The storm, which is heading north into the Gulf of Mexico, is likely to dump five inches (13 cm) to 10 inches (25 cm) of rain with parts of the Gulf Coast and even 15 inches (38 cm ) in isolated areas, according to forecasters from the National Hurricane Center.
In Louisiana, the threat came a month after spring storms and flooding that were responsible for five deaths, and as parts of the state continued to slowly recover from a brutal 2020. hurricane season.
This included Tropical Storm Cristobal which opened the season last June, Hurricanes Laura and Delta which devastated southwest Louisiana, and Hurricane Zeta who fell trees and cut electricity for days in New Orleans in October.
Mexico, while receiving rain from the storm in the Gulf, was also threatened by a storm in the Pacific.
Tropical Storm Dolores formed on Friday and is expected to hit its west-central coast on Saturday evening, possibly near hurricane force, according to the National Hurricane Center.
