This dramatic footage shows a submerged highway and multiple stranded cars in Dallas after thunderstorms have caused severe flash floods. Cassondra Anna Mae Stewart, who filmed the footage, was left stranded for two hours on interstate-30 whilst trying to get home. The video shows multiple cars and emergency vehicles stuck in the flood, which has covered both sides of the highway and even trapped vehicles under the bridge. Cassondra said: “It took me over two hours to get home! It's flooded all over downtown - the highway and the streets surrounding it too. “Luckily I was able to reverse up a ramp nearby and get off the highway so I could actually get home. I’m so glad I’m safe now!” Dallas county has been placed on a flash flood warning, as well as other areas in northeastern Texas, northern Louisiana and southern Arkansas as thunderstorms continue to batter the southwest. This video was filmed in the early morning on 22/8.
