GLENWOOD CANYON, Colo. (KDVR) — Potential mudslides, flash floods and rock slides may cause additional closures on Interstate 70 this week, the National Weather Service warns.

I-70 in Glenwood Canyon will close if a flash flood watch is issued, Colorado Department of Transportation advises motorists.

The Grizzly Creek Burn area is currently under a flash flood advisory.

The Glenwood Canyon recreation path and the Grizzly Creek and Shoshone Power Plan rest areas are closed, CDOT announced on Tuesday.

Back-to-back mudslides forced extended closures on I-70 over the weekend.

People should stay in their vehicle during a road closure, CDOT says.

Flooding safety tips for drivers:

• Never drive through any flooded area, you do not know how deep or how fast the water is running. 
• Even 8-10 inches of water can float an average-sized car, which can be easily swept off the road. 
• Driving too fast on wet roads or in flooded areas can cause a vehicle to hydroplane.
• Never use your cruise control during rainy conditions with standing water on the roadway.
• Any amount of flooding or mud can obstruct the roadway and hinder drivers from knowing exactly where to drive.
• If you cannot see the roadway, be smart and wait for the water to subside.
• Water and mud can contain unknown hazards hidden under the surface – rocks or other debris, like plant material and tree branches.
