LOUISVILLE, Ky. – Almost half a million Americans from Kentucky to Michigan were in the dark Sunday after a massive front dumped heavy snow across much of the nation’s northern tier and slammed parts of the South with powerful thunderstorms and tornadoes.

At least 13 deaths were reported from the storm, which began by dumping several feet of snow in California’s mountains and pushing east, AccuWeather said.

Five deaths were confirmed in Kentucky as wind gusts surpassing 70 mph downed trees and power lines and damaged homes and other buildings, Gov. Andy Beshear said. Power crews in Louisville and around the state labored Sunday after Friday’s high-speed wind storm turned off the lights for hundreds of thousands of Kentucky residents.

The system spawned straight-line winds, possible tornadoes and powerful thunderstorms in parts of the South. More than 173,500 homes and businesses were without power Sunday night in Kentucky, according to the tracking website poweroutage.us. About  71,400 were dark in Michigan and some 30,000 in Tennessee.

Developments:

►Deaths were also reported in Alabama, Arkansas, Indiana, Michigan, Mississippi, and Tennessee.

►More than a foot of snow fell in parts of New York, Vermont, New Hampshire and Maine.

Silver lining for stormy California

California’s mountains are expected to get more snow Monday, and the state’s drought recovery already has been “phenomenal” this winter, weatherbug.com reports. The average water equivalent in the snowpack in California’s mountains range from 40 to 46 inches – almost double the average for early March, the website says. For the first time in years, less than half the state’s land area is in moderate drought or worse.
