The powerful storm that shut down major highways and knocked out power to thousands of people across the United States continued to make its presence felt on Wednesday morning.

Portions of northern Wisconsin and Michigan remained under winter storm warnings and various flooding and flash flooding watches and warnings were issued in the mid-Atlantic and South as a storm that brought heavy snow and rain, high winds and tornadoes moved east.

According to the National Weather Service, double-digit snow totals have been recorded in 14 states — Arizona, California, Colorado, Iowa, Kansas, Michigan, Minnesota, Nebraska, Nevada, New Mexico, South Dakota, Utah, Wisconsin and Wyoming — since Saturday, while wind gusts have surpassed 50 mph in eight states in the southwest, Rocky Mountains and Great Plains.

Meanwhile, the National Weather Service’s Storm Prediction Center received 15 reports of tornadoes in Alabama and Mississippi late Tuesday and early Wednesday. It’s possible that some of those are referring to the same tornado, as they stemmed from just six counties.

The accounts indicated that roofs were blown off houses in Beaverton, Alabama, and near Collinsville, Mississippi. Other reports said twisters toppled trees and damaged buildings.

Alabama Power said about 14,000 of its customers were without power early Wednesday morning, though was down to 6,400 a few hours later. Georgia Power reported about 1,700 customers near Atlanta were without power, and there were scattered outages in Mississippi.

The tornadoes and power outages were the latest impacts of the powerful storm, which had previously been blamed for thousands of power outages in California and Nebraska.

On Wednesday, National Weather Service showed rain stretching from Alabama all the way northeast to Maine. Heavy rain was falling in parts of Alabama, Florida, and Georgia, where flash flood watches were issued. Other flood watches or warnings are scattered along the east coast, including the Washington and Baltimore areas that were recently hit by a major blizzard.

The Weather Channel is calling this storm Winter Storm Kayla.

Those in the storm’s path are encouraged to monitor their local forecasts.

Parts of Mississippi have received more than seven inches of rain since Saturday, according to the National Weather Service, including 7.73 inches near New Hebron. Selected cities in Alabama, Georgia, Louisiana and Tennessee have all recorded more than three inches of rain.

Snow totals were far larger.

Some mountain passes in Colorado received more than 30 inches of snow, including 41 inches at Coal Bank Pass and 40 inches near Wolf Creek Pass. Denver was hit by 22 inches of snow.

Heavy winds were expected to generate blizzard conditions in some parts of the midwest.

The Colorado Department of Transportation shut down several roads as a result of the storm, including a 300-mile stretch of Interstate 70 that began in Denver and stretched into Kansas, though most reopened later Tuesday. Some state highways remained closed in Kansas and Nebraska on Wednesday morning, their state transportation departments reported, and many roads in southern Minnesota and Northern Iowa were still completely covered with snow or ice.

Parts of Minnesota received more than a foot of snow, the National Weather Service reported.

The Minnesota State Patrol said that Interstate 90 and many other highways in the southern part of the state were closed on Tuesday, though they were open again on Wednesday morning. A spokesman tweeted that troopers responded to 449 accidents in a 24-hour period statewide.

Flight monitoring website FlightAware.com indicated that more than 240 flights to or from Minneapolis/St. Paul International Airport were cancelled on Tuesday and Wednesday morning.

While some interstates reopened, others were still closed.

That included a 200-mile stretch of Interstate 80 in Nebraska that spanned from North Platte to Beaver Crossing, according to the state Department of Transportation.

The National Weather Service’s flood warnings and watches issued for the mid-Atlantic and South warned rivers and streams could breach their banks, which may cause additional road closures.
