(DALLAS) -- Parts of the southern Plains, western Ozarks and lower Mississippi Valley are at risk of severe weather this week while regions across Texas begin to clean up after 18 reported tornadoes raked a path of destruction across the state, tossing trucks into the air and tearing the roofs off homes and businesses.
The National Weather Service has predicted chances of severe thunderstorms across parts of the mid-Mississippi and Ohio Valleys on Wednesday, which might include large hail, damaging winds and isolated tornadoes. Parts of the southeastern United States might also experience severe weather, according to the weather service.
A severe-storm warning was given for New Orleans overnight as more rain moved in and flooding began on some city streets, with reports of two to three feet of water on roads. A possible tornado touched down in Gentilly, La., early Wednesday, while a roof was blown off a house.
About 650 homes were damaged in Tuesday's tornado outbreak across Texas, according to the American Red Cross. Although there were no fatalities during Tuesday's dangerous weather, 15 people sought treatment at area hospitals and two were involved in auto accidents, according to ABC News' Dallas affiliate WFAA.
Eight Texas counties faced severe weather alerts from the National Weather Service. The counties included Bosque, Dallas, Delta, Hopkins, Hunt, Kaufman, McLennan and Rockwall counties.
