It also states:
"THIS DISTURBANCE IS SHOWING SIGNS OF ORGANIZATION...AND ENVIRONMENTAL CONDITIONS ARE CONDUCIVE FOR GRADUAL DEVELOPMENT OVER THE NEXT FEW DAYS."

If it comes up the Carolina coast as a Tropical Depression and drops 10 to 15 inches of rain we won’t complain.

30% is low risk of formation.

But this system bears watching as it has a long way to go...

Could that graphic be any cruder? It’s 2011, not 1972.

It is the standard Mariners' 1-2-3 Rule chart as produced by NOAA. You will get prettier graphics from NOAA when this system becomes a numbered Tropical Depression or a named Tropical Storm or Hurricane,

Agreed, although National Hurricane Center calls 30 to 50 percent a medium chance. Note however that this is a 48 hour chance and the chance will be updated as time progresses.

Note that this system has about 2000 kilometers to go before it crosses the Lesser Antilles.

Long way to go to get to the east coast but given its relatively favorable for development enviornment, I don’t think anyone wants to have a visit by this storm in ten or so days. Looking at the sat images this AM, it looks like it will become a named storm within 48 hours. Some are calling for it to be a hurricane by tuesday next week.

Better graphic but not showing the potential cyclone formation in the mid Atlantic that is the subject matter of this thread.

The above is more my point. It is very early for this storm, and I am not sure how warm the waters are where it currently is.

That does not mean that this thread is not fruitful. On the contrary, people can start following this potential storm system. And most weather broadcasters pay attention to this area of the ocean for potential storm systems.

If the storm would be entering the Gulf of Mexico with its sizzling waters, I would be concerned about rapid intensification.

With this potential storm, different countries will have some time to prepare...

That is a good thing...

The National Hurricane Center (NOAA) has finally assigned a satellite for this system:

Atlantic Floater 2 Assigned to 91L

Atlantic Floater 1 is currently assigned to Tropical Storm Don...

They may not have assigned a satellite before now to same on repositioning of satellites -- which might expend fuel and affect the life of the satellite.
