We have our first cherry of the 2024 Atlantic Hurricane Season due to a growing signal for tropical genesis in the Bay of Campeche/western Gulf.
This soon to be invest comes from a monsoon gyre/CAG that has been in place over the Caribbean for a while now. With a large area of vorticity/disturbed weather over Central America/Yucatan, a broad low is expected to develop and move toward the coast. It's still unclear how far north the actual center goes, or how quickly something spins up, but the setup for heavy rain over Texas and much of the Gulf Coast is pronounced. As you can see below, life-threatening flash flooding is possible/occurring in Mexico (let's not forget about friends like @wxmx) and Central America.
As for wind, the threat seems relatively low as rain is likely to be the predominant and most widespread impact, but we'll of course have to watch for how any broad low tightens up.
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
1. A large area of disturbed weather is located over Central America,
the Yucatan Peninsula of Mexico, and the adjacent waters of the
northwestern Caribbean Sea. A broad area of low pressure is
forecast to form from this system over the southwestern Gulf of
Mexico on Monday or Tuesday. Environmental conditions appear
conducive for subsequent gradual development of the low, and a
tropical depression or tropical storm could form by midweek while
it moves slowly westward or west-northwestward.
Regardless of development, several days of heavy rainfall are
expected across portions of southern Mexico and Central America, and
these rains are likely to cause life-threatening flooding and flash
flooding. Locally heavy rainfall is also expected to spread over
portions of the northwestern coast of the Gulf of Mexico by the
middle of the week. In addition, gale warnings have been issued
for portions of the Gulf of Mexico, and more information on these
is available in High Seas Forecasts issued by the National Weather
Service.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...high...70 percent.
