Dorian @11?

DVORAK estimates at 30 KTS so probably not. It also doesn't look quite as good to me as it did earlier.

Cat  5 into Long Island?

Nah. Re-curves the system towards the benchmark, but I'm sure if that verified there would be plenty of models bringing it into the East Coast leading up to that point, lol. Heavy, heavy hype.

Not quite but if you adjust for it's SE bias and low resolution that's what you get:) Tim Kelley is going to surf with a "I told you" t-shirt.

Tim Kelley said Aug 19th to Sept 25th or something like that, so if by miracle Dorian ever did anything, his forecast busted.

It's fairly rare for a July Cape Verde storm to threaten the East Coast, but we'll see. Note that the NHC only keeps it a minimal TS in the coming days. It's moving into a less favorable environment.

ah yes....and climo says we rarely get effects from those--remember Ernesto a few years ago?  TS warnings everywhere and barely any wind or rain...the media hype after Sandy will be through the roof if anything is within 500 miles of NYC

I posted this in the Dorian thread on the Weather Forecasting and Discussion forum but I figured I would share my thoughts here as well since it is relevant:

 

FWIW the 12Z runs of the Euro and GEM have a tropical wave (which is actually Dorian) just north of Hispaniola at 12Z on the 30th. GFS has Dorian further east more towards Puerto Rico but the fact that the Euro and GEM have picked up on something similar around this same exact time period should warrant some interest, especially given how far out this is. GFS is obviously more progressive with the development but imho I can see the stars aligning within the next couple of model runs given this stays course.

Don't believe a SNE Cat 5 landfall is possible. Cat 4 would even be pushing it, and the storm would have to be accelerating and going over 50 mph at landfall.

The Colonicane in 1635 was likely a category 4, but that's probably the worst possible hit.

SUPERCOMPUTERS UP TO TOMORROW, THURSDAY 7/25.


THE PRODUCTION SUITE ON WCOSS SYSTEM TIDE WILL BEGIN SENDING OUT
THE OFFICIAL OPERATIONAL PRODUCTS AT ROUGHLY 1230Z.
DATA
DISSEMINATION FROM THE CURRENT CCS SUPERCOMPUTER WILL CEASE AT
THAT POINT, ALTHOUGH A FEW MODELS WILL CONTINUE TO COME FROM THE
CCS AS THEY BLEED OFF OVER THE FIRST FEW HOURS AFTER THE SWITCH
TO WCOSS SYSTEM TIDE.
