climo shifts west.  

CAG system late September to early October timeframe would be a very likely scenario.

I keep hearing about comparisons to last year’s slow start to September and while there are similarities with SAL and wave breaking, this one is simply much slower. At this point in September last year we had a cat 2 (landfall in Louisiana) and a TS. We haven’t even had a named storm yet, though that might change by tomorrow. Looking further into seasons comparison, 2024 was WAY more active to this point. Yes system numbers are similar, but at this point last year, we had had 4 hurricanes including a devastating cat 5, a US cat 2 landfall, and a very impactful cat 2 landfall on Bermuda plus Debby, a cat 1 that hit Florida. We have legitimately a 1 storm season this year. Erin was a named storm for 11 days. If you add up the rest of this years systems, you don’t even get 11 days combined from the other 5 systems. Heck 3 of them were only named for a day or less. The inactivity of the entire basin is simply stunning. We are now at 1/2 of our average ACE and that is including a 30+ unit ACE storm! I could go on and on but the point is, this is not like 2024 besides both shared an extended dead period mid season. The difference is 2025 wasn’t active before the dead period. 1 storm does not make the basin “active”. While I am sure future threats will materialize in the gulf and climo favored areas, I am simply shocked by how dead the Atlantic and entire northern hemisphere has been.

The whole hemisphere…that’s really where it gets crazy.

WPAC inactivity is absolutely absurd
