We have a new disturbance that has rapidly formed, and is still improving, in the southwest Gulf of Mexico.
This feature deserves to be watched closely. At present, conditions are not especially unfavorable for some further development, and steering currents would suggest a continued motion generally to the northwest.
This is indeed a time of year when tropical cyclones are climatologically favored to form in the Gulf of Mexico and make landfall, somewhere, and very often along the United States, so this does not come as a complete surprise.
Real-Time Image (time sensitive)
In the lower left of this image is Tropical Storm/Hurricane Andres, along western Mexico. The feature we are considering, for a likely impact of some kind, one way or another, along southern US and/or eastern Mexico states, is the trough of low pressure in the southwestern Gulf of Mexico.
This area of disturbed weather appears to have two spots of slightly increased cyclonic flow at the surface, with the currently more dominant one located near 21N 96W - and closer to a mid-level circulation fairly obvious in the daylight visible image of present - and a small secondary region of currently milder surface spin, down around 19N 94W.
Given its close proximity to land and relatively close proximity to east Pac Andres, it may have a limited window in which to become a bona fide tropical cyclone within the next few days, provided enough of it remains over water.
