It's worth noting that 98L has a very large moisture bubble. This should prevent the dry air from hampering steady development until it /briefly/ enters 26C waters in a few days. Until that time, conditions look great for intensification. A low to mid-grade tropical storm seems to be in the table. The long term fate beyond that is unknown.

It's funny how a couple days ago people on here were discussing how water temps. in the Atlantic are very rarely an issue. And here we are in late July discussing about water temps. that are too cool to support a tropical cyclone.

Impressive TRMM pass that shows 98L pretty well organized.

Luis, yeah it is really looking good. I bet NHC ups the development chances for the 8pm EST outlook - possibly to 50%.
Looping the IR rainbow floater shows a rather impressive Cape Verde invest for July!

Good afternoon, Luis... Although unlikely given the current synoptic environment, Puerto Rico and the northern Leewards can be the first targets of non-recurving CV systems during the last week of July and the first week of August. Major landfalls, though unlikely, have occurred with significant loss of life and property. Landmarks are Santa Ana 7/26-27, 1825(930mb?, cat 4,second highest loss of life in PR storm) and Los Angeles 8/2-3, 1837(948mb, cat 3). Better record-keeping would undoubtedly yeild further examples of landfalling majors in the 17th and 18th centuries. Fortunately, it appears that a hostile environment, a product of SAL and subsequent shear between 30 and 55deg W, will prevent 98L from significant intensification east of the islands...Grtz from Key West, Rich

Hail to the GFS!!!!
All those experts that were dismissing the GFS the last couple of days saying that it had convective feedback problems probably do not know what to say now. I could see calling it convective feedback problems in a model's medium to long range forecast but in its short term and from a very reliable model like the GFS is unheard of.
To be fair, the GFS did show two consecutive runs yesterday with nothing but a tropical wave after it showed many runs before that which developed this system. I thought maybe it was about to bust also since it had little model support. We should also give credit to the CMC model which was the only other model showing some development of this invest a couple of days ago. The NAVY and ECMWF models joined late and started to pick up on it last night.
It's hard to i against the GFS, especially in the short-term forecast range.

Re: ATL: INVEST 98L - Discussion
Impressive for any month (let alone July!) to be just coming off the African coast and have great symmetry and have this good convection with banding and now convection blowing up over the center. Here's the last 2 RGB images.

Re: ATL: INVEST 98L - Discussion
Hard to say if it will or wont strengthen after it becomes a TS this far out..

Is the only real problem going to be cooler waters? Or is shear, and dry air going to be a problem too?
Couples days ago some people were saying how water temps are never an issue in the Atlantic when it comes to TC development.

If it moves as fast as Chantal, I can't see 98L surviving.

That has been the problem with multiple storms out in the MDR these past 2 seasons. Makes me question some things about this season.

It looks great this evening. Large moisture envelope with a healthy outflow. Percentages will probably increase in the TWO I am confident about that.
