UPDATE 11:43 PM MARCH 31: NV Energy reports 1,198 people are without power in Clark County.

UPDATE AT 6:30 PM MARCH 31: NV Energy reports that 2,825 customers remain without power.

People living in McNeil Estates near Charleston Boulevard and Rancho Drive have been without power for well over 24 hours.

"We'll have a big buffet tomorrow of all the frozen food that thawed out that we're going to have to cook tomorrow," said Donna De Luca who lives in the neighborhood.

Others relied on generators to keep their refrigerators working.

While power was restored to two of the Clark County schools as the day continued, parents wanted why school wasn't canceled in the first place.

A spokesperson for the district said it followed protocol by only allowing students to leave if a parent or guardian came to the school to sign them out.

The spokeperson also said school wasn't canceled because buildings were still functional and the weather outside wasn't too extreme.
