Thick fog envelops Red Rock, mountains

Dense fog temporarily closed Red Rock Canyon Loop on Wednesday afternoon and was expected to blanket parts of the Las Vegas area until Thursday morning.

Fog is common from December to February, National Weather Service meteorologist Andy Gorelow said. But it’s usually seen in the evening or early morning.

“To have it going through the day like this is sort of unusual,” he said.

The fog started to set in just after noon Wednesday, and at times there was “basically zero visibility” in Red Rock Canyon, Gorelow said.

He said Tuesday’s rain and cooler temperatures contributed to the fog, which is expected to last until about 10 a.m. Thursday.

Drivers should use low-beam headlights, not high beams, and should go slower because of reduced visibility, Gorelow said.

There was little fog in the Las Vegas Valley.
