AUSTIN -- Austin city crews are monitoring low water crossings as rain picks up across the area.
On Monday crews first stopped at a low water crossing at Bull Creek in Northwest Austin. Officials say it doesn't take long before the creek fills up and water flows over the road.
The crews are checking the warning signals, which are designed to turn on automatically when the water hits a certain level. However if the switches don't work, crews can activate the lights as a warning to drivers.
“We can monitor the sites from our computers and we can tell when a road is flooded. We can activate our lights by cell phones; we have an app on our cell phones and we can activate and we can do it manually too at the site,” said electric tech with the City of Austin Car Cannon.
Cannon and other crews are also checking the low water crossings and cutting back overgrown brush to make sure drivers can see the signs and the water level.
Cannon says crews will visit all low water crossings Monday. There are 14 across the city of Austin.
Central Texas is under a Flash Flood Watch until Tuesday at 7 a.m.
