The disturbance in the NW Caribbean has gotten much better organized and is now Invest 95L'

A broad area of low pressure located near Grand Cayman Island is
producing a large area of showers and thunderstorms mainly east and
south of the center. This system has become much better organized
since yesterday, and a tropical depression could form during the
next couple of days while the low moves slowly toward the northwest.
This system is now anticipated to move near western Cuba this
weekend and move slowly across the southeastern Gulf of Mexico by
early next week. Regardless of development, locally heavy rainfall
will be possible over portions of the Cayman Islands, Cuba,
southern Florida and the Keys, and the northwestern Bahamas through
the weekend.

* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...60 percent.

Definitely keep a close eye on it...from the panhandle through the entire Florida peninsula. This is the time of year that storms like to bend north and northeast thanks to approaching cool fronts. We've also seen some pretty significant storms in the past take a track similar to what 95L may take.

Well, only fitting for this year, tracking a potential Gulf disturbance when we're almost to Halloween. LOL.

Going to be interesting with regards to this system's future. Based on satellite presence, I would expect the percentages for development to increase later today..

Forecast models have been trending stronger with the ridge of high pressure to the north of this system, which favors a track of the disturbance into the southern Gulf of Mexico by Tuesday.

Key longer term looks to be the system's strength & the timing/strength of the approaching cold front mid/late week...

Stronger system & stronger/quicker-arriving front -- Not a problem for Louisiana as it will be steered well east of our area.

Weaker system & slower/weaker front -- System may find itself further west towards the Central Gulf Coast.

Fortunately, wind shear does look to be an inhibitor once in the Gulf, especially the northern Gulf by Wednesday/Thursday. In addition, cooler water temps in the upper 70s in the northern Gulf of Mexico.

Can this season end already...

From Zack's FB a moment ago...

Invest 95L is now in the red.

Satellite images and radar data indicate that the broad area of low
pressure located just west of Grand Cayman Island is gradually
becoming better defined. Environmental conditions appear conducive
for further development, and a tropical depression will likely form
during the next day or two while the low drifts toward the
northwest. The system could move near western Cuba by Sunday and
move slowly across the southeastern Gulf of Mexico by early next
week. Interests in western Cuba, the Florida Keys, and southern
Florida should monitor the progress of this disturbance. Regardless
of development, locally heavy rainfall will be possible over
portions of the Cayman Islands, Jamaica, Cuba, southern Florida,
the Florida Keys, and the northwestern Bahamas through the weekend.

* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...70 percent.

Stay tuned is what I would say.

EURO doesn't do anything with it as far as I can tell.

Invest 95L is getting close.

Satellite and surface observations indicate that a broad area of low
pressure has redeveloped just south of Grand Cayman Island. Shower
and thunderstorm activity continues to increase in organization,
and environmental conditions are expected to remain conducive for
further development. A tropical depression will likely form during
the next day or two while the low drifts toward the northwest or
north. The system could move near western Cuba by Sunday and move
slowly across the southeastern Gulf of Mexico by early next week.
Interests in western Cuba, the Florida Keys, and southern Florida
should monitor the progress of this disturbance. Regardless of
development, locally heavy rainfall will be possible over portions
of the Cayman Islands, Jamaica, Cuba, southern Florida, the Florida
Keys, and the northwestern Bahamas through the weekend and into
early next week.

* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...90 percent.

stormydds: Thanks for your response. I felt that is the case. that's too bad. Has there been any peer reviewed papers on the LRC hypothesis? Nov 4, 2022 14:01:51 GMT -6

Zack Fradella: Not sure, the LRC is something that takes a lot of work to follow and keep up with. It's not as easy as looking at the parameters and making a forecast. This deters many from even giving it a chance. Also, there is some doubt from the weather world. Nov 4, 2022 3:38:49 GMT -6

stormydds: Zack, a friend had a meeting in Lafayette which Rob Perillo spoke.He asked him why the LRC is not used to forecast hurricanes by NOAA.His answer was that Lezak won't share the info.I saw the podcast you and David made with Gary.He seemed open.What gives? Nov 3, 2022 14:39:19 GMT -6
