I would consider a 40% chance as pretty darn high considering we are talking about the month of May over some pretty cool waters with a ton dry air still around. Anyway this has the makings of a "possible" sub-tropical system at best. Anything more would be very surprising.

Watch this area over the next 24-48 hours:

http://www.ssd.noaa.gov/PS/FIRE/fires-fl-vis-loop.html

Expect some slow development of this system over the next couple of days with a moderate to low 40% chance of becoming Ana at this time. 90L is dead but this one appears it may do more as it is going to stay over the GOM for several days with lower shear and SSTs around 80F. The biggest obstace will be for it to transition from mid-levels to lower-levels and to mix out the cold air aloft to form a vertically stacked, warm-core, again a 40% chance at this time.

I am surprised nobody is here (I predict this board will be crowded again by about 24 hours from now) - 90L is dead but this one is the real one to watch this week (90L was never the real one to watch in the first place). Recall the original thread said "Late this week"...we are tracking to the forecast.

could we see a SubTropical Strom from that low near fort myers/Naples and will it stay near or close enought to the coast that if this would become SubTropical Storm ana that we here in central florida could see tropical storm warnings????????

I'm in the Naples/Ft. Myers area and there is zero wind here. Clouds inland and north of me look very bizarre.

It's more of a snapshot of the atmosphere and what's going on in it.

Those with weekend plans along the N and NW GOM may need to keep an eye out. I noticed the EC and UKMET have shifted a weak low a bit further W into the Upper TX Coast.

Can you take a picture and post it? I'm interested to see what the sky looks like!

Unless the shear decreases dramatically, it stops swallowing dry air, and it sits on the gulf stream for a week, no.

Keep an eye out for rain... IMO that'll be the main feature of this thing regardless of whether it is Tropical, Sub-Tropical or merely just an area of Low Pressure...it's highly unlikely that this will will be a wind maker of any significance

As others have said its doubtful that this system will become too strong even if it does end up becoming a tropical system of some sort, be it sub or tropical in its own right. We shall see!

This system could be a decent enough rainmaker where it does eventually come inland on the gulf, pretty much most of the rain will be on the northern side.

this should extinguish any hopes of seeing ana. it will be a rainmaker at the least.

Cat 5, can you please explain? As I am a novice, what are you seeing? Is it the deep trof in the Gulf?
Thanks!
