Drenching rain along the Texas-Mexico border let up Friday, but rescues were still ongoing a day after severe storms trapped residents in their homes, forced drivers to abandon their vehicles on flooded roads and shut down an airport.

Alamo emergency responders handled more than 100 water rescues, including people trapped in homes and stranded in vehicles.

Weather forecasters are predicting an upper-level disturbance to approach Houston from the west and to cause some thunderstorms and heavy rainfall.
