Yup. Lisa will hopefully be a Julia and just add ACE. Matthew...well he may be a trouble maker...I know 94L isnt a large concern and Igor is the main focus but a 80% system with 4 pages?
------
AN AREA OF LOW PRESSURE IS LOCATED ABOUT 375 MILES WEST OF THE CAPE
VERDE ISLANDS. SHOWERS AND THUNDERSTORMS HAVE CHANGED LITTLE IN
ORGANIZATION DURING THE PAST FEW HOURS...BUT THE CIRCULATION
ASSOCIATED WITH THE LOW APPEARS TO BE IMPROVING. ENVIRONMENTAL
CONDITIONS ARE CONDUCIVE FOR A TROPICAL DEPRESSION TO FORM LATER
TODAY OR ON MONDAY AS THIS SYSTEM MOVES SLOWLY NORTHWESTWARD AT
ABOUT 5 MPH. THERE IS A HIGH CHANCE...80 PERCENT...OF THIS SYSTEM
BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.

18z Best Track

No upgrade yet but that could change.

No reason why this should not be TD right now. I would think they would upgrade today at some point.

Note: If I make a post that is brief. Please refer back to previous posts for the analysis or reasoning. I do not re-write/qoute what my initial post said each time.
If there is nothing before... then just ask

I believe the sky is falling...

I agree. Plenty of convection, a circulation...at least 25kts. We still got another hour so they may upgrade it.

I don't know what visible satellite views y'all have been observing ...but the limited ones I have available for that area are not definitive enough for me.
Based on the IR Sat shots I doubt this one is ready for TD status yet.

It has a nice circulation and enough convection to be upgraded, but I wouldn't be surprised to see the NHC wait a little longer.

Re: ATL: INVEST 94L - Discussion
I am expecting it early tomorrow morning. No reason to right now being so far out and the NHC rarely upgrades things overnight.

Re: ATL: INVEST 94L - Discussion
Circulation is a little elongated and weak at the surface in my opinion. Very well defined mid-upper level circulation however.

Its pretty close to being a TD right now, which is obviously why the NHC have upped it to 80% now...but I agree probably going to wait just a smidge longer, no rush given its not going to be a threat to any land.
