Disturbance in NW Gulf of Mexico designated Invest 90L; watching two other areas

Author: Meteorologist Dylan Federico
Published: Updated:

Invest 90L in the NW Gulf of Mexico, is unlikely to become a depression before pushing into Texas Monday night. Depression or not, impacts will be the same, with much-needed rainfall tonight for upper Texas coast & SW Louisiana.

A tropical wave currently over Cuba & the Bahamas is also worth watching as it moves into the Gulf of Mexico.

Conditions are forecast to become more favorable for organization later this week as it moves into the western Gulf, before a final landfall along the Texas coastline Friday into Saturday. There is very little model support for development at this time, but that didn’t stop Imelda last year & Bertha in May from spinning up at the last second.

Regardless of development, the tropical wave will bring better rain chances to the Florida peninsula on Tuesday, and then the west-central Gulf Coast late week. I’ll be watching it.

Meanwhile, a tropical wave between the Lesser Antilles & the Cabo Verde Islands has gotten better organized Monday and has been declared Invest 99L.

Satellite shows increasingly well-defined spin at the surface, though it lacks thunderstorm activity. A brief window for development into a tropical depression or storm exists, but dry air & wind shear will eventually cause 99L to dissipate later this week before reaching the Caribbean.

The next name on the list is Gonzalo, and the recent increase in activity should serve as a reminder the peak of the hurricane season is just around the corner.
