Lake Charles, Louisiana, was hit harder Monday than any other part of the state. The city’s regional airport (ICAO code: LCH) received a daily record of 12.49 inches of rain, smashing the old May 17 record of 3 inches set in 1914. It was also the third-wettest day on record for the city. The flooding prompted water rescues, and Gov. John Bel Edwards issued a state of emergency.

Flooding hit other areas of Louisiana Monday, as well as portions of eastern Texas. Additional periods of heavy rain could virtually drown areas of Texas, Louisiana, Arkansas and Oklahoma through Thursday. Potential target cities include Brownsville, Austin, San Antonio, Houston, Texarkana, Dallas-Fort Worth and Wichita Falls in Texas; Lake Charles, Baton Rouge, New Orleans and Shreveport in Louisiana; as well as Oklahoma City.
