I dont see this going north of the islands. the ridging should build in quite strong behind katia. it could come quite close to PR and Hispaniola however. Thats my present thinking.


As I'm sure you know but in case others don't, it's a new ballgame starting ~9/15 if the latest runs of the Euro/GFS are close to being correct with strong hints of persistent US east coast/NW ATL ridging getting established then, the likes of which really have yet to be seen this summer. The fact that we're in a La Nina makes this all the more believable. Just because ridging there has been pretty rare this summer does by no means mean it won't occur in a persistent nature this time. More ofthen than not, especially in a La Nina, this occurs at least a couple of times a hurricane season. This is especially the case when a strong surface high comes down from Canada as the models are saying is likely to occur next week.




Agree and the 0z EURO showed this as well....also might add the BOC area gets buries into MX in the 0z as well.....

also will add it doesnt look like a TD to me.....really broad area with an elongated low level cyclonic turning....still has some ways to go IMO...I think it will get there though...

Yea, with Fall right around the corner, and Fronts/Troughs in abundance, any CV storm will likely recurve, although there's always an extremely slim chance that does not happen. For anything to effect the USA now it will pretty much have to originate in the Carib or Gulf.

Once we get the ECMWF to show a recurve, game over - meaning there is a good possibility it may indeed even miss the islands.

We shall see on the 12Z.

As for track with this system. the models are way to fast with motion. We should see a shift south with future runs once we get a NHC position for the models to initialize with and speed.

Aric,there you go!!

90%

SATELLITE IMAGES INDICATE THAT A TROPICAL DEPRESSION COULD BE
FORMING ABOUT 725 MILES WEST-SOUTHWEST OF THE CAPE VERDE ISLANDS...
AND IF THIS TREND CONTINUES...ADVISORIES WILL BE INITIATED LATER
TODAY. THIS SYSTEM IS EXPECTED TO MOVE TOWARD THE WEST OR
WEST-NORTHWEST AT ABOUT 15 MPH AND HAS A HIGH CHANCE...90
PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.
