NHC is quite strict with this system.

Re: ATL: INVEST 97L - Discussion
It's amazing how close we came to having two storms classified today. Make 98L a little less frontal and give 97L a completely unambiguous surface spin and they'd have little choice to upgrade 'em despite how strict they are with probs this year. Not that I can blame them too much given the hostile environments both storms are faced with; usually don't seem too keen on upgrading stuff that would only have hours to live at most which I guess is fair enough.

Colors of lost purpose on the canvas of irrelevance
Not a meteorologist, in fact more of an idiot than anything. You should probably check with the NHC or a local NWS office for official information.

Re: ATL: INVEST 97L - Discussion
Heading into some serious shear now. It has to contend with dry air too. That's a lethal mix. This probably won't develop at all. But we'll see.

Naked LLC this morning, perhaps yesterday afternoon it classified as a weak TD before loosing all the convection during the night.

Like a copperhead snake on your porch...not unhappy to see the "head" chopped off this system. After Florence, still have not been able to get back to Wilmington, I welcome the dry air and shear!

Re: ATL: INVEST 97L - Discussion
2 PM TWO:
A weak low pressure area located about 500 miles east of the
Windward Islands is producing disorganized showers and
thunderstorms to the east of the center. Strong upper-level winds
and dry air should prevent significant development of this system
while it moves west-northwestward at around 10 mph.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.

If 97L would have had model support for development or closer to the US it would had been upgraded to a TD shortly.

Convection fires back over the center and it certainly deserves to be upgraded.

Agree! I think the recent convective burst near the center merits this to be desigmated as a TD.

NEVER, EVER SAY NEVER in the tropics and weather in general, and most importantly, with life itself!!

Re: ATL: INVEST 97L - Discussion
4:20 PM EDT Update from NHC:
Shower and thunderstorm activity associated with a
well-defined low pressure system located about 500 miles east of the
Windward Islands has become better organized over the past few
hours, and a tropical depression could form later tonight or
Saturday. Strong upper-level winds and dry air are likely to
prevent additional development of this system by late this weekend
while it moves west-northwestward to northwestward at around 10 mph.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...40 percent.

Re: ATL: INVEST 97L - Discussion
Reminds me of Henri in 2009. A disturbance that started facing strong wind shear but developed a strong convective burst near the center to get upgraded.

Some might beg to differ. I can think of a hilarious meme of a cat secretly wanting a storm to get bigger and bigger. But I won't share it here, because its text contains an f-bomb.

Re: ATL: INVEST 97L - Discussion
Depression could form tonight.
A well-defined low pressure system located about 400 miles east of
the Windward Islands has produced persistent thunderstorms just east
of its center for the past several hours. If current trends
continue, advisories could be issued on a tropical depression later
tonight or on Saturday. By late this weekend, strong upper-level
winds and dry air are likely to prevent further development of this
system while it moves west-northwestward to northwestward at
around 10 mph.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...medium...60 percent.

I'm guessing this may be the reason for the upgrade.
