Tropical Storm Arlene formed in the southwestern Gulf of Mexico on Tuesday, making it the first named storm of the Atlantic season.
The U.S. National Hurricane Center says satellite images show the centre of Arlene making landfall near Cabo Rojo Thursday morning. Weakening should continue throughout the day on Thursday as the storm moves inland.
Still, flooding could become an issue along the central Gulf coast of Mexico with up to 200 mm of rain possible. There's the potential for locally higher amounts over mountainous terrain. Authorities warn of life-threatening flash floods and mudslides with these heavy downpours.
Arlene could also bring some much-needed rain to drought-stricken south Texas.
The government of Mexico replaced the tropical storm warning with a hurricane warning for the coast of northeastern Mexico on Wednesday. Areas from Barra de Nautla northward to La Cruz are at risk.
The first two hurricanes of the Pacific season were Adrian and Beatriz. Storms are named before they're born. Check out what this season's storms in the Pacific and Atlantic will be called.
