Wet gift: It’s going to be a soggy Christmas Eve in Las Vegas

Christmas Eve has arrived and so has the rain for the Las Vegas Valley.

A fire hose of tropical moisture from the Pacific Ocean is bringing widespread showers to Southern Nevada.

The valley is under a flood watch until 4 a.m. Christmas morning, with rain expected for much of today. Las Vegas saw some light showers Tuesday.

The valley should see around an inch of rain, said Clay Morgan of the National Weather Service. Rainfall totals are forecast at up to 4 inches on south-facing slopes of the Spring Mountains.
