Las Vegas Fire and Rescue is also warning that the cold temperatures and snow can cause the possibility of property damage along with personal injury.

Nighttime temperatures will be at or near freezing and those low temps can cause any wet spots on the ground to become frozen and slippery.

Exposed water pipes could also be damaged by freezing water inside, causing leaks once the water begins to melt, according to Las Vegas fire.

Residents were urged not to use torches or fire to thaw the pipes as this can cause the pipe to explode, and should instead use a hairdryer.

Las Vegas fire also said as a reminder that pets should be brought inside and not exposed to the cold air for extended periods.

The National Weather Service updated the snowfall was already between a half inch and 1-inch in the west part of town above 2500 feet just before 7:30 p.m.

With most of the roads wet and temperatures west of the 215 Beltway approaching the freezing mark.
