Heavy rain flooded several off-ramps along the eastbound Interstate 2 frontage road in the Weslaco and Mercedes area, leaving some vehicles stranded on Monday, according to the Texas Department of Transportation.

TxDOT crews closed off the affected off-ramps and are continuing to monitor forecasts and road conditions through the evening and overnight, according to a news release.

Crews are prepared to close any state highways that may be impassable due to flooding.

A second round of rain is expected on Monday night, which could bring more flooding to the area.

"Please don't drive around the barricades. They're there for your safety," TxDOT spokesman Ray Pedraza said. "Turn around. Don't drown.”

Driving around barricades is illegal, and drivers can face fines.

Motorists should limit travel if possible. Road conditions can be monitored at DriveTexas.org.
