Record rainfall has caused part of southern Louisiana to flood early Tuesday—and some areas could get up to 20 inches of rain. A flood warning has been put into effect until Tuesday, as the National Weather Service estimated 12 to 18 inches of rain is likely, with some areas getting up to 20 inches. Floodwaters crested overnight in Bayou Vermilion at Carencro at five and a half feet over flood stage—12 inches above the record, set in 2004. Emergency workers said there had been an estimated 150 rescues so far, including 16 middle-school students whose bus got stuck in more than four feet of water. A state of emergency has been issued in St. Landry Parish, where officials estimated that at least 2,000 people have been affected.
