In that case, please just kill it now. i'd rather it be stillborn then lead a life of poverty and shame.

Please don't get upset but I have been receiving Hurricane Irene vibes from 94L for some time. Hard to see this going west of New Orleans overall because of the consistent -NAO.

6 days out, a hundred miles or so either way it misses the mountains of Hispaniola.

There are ways through Cuba that don't cross that much terrain.

mildy sacriligeous, but I like to think of the Divine Power has having a sense of humor.

Hey josh! If it is an Irene type I'm sure anyone from the SE subforum up to the SNE will welcome you to chase

:wub: Well, thank you. :)

Yeah, really it's only the E end of Cuba that's mega-bad. The rest is OK, provided the cyclone doesn't stupidly move lengthwise across the entire thing!

It is what it is, hopefully there will be at least one hunk of a low-rider this year; in all it's wonder. Not another Ernesto but something more legit.

:weight_lift:

:wub: Thank you.

Now at 90%

A WELL-DEFINED AREA OF LOW PRESSURE IS LOCATED ABOUT 800 MILES EAST

OF THE LESSER ANTILLES. WHILE SHOWERS AND THUNDERSTORMS REMAIN

SOMEWHAT LIMITED NEAR THE CENTER...ANY SIGNIFICANT INCREASE IN

THUNDERSTORM ACTIVITY COULD RESULT IN THE FORMATION OF A TROPICAL

DEPRESSION TONIGHT OR TOMORROW. THIS SYSTEM HAS A HIGH CHANCE...90

PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS

AS IT MOVES WESTWARD AT 20 TO 25 MPH. TROPICAL STORM WATCHES COULD

SOON BE REQUIRED FOR THE LEEWARD ISLANDS...AND INTERESTS IN THOSE

ISLANDS SHOULD MONITOR THE PROGRESS OF THIS DISTURBANCE.

Think it misses hispaniola to the south. Interaction with cuba might be inevitable unless it shoots the channel. A track wnw across the entire spine of cuba is what scares me the most. If it's a quick north jump it shouldn't take more than a few hours. If it gets entangled for days then its done. Whats most encouraging is the stronger ridging in the longer time period which could bring the central gulf into play.

It is supposed to take the dreaded track between Cuba and Hispanola. it has to 100 miles off that track to encounter less terrain, or somehow sneak it's way inbetween.

Hazel somehow managed tosneak through that area, even that weakened a lot but somehow managed to gain most of it back over the Bahamas.

So as usual, put me down for most pessimistic senario Fay redox.

Edit: Also turn north like Canadian is showing unlikely, but there is still a slight weakness so it could happen.

Ernesto?

You looked at the image URL didn't you. :P Yep. Ernie 2006. Struggled its whole life and just never got organised and in the end, its most lasting legacy was a rain maker for the Carolina,VA,MD & VA. I have no reasoning, it just sticks out in my mind as a kind of "I've seen this movie before" deal.

I actually didn't cause I am on my iPad. Just figured it was one of those crappy storms.

I made a track map for 94L as well as marked the elevation of cuba and hispaniola to show you where 94L would survive better or worse. The red represents higher elevation that would rip apart the outflow channels for a strengthening tropical cyclone. The green markings represented an area where, if passed over, wouldn't be as bad as the red. Weakening is still likely, just not to the extend of if the potential cyclone passed over the red marked areas.

94L is looking slightly healthier than earlier today. Convection seems to be firing up near the center and to the north of the storm which will look much better in the morning if dmax preforms its wonders! I say we have TD8 at 8 am and Issac after the recon passes by the storm. I don't expect the storm to strengthen passed 50 mph all the way to the lesser antilies because of dry air and fast movement. This storm needs to get its mid and low levels stacked to strengthen much and I just don't see that happening until it reaches the E Carr.

Classification can't be far off based on IR. Convection is increasing.

Also, new 00z GFS out to 126 hours has 94L exiting the north eastern coast of Cuba on a NW course. Lets see how it finishes.

Much further east than the previous runs. A trough is coming down from Canada. It might boot this system OTS.

Phil what was the name of the storm that kind of avoided Jamaica due to this phenomenon? I think it was 2008. It avoided Jamaica as if it "knew" it was there. I may be wrong with the year so I apologize, but you may know what I mean.

I have always like that idea and know that when it first was discussed there was a lot of criticism of the concept.
