The National Hurricane Center announced earlier that Hermine was gaining strength as it neared land, with its top sustained winds growing to 65 mph (100 km/h) before hitting shore.
Hurricane Hermine is heading for the area around Brownsville, Texas and Matamoros, Mexico, where the border meets the Gulf of Mexico. People on both sides of the border are preparing for a possible meter-high surge of water, heavy winds and torrential rain.
The Mexican authorities urged people living in low-lying coastal areas to move to shelters while officials in Texas distributed sandbags and warned of flash floods.
Hurricane Hermine, whose force winds reach 105 miles from its eye, may bring four to eight inches of rain to northeastern Mexico and southern Texas, with isolated areas getting as much as 12 inches.
The NHC has issued a hurricane watch for the coast of Texas from the mouth of the Rio Grande River to Baffin Bay. A hurricane watch means that hurricane conditions are possible within the watch area, in this case, within 24 hours.
