Re: ATL: Invest 95L
Wait, this is for the wave off Africa? I thought it was the low in the central Atlantic. Interesting that it's an invest since it hasn't been mentioned in the outlooks at all. Is this an error?

The wave is located around 9N 31W now. I don't think it's an error that it is an Invest, but the numbering may be an error. Expecting an imminent mention in the 8 PM TWO.

Re: ATL: INVEST 95L - Discussion
A vigorous tropical wave is producing a concentrated area of
showers and thunderstorms several hundred miles southwest of the
Cabo Verde Islands. Environmental conditions are forecast to be
somewhat conducive for gradual development of this disturbance over
the next few days while it moves westward to west-northwestward at
15 to 20 mph. By the weekend, however, conditions are expected to
become less favorable for tropical cyclone formation.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...20 percent.

It's in 26-27°C waters right now but has favorable thermodynamics with SHIPS showing 200mb temperatures around -55°C

I think that is because SHIPS assumes a tropical cyclone already exists. SHIPS intensity guidance is very poor for invests.
