There is some easterly shear,but as the system moves more west,that will ease.

Cycloneye, looks like a threat for Puerto Rico and the islands but we all know the drill. I saw the GFDL but it is only one run.
It's still early to say where it goes and how strong it actually gets.
We have seen many a system where 91L is now pass to the islands to the Northeast...even systems farther south than where 91L is now.
If 91L strengthens more quickly than expected, it should move past the islands to the Northeast.

Re: ATL: INVEST 91L - Models
I'd say that development chances are higher than 30% by Sunday morning. Probably closer to 80-90%. This one looks destined to be a NE Caribbean hurricane threat Monday/Tuesday.

What are the chances that this system makes landfall along the Eastern Seaboard?

It is NOT endorsed by any professional institution including storm2k.org. For Official Information please refer to the NHC and NWS products.
http://www.crownweather.com/?page_id=4557Of much more concern is a fairly well organized tropical disturbance, labeled Invest 91-L by the National Hurricane Center. Invest 91-L was located this morning over the central Atlantic about 1200 miles east-southeast of the Lesser Antilles. Given the overall look of this system and the fact that environmental conditions are fairly conducive to development, I think we will see development into a tropical depression and then a tropical storm by Sunday and Monday. In fact, I will be bold and say that this system could very well become our first hurricane of the 2011 Hurricane Season.
Everyone across the Leeward and northern Windward Islands need to go over their hurricane disaster kits today as this system could be affecting you by Tuesday as a hurricane. Also, if you have family and friends in the Leeward and northern Windward Islands, let them know that they may have a hurricane threat on Tuesday.
After passing the Leeward Islands, it’s tough to say where it will go given that it is up to 5 to 7 days away, however, this system has the potential to be a threat to Puerto Rico, Hispaniola and the Bahamas.
This is a system that I will be monitoring throughout this weekend and into next week and I will keep you all updated.
That's a bit worrying


Let's continue to monitor closely the situation.

my friends in the Carib. I noticed the term Hurricane, probability seems high to deal with a cat 1?!
Let's continue to monitor closely the situation.
If these models come to pass you guys will be dealing with more then a cat. 1 Hurricane. SHIPS was forecasting a 107kt cat. 3 by 120 hours, GFDL is showing a 105kt Cat. 3 by 126 hours. If I were you I would start preparing now for a cat. 3/4 early next week. Better to be safe then sorry!

Re: ATL: INVEST 91L - Models
Is my memory correct? I recall HWRF was on the money last year in forecasting the track of Tomas. If so, here's hoping it is true again this year.

To early to tell at this point. First area to be concerned about is the Islands. After that there will be time to worry about a possible US landfall where ever that may be. Appears at this point though that the Bermuda High will shift east allowing 91L to recurve out to sea with out making a Main land US landfall. We shall see though. Still plenty of time for us to track 91L!

Waouw Cycloneye, that does not sound good if this trend continues. Something to keep an eye.
Especially if you see what GFDL has at the models thread.I already started preparations in anticipation of the last minute rush.
