Remember that these CAG genesis events typically take time and the various models tend to rush things. Also there is a big Western trough that certainly could have an impact later this week on the sensible weather across the Central/Southern Plains. Wind shear could be a problem if genesis is delayed until the coming weekend or early the following week.

I really want to believe. But there is zippo in the W Caribbean or any part of the Caribbean at the moment. What are you guys looking at?

It’s not there yet but is a combo of the Upper trough in the Bahamas and tropical wave in the Mona passage

12z ECM, CMC, and ICON all have a tropical depression or storm moving NW from the Yuc into the GOM in 4-5 days.

Each Euro run seems to be getting a little bit stronger each run. We are just begging for a pattern break along the northern gulf coast, no rain in weeks.

There is lots of unsettled weather north of Hispaniola with an upper level flow that will bring that southwest into the Caribbean. No idea yet if or where to initialize a low. Quite a lot of shear in the Caribbean so its just model runs at the moment.

Well looky here..


North side of that convection is showing bunch of curved inflow.

South side also has clear southerly inflow.

If that convection maintains for the next 12 hours. We could see something trying to get going
