The National Weather Service has issued flash flood emergencies for parts of Southeast Texas, including Beaumont and Port Arthur.
KFDM-TV reports the situation in Port Arthur is dire as homes were expected to fill with rising floodwaters and residents unsure of how to evacuate the city.
Jefferson County Sheriff Zena Stephens tells the station that county resources cannot get to Port Arthur because of the flooding and some residents have gone into survival mode.
Mayor Derrick Freeman said on his Facebook page that the "city is underwater right now but we are coming!" He also urged residents to get to higher ground, but avoid becoming trapped in attics.
Deputy Marcus McLellan says city's 911 system has been inundated with calls, which are bouncing to other law enforcement agencies. McLellan says the sheriff's office is working to relay those calls to the proper authorities in Port Arthur.
