Following the weekend’s heavy rain and flash floods in the Southwest, more than nine million people across the southern Plains, including the Dallas-Fort Worth metroplex and Shreveport, Louisiana, are under flood watches as of Sunday.
On Sunday morning, heavy rain began falling across the state line between Texas and Oklahoma and is expected to continue into Monday, bringing with it an additional 4 to 8 inches of rain. It’s possible that areas will get more than 8 inches of rain and experience flash flooding.
The National Weather Service office in Fort Worth/Dallas issued a warning, “We do not know which areas will receive the 8+ inches of extreme rainfall, but if it does occur near you, significant flash flooding will result.”
The weather service has advised that those living in the “watch area” allow more time for their Monday morning commutes.
The Weather Prediction Center has issued a Level 3 out of 4 “moderate risk” of excessive rainfall for much of northern Texas, where as much as 3 inches of rain could fall in an hour during the heaviest storms on Sunday.
The Center noted that while “much of this rainfall will be beneficial and welcome due to the effects of an ongoing drought,” flash flooding could still occur in urban areas and places with poor drainage.
Ninety percent or more of Texas is in a drought right now, with nearly 62 percent in an extreme or exceptional drought.
Later on Sunday, additional flood watches may be issued for nearby areas.
After flooding in the Southwest on Saturday, rain persisted in some parts of Arizona and New Mexico on Sunday.
On Friday, a flash flood in Zion National Park, Utah, “swept off their feet” several hikers. The park reported on Saturday that search and rescue workers were still looking for a missing hiker near the Virgin River.
According to a Facebook post from the City of Carlsbad, New Mexico, about 160 people were forced to take shelter in place for several hours at Carlsbad Cavern National Park on Saturday due to flash flooding.
According to the National Park Service, the park will be closed on Sunday.
The National Park Service also noted that “maintenance crews will begin to assess and clean debris from the roadway.”
