Texas braces for tropical storm forecast to bring heavy rain, winds, tornado threat

Updated

An anticipated tropical storm is expected to bring heavy downpours, high winds and the possibility of tornadoes to southern Texas and the Rio Grande Valley on Wednesday.

A tropical cyclone is expected to strengthen into a tropical storm before arriving in northeastern Mexico by Wednesday evening, according to the National Weather Service. Tropical storm conditions with wind gusts up to 57 mph are expected along the Texas coast south of the San Luis Pass.

Heavy rainfall and the threat of flash floods will intensify in the western Gulf Coast, according to National Hurricane Center Director Michael Brennan.

"Major rainfall flooding may prompt many evacuations and rescues," the weather service said. "Rivers and tributaries may rapidly overflow their banks in multiple places. Small streams, creeks, canals, and ditches may become dangerous rivers. Flood control systems and barriers may become stressed."

The cyclone is predicted to bring rainfall totals of 5 to 10 inches from northeastern Mexico to south Texas, possibly peaking at 15 inches. The weather service's office in Brownsville, Texas reported a 40% chance of rapid onset flooding Wednesday with rainfall totals of 2 to 3 inches possibly lasting hours.

The National Weather Service said that "the situation is somewhat favorable for tornadoes" and warned residents to seek safe shelter.

Forecasters said the eventual storm is expected to weaken upon landfall Wednesday night and diminish by Thursday evening. More downpours will continue across the Rio Grande Valley and south Texas on Thursday before conditions improve.
