A Tale of Two Invests

Good morning, everybody, Dr. Rob Carver filling in for Jeff on Independence Day.

Currently, NHC is monitoring two different areas for possible tropical cyclone development. Invest 95L is about 125 miles west-southwest of the mouth of the Mississippi and it doesn't have much thunderstorm activity associated with it. Dry air from the north and strong wind shear have weakened it considerably from yesterday, and NHC believes it has a 10% chance of becoming a tropical cyclone before the feature makes landfall.

Invest 96L is in the western Caribbean sea and bears watching closely. Earlier in the morning, the convection was all on the east side of the circulation center, but thunderstorms have developed on the southwest side. According to the CIMMS wind shear analysis, 96L is on the outskirts of a low wind shear region just east of the Yucatan peninsula. It's also over warm SST's (>29 deg C), so it could intensify. NHC gives it a 20% chance of becoming a tropical cyclone in the next 48 hours. Computer models have 96L going through the Yucatan Channel then turning left and making landfall somewhere near the Rio Grande.

Next Update
My next post will be sometime Monday afternoon/evening. If the situation changes significantly before then, I'll make a new post. In any event, enjoy the holidays...

So Miami you are saying that the Fat Lady is warming up and about to sing to 95L


95L's circulation will be coming onshore within the next hour or so, and no development will take place in that period of time.

4198. Moving pretty fast in that last radar loop - high top must have caught a faster, southerly flow and decided to scoot on towards shore.

wow,TPC has a new word for the model runs..."contaminated"...bets on this being a contaminated season??
Contaminated with Spurious Convective Feedback? Sure, it is built-in so count on it, plus plenty of the seriously unspurious convection.

I'll be getting into my Hurricane/Depression suit and Going Live with the 95L Landfall here this evening.



Your obviously getting a strong onshore Wind...much oil coming onshore that you know of.

If 96L gets it act together before moving into the GOM we will have a MAJOR HURRICANE COMING!

And i believe 95L is at least a TD now.....at least so......





so confusing. It is going to form, it isn't going to form....it will go here. No, it will go there......aaawwwww......if only we had a crystal ball to see where the storms would go and how strong they will be.

Doesn't matter much, 95L is making landfall now as we speak

but it was never a TD because that front was always attached

It does appear that 95L may not be attached to the front now, but it is too late IMO

the system does not have enough organized convection and will not have enough time

If 95L had done this 2 days ago, no question it would have gotten a name


Guess I'm not crazy then? lol

Uh...might wanna go back and check your history. At that point in time he was a minimal tropical storm and on a downward trend.


exactly.. 55mph tropical storm at that moment in time

Lol, COC is an abbreviation for Center of Circulation...and he is improving, but I just can't see the COC, maybe I'm blind? lol

4165. TS, yeah, the HPC even had an "H" slapped over it last evening. It just needed a little more time over open water - a little too close to land and the dry air to contend. Still, quite impressive for a tiny system this close to shore. It's been interesting to watch.

oh ok. I don't see that, but it looks like it is building more convection....so I think anyways...

LOL. I can't believe that 95L actually said this on twitter:

"Latest visible satellite imagery and wind observations south of LA suggest invest95L is getting better organized and could be forming a TD."

No wonder he works at the weather channel.

Actully it appears 96L is really trying to pull things together now.......lets see if it continues....

Albit......FRont attached or not.....and i really don't see it attached now.....95L is a nice spinner...and does not look nor have the appearance of anything but, Tropical now...IMO!
If anything it is now attached to a WARM FRONG not a COLD FRont now......


I'd kinda like to be attached to a warm frong right now. I think it would feel good

I guess then 95L will go down as the little invest that couldn't. You can tell the poor little guy just wanted a name ...
