Or, the wave currently in Africa quickly develops, and 98L ends up being named Julia

Re: ATL: INVEST 99L - Discussion
Looking for the odds to be bumped substantially later today. This wave is looking very healthy. Interested to see ASCAT if we get a good pass.

ASCAT did make a pass, but the convection is sheared to the west

All observations are in Tecumseh, OK unless otherwise noted.
Winter posts are focused mainly for Oklahoma & Texas.
Take any of my forecasts with a grain of salt, refer to the NWS, SPC, and NHC for official information
Never say Never with weather! Because ANYTHING is possible!

Ah, thanks for the info. I must’ve missed it earlier.

Jeez it’s hard to keep track of everything out there. A week ago today it seemed like this’ll be a below average, slow-burn season. Now we have three AOIs competing for the next name on the list alongside a TS and a Cat 4 hurricane.
The first SHIPS output shows a very favorable environment…except for the fact that RH values are only in the 50s%. This might be a sleeper and over-achiever if it can avoid taking in too much dry air, which will be very difficult for it.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

3. East Central Tropical Atlantic:
Shower and thunderstorm activity has continued in association with a
tropical wave located several hundred miles west-southwest of the
Cabo Verde Islands. Despite a dry environment, slow development of
this system is possible over the next several days as it moves
northwestward and then westward over the tropical Atlantic.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...30 percent.

Re: ATL: INVEST 99L - Discussion
Finally being analyzed by TAFB...
...TROPICAL WAVES...
A central Atlantic tropical wave is near 32W from west of the Cabo
Verde Islands at 16N southward through a weak 1012 mb low at
10.5N32.5W, and moving west at 5 to 10 kt. Scattered moderate to
isolated strong convection is present from 09N to 14N between 30W
and 36W. Slow development is possible and there is a low chance of
formation for the next 5 days.

Doesn't have much support from the models but I could see this becoming a TS

A broad area of low pressure located several hundred miles
west-southwest of the Cabo Verde Islands continues to produce
disorganized showers and thunderstorms. Despite a dry environment,
slow development of this system is possible over the next several
days as it moves slowly northwestward or northward over the
tropical Atlantic.
* Formation chance through 48 hours...low...20 percent.

In addition to the convective bursts getting better organized in the past hour or so, it looks like the broad low-level rotation is also being pulled closer to the convection (it was well to the SE in the afternoon).
