The bright red blob off the coast of Costa Rica is a center of low pressure that may become a tropical depression or even Tropical Storm Ida by the end of the week. Long-range computer models indicate that as the low creeps up through the Caribbean, it may bring squally rain to the Florida panhandle by the middle of next week. Strong upper-level winds will steer this system away from Houston.

However, the other circled mass of clouds in the southern Gulf of Mexico (the Bay of Campeche) has a good chance of bringing us our next rain chance by late Sunday or during the day Monday. It won't become an organized tropical system however.

While it's rare to have a tropical system in November, it has happened before. This plot shows all of the tropical storms and hurricanes that have formed in the Gulf and Caribbean since 1861:

As you can see, it's more likely for a system to develop in the Western Caribbean, but there have been hurricanes in the Gulf of Mexico. I've marked two of them: Jeanne in 1980 and Juan in 1985, which came into southern Louisiana. There has never been a land-falling tropical system on the upper Texas coast in November and I doubt that record will be set with either of the two blobs out there now.
