Low Pressure east of Windward Islands (Is Invest 94L)

An incipient area of convection is just off the West Coast of Africa but it has not been introduced as a Tropical Wave. The models dont do anything with this at this time.

It was introduced in the 12z Surface Analysis:

Updated and zoomed-out visible imagery shows a mid level circulation centered near 12N 19W.
But it may just be a mid level one.

It is impressive. Looks like too much subsidence for development.

Most of the EC ensembles, along with the operational run, show a tropical storm forming within the next few days and tracking generally WNW at high latitude.

Convection has increased in the past few hours but it not may mean anything but otherwise it might be something so we wait and watch.

The 0zEuro seems to develop this in 2 days into a tropical cyclone, I don’t know about that but this may need to be monitored for possible spin up the next few days

If the Euro is the one model that successfully predicts development and all the other globals fail…wow, what a comeback from last year.

My hat is set aside in the event the Euro is right.

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.

Watch the Euro drop development of this, and then it develops in about 3-5 days.

I guarantee the 12z Euro will drop it.

If the Euro actually verifies and we get a designated TC near the Cabo Verde islands within 48 or 72 hours...that would be quite a comeback

I am waiting for the TWD to see if this thread will have to be split.

It's a bit confusing as to if it's associated with this wave or if they repositioned the low I posted about. It seems a fair amount of repositioning has been done lately.
