Re: Invest 98L Near Bahamas
Maybe when its being carried out to sea it might have a chance. But as of now it has 20 knot shear over it...With only a very broad MLC. But its no were near td3.

With GFDL so strong I would say a depression and then
tropical storm chantal is likely, though I think
it will stay off the coast of the U.S.
Bermuda should watch it.
completely disagree. the gfdl has a history of over intensifying storms. this one hasn't even developed yet. if conditions do become more favorable, then it could develop, but i wouldn't say it is likely.

Shear is 10-20 knots and forecast to decrease north and north-northeast of it, although northeast of it there is an increase expected...

Keep in mind the key at right denotes ACTUAL shear. The dashed and solid lines are tendencies...

Whatever it is or becomes, at least it looks as if S. Fla is not the target, right?

GFDL overintensifies? I didn't know that. Well then I would say possible, not likely.
Interesting...I thought GFDL was pretty accurate....oh well

It is accurate, just sometimes it freaks out. Like with Ioke, it brought it to a 215mph, 850mbar super-hurricane.

Re: Invest 98L Near Bahamas
Looks quite pathetic now as the upper trof has overtaken it. Just a mess of strung out thunderstorms. Absolutely no evidence of an LLC. Not even much of a surface trof. Looks worse than it has for the past day or so. Models are assuming there's a 25-30 kt low to start out with, but that's not the case. That's why they develop it. Now that it's merged with the upper trof, there could be some chance of a surface low forming in a day or so once it moves northeast of Bermuda. But I guarantee it'll not be a TD tomorrow and recon won't be flying tomorrow.
Oh, by the way, that ship reporting the west wind at 5 kts is west of the weak frontal boundary that just caught up to 98L. Just a weak wind shift behind the boundary.

Yep, still could be testing, but with a system that has at least a slim chance of developing in a few days. How about a $50 bet that no recon flies tomorrow?

Nah....I'll pass on that b/c I wouldn't fly unless something drastically changes.

If I remember right, the GFDL had Katrina swinging south just off south Florida and intensifying to, I believe, a Cat 5 before hitting the Keys. Interestingly, the southward swing turned out to be right, just too far east, and it did start strengthening as it was crossing the southwest tip of florida. It just took a while longer to reach Cat 5.

I think you're seeing low clouds streaming north on the east side and mid level clouds associated with the convection to the west streaming south on the west side. Appears to be clouds at different levels moving in opposite directions and not any LLC. It's very hard to identify an LLC on IR imagery. But let's say there was an LLC where you circled. Note the line of convection is to the west and high clouds are blowing the tops off to the east and southeast. Not good.

The GFDL did pretty good with Katrina once it developed. The problem with 98L is that the models are being initialized with a 25-30kt low center that doesn't exist. Bad initialization = a bad intensity forecast.
