Get your umbrellas ready. There are chances for rain in Austin from Tuesday to Friday, according to the National Weather Service.

The best chances for rain will come Wednesday — on Juneteenth — continuing into Thursday, with daily temperatures dropping into the upper 70s and low 80s. The week’s maximum daily heat indexes will range from 87 to 105 degrees.

Rainfall ranging from 2 to 5 inches is expected over a 48-hour period from Wednesday to Friday, said Monte Oaks, a meteorologist with the National Weather Service. There could be some minor flooding and swollen creeks and rivers, he said.

Over the next seven days, there is a 70% chance for a tropical storm in the Gulf of Mexico area, meteorologist Jon Zeitler said. However, there’s also a 30% chance that nothing will form, he said. The weather service is unsure of the storm’s potential severity and location.

“We’re expecting a tropical depression to possibly form by midweek and then maybe strengthen to a tropical storm at the end of the week,” Zeitler said. “Were it to become a tropical storm and head to Texas, then we’d be expecting even higher rainfall amounts than they already are.”
