Extremely, extremely unlikely, but not impossible.

OT: I am hoping for two snow miracle winters in a row here...



Extremely, extremely unlikely, but not impossible. What, a track like that? or having snow two years in a row? :lol:

Here's one for insomniac researchers: Are there any other seasons that (plausibly) began* with consecutive waves developing. I'll offer 1949 as a possibility.

*Where beginning of season=first tropical storm formation.

I've had the 13 latest starting seasons (post 1944) up in tabs for ages now, that's how I pulled out 1949 without having extensively searched.

3. A LARGE AREA OF SHOWERS AND THUNDERSTORMS NEAR THE COAST OF WESTERN
AFRICA IS ASSOCIATED WITH A VIGOROUS TROPICAL WAVE. SOME SLOW
DEVELOPMENT OF THIS SYSTEM IS POSSIBLE OVER THE NEXT FEW DAYS AS
IT MOVES TO THE WEST AT 10 TO 15 MPH. THERE IS A LOW CHANCE... LESS
THAN 30 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING
THE NEXT 48 HOURS.

For NHC to mention and have a circle on a wave that still has not emerged completly Africa is telling about what they see about development of it.It will be important to see where the low forms to then see how the track will be.

Watch out Cylconeye the 06z GFS and the 0z ECM both don't look great.

The 06z GFS then heads eventually towards the Bahamas and then recurves it just before it reaches Florida.

Seems like there is quite a big amount of uncertainty with this whole set-up, as you'd expect I suppose but small differences makes the difference between a caribbean raker and a recurve with no threat to land.

TWC just showed the GFS showing this storm coming up the east coast. I wonder what hype will result of out that.

Big wave organizing.If I can pinpoint where the low may be forming,it may be around 11N-18W but I may be wrong on that as this system is big and the low may form anywhere.

The convection on the northern end of the wave is already beginning to diminish. If anything forms it will certainly be along the southern end.

It's beginning to start to take on that "look" of organization. I will be interested to see what the wave looks like by day's end.

Yep convection is starting to decrease on the northern part of the wave and looks like we are seeing the first phases of the development of the southern region. If it keeps developing that circulation that seems to be starting to show then we could have an invest in the next 12hrs.

I'm guessing the first storm is our TD while the other is the soon to be "montser". oh wow, if this plays out....well I feel sorry for the islands in the path.
