The Southeast Texas city of Beaumont, home to many huge oil refineries, had recorded nearly four feet of rain by Wednesday morning, according to the National Weather Service.

Mayor Derrick Freeman of Port Arthur, Tex., posted on Facebook that “our whole city is underwater right now.” Motiva shut down its Port Arthur plant, the country’s largest refinery, as the storm flooded the city.

Lake Charles, La., had more than a foot of rain, and storm surge threatened areas along the coast. The National Weather Service warned Wednesday of “catastrophic and life-threatening flooding” that would continue from west of Houston into southwest Louisiana for the rest of the week. Vulnerable New Orleans is not in Harvey’s path, but the right-side rain bands will drench the city.
