Hurricane Earl Western Atlantic

[sleetstorm]

The northeast Leeward Islands are being pummeled with very heavy rain and wind this morning.

Steve, I have family on Nantucket Island right now, and while we've been through a few storms out there in the past (Gloria, Bob, No Name, etc.), we've never encountered a Cat 3 storm. Do you see Earl maintaining Cat3 intensity for the next 3-4 days, or do you think he might back down when he hits the colder water of the NE coast?

I think it could easily be a Cat 2 when it passes Nantucket. Fair chance of low-end Category 1 hurricane winds. Strongest winds will be east of the track.

What a beauty. Too bad the islands have to deal with this. One of the best looking hurricanes that I have seen in a good while. We need to keep track of this storm especially during the turn to the NE. That will be a big key to how fast and sharp of a turn it is. That could save or destroy the east coast.

Looks like a eyewall replacement cycle (ERC) may occur. Could be some nice images if that happens. It is an amazing cyclone and just enough offshore, so far.

Yes here is what wxman posted:

As of 5PM CDT, the SEF/ERC probability model is now estimating an 82% chance of at least one event in the next 12 hours, and a 100% chance in the next 36 hours. The model suggests the potential for repeated ERCs in the next 2 days.

So I wouldn't joke too much about noticing an ERC in progress. It is in progress.

Doesnt quiet say clear to me yet

[Ptarmigan]

Quite an impressive storm. I think Earl could be a Category 5, a first since Felix in 2007. Prayers to our friends in the Virgin Islands getting whacked by Earl.

[sleetstorm]

Is there any way to tell how much lightning is being generated by that hurricane like there is for continental thunderstorms?

The last time that I saw Hurricane Earl, its southern most bands stretcheded nearly as far south as the Venezuela coast.
