*All available data suggests that Earl has fully undergone extratropical transition. Earl was the second major hurricane of the 2010 Atlantic season reaching Category 4 on the Saffir-Simpson Scale. Unlike Danielle before him, Earl triggered multiple coastal watches and warnings, and now continues as a strong extratropical cyclone. This will be the last SkyWarn UK OT Advisory on Earl.
*Next update: as required - check back regularly for updates.

Satellite shows a pulse of deep convection and what to me looks a clearly defined surface circulation - I leaning toward thinking this is now a tropical depression and would be surprised if it wasn't updated shortly...

Looks like Gaston will be back later today.

The NHC Atlantic Tropical Activity page is looking mighty packed isnt it, Im just glad none of the storms have been close to land or strong storms when they have

It certainly has been an eventful start to September with the Atlantic and Pacific.

Made landfall over Korea yesterday, some fatalities indirectly as a result. Wonder how it will affect the North, as they've been pretty saturated by floods so far this year (by all accounts) 

NHC advisories ceased on the system last night. Convection kind of fell apart! Looks slightly better organised this morning (if I remember correctly as to what they looked like last night!). GFS shows a reasonably powerful storm by the time Gaston makes it to the Leewards area - so perhaps another OT alert barrage!

On a related note, has anyone noticed how E Africa is literally 'shotgunning' lows into the Atlantic? Could be quite an active season after all!

Been thinking about that myself over the past few days. The last five systems have all been Cape Verde types - and the last two hurricanes. Looks like the way they're all flowing off of Africa we could see a few more I think! Average season has about two Cape Verde hurricanes, which we've had and we're only now moving into peak time - I think we're still on for an active season!

Dropped off to a TD, if that! Not going to bother changing the thread title as he'll be back within a couple of days.

GFDL has forgotten about it, but has a tendency toward the same as GFS, HWRF and NOGAP in that he could jog slightly north similar to Earl, possibly sparing the gulf for now.

Was going to say down to Cat3, but he's dropped off to Cat2 with 95kts sustained, maybe due to blowing off his eyewall earlier today. North track has begun, just as suggested by model consensus and enough to avoid any severe damage to the east coast (albeit storm surge doesn't relax as easily as the wind does). Still plenty left to upset the Canadian maritime area though, dependent on how the trough exiting the Great Lakes grabs hold of him.
