Van Dam said the Houston area will see up to 3 in. of rain on Saturday, May 18. The rain will heard toward Alabama and the southern Appalachians over the weekend and as the storm moves east, they could produce more flash flooding, according to Van Dam.
Other states also experienced flash flooding. “In Pearl County, Mississippi, a train on the Norfolk Southern line derailed Saturday morning when the tracks washed out due to flash flooding,” said Danny Manley, Pearl River County Emergency Management.
Fortunately, no one was injured and the incident did not cause any road closures. According to WTVA, the train compartments were mostly empty. Some Texas residents said the damage was similar to tornadoes that hit the area on Thursday night, according to KTRK.
According to WTVA, some residents were stranded after the roads flooded on Friday night. Some had to spend the night at nearby gas stations, as they were unable to return home.
"I would plead to everybody, if you know there's high water coming up where you are, just stop," a driver told KTRK.
