Re: NW Carib Flare-Up
From srain: The 12Z ECMWF has a very sharp trough attempting to close off a surface low as it approaches the Middle TX Coast Sunday morning near Matagorda Bay. This run of the Euro is the sharpest trough I've seen all week via the ECMWF.

Re: NW Carib Flare-Up

Models have trended just the opposite - away from SE TX and LA with the heavier precip. 12z Euro has most of the precip moving into NE Mexico. GFS still has some heavy rain on the mid Texas coast, but not much from Houston eastward.

Too soon to say. The best forecast would still be 2-5 and 6+ isolated.
Invest 92l will probably be up soon.

WPC 15Z analysis depicts pressures around 1012 mb near the surface trough in the Northwest Caribbean.

NEVER, EVER SAY NEVER in the tropics and weather in general, and most importantly, with life itself!!

Re: NW Carib Flare-Up
To be clear, this is a different system than 91L?

Re: NW Carib Flare-Up
Any 12z EPS support? Also if anyone has a free method of checking without clicking through every ensemble member on weather.us that would be greatly appreciated .

Re: NW Carib Flare-Up
With this kind of setup, qpf forecast can change drastically quickly for any given area, depending on if the system wraps up or not. If it does most of the rain would be shifted to the north and east of the center of circulation and a stronger system would be able to concentrate rains better over an area, which would probably give Southeast Texas the heaviest rain, while an open wave could have a harder time fighting off the High pressure to our east, hence why the models that show an open wave shunts the moisture plume further to our south quicker. While the models that show more of a closed low like the CMC produces a much higher amount of qpf across the area. Bears watch imo...

Re: NW Carib Flare-Up
There's a trend of persistent convection over the northwest Caribbean so far this season. With the MDR so cool the western Caribbean, Gulf and areas off the southeast coast will likely be the hot spots with close in development...maybe fewer systems overall but short fused threats that can escalate quickly...especially once we hit the mid August and beyond hot zone..

Re: NW Carib Flare-Up
Way back when, at the time that the GFS in particular began to give us model runs depicting formation coming out of the W Carib and into the GOM, we waited and from the monsoonal gyre interacting with a tropical wave we got 91l. I don't watch models near as closely as many on this site, but is it possible that the system we see now in the NW Carib might have been what the GFS (and a few other models) was hinting at for development in the GOM. Perhaps its academic, because from what I hear from many of you, the only model giving any real support for this feature right now is the CMC.

There seems to be quite a bit of support for a system in the gulf by the EPS but I'm not sure if that's the same system which is being discussed in this thread. In fact, some of the members are even showing hurricanes. Here are some useful EPS links:
Wind speed values for all individual EPS members:

MSLP values for all EPS members:
