The 2021 Atlantic Hurricane Season is heating up and it’s heating up fast. An area of disturbed weather in the southern Gulf of Mexico is showing signs of organization.

Here’s what you need to know:

  • As of Wednesday, rain and clouds around a trough of low pressure in the Bay of Campeche have a 90% chance to become organized into a tropical depression or tropical storm in the next five days. Formation could happen as early as Thursday (6/17) or Friday (6/18).
  • Regardless of formation, heavy rainfall will be possible over Central America and Southern Mexico for the next several days.
  • As of now, all indications are that the bulk, if not all of the moisture associated with this tropical system will stay east of South Texas. This will keep the weekend hot and dry in San Antonio.
  • Those along the coast in far East Texas and Louisiana should monitor the development of this system closely.

2021 Atlantic Hurricane Season Names

Should the disturbance in the Gulf become organized and strengthen into a tropical storm, with wind speeds of 39 mph or greater, its name would likely be “Claudette”.

Below is a list of names that will be assigned to tropical storms or hurricanes this season. NOTE: Tropical Storm Ana formed earlier this year, in late May.
