Heavy rainfall on Monday, June 24, created flood conditions in Hidalgo County, Texas, that the National Weather Service said could persist until Wednesday.
Greg Diamond of the Weather Channel said 8-13 inches of rain fell in less than 12 hours, in a region that normally gets 20-25 inches in an entire year.
The Valley Morning Star reported that dozens of roads were closed in the Rio Grande Valley as flash floods made them impassable.
