Hundreds of flights were canceled Tuesday as a winter storm wreaked havoc on travel and dumped more than two feet of snow in portions of the Northeast.

Meanwhile in the West, soggy California faced more flooding from the latest deluge, and nearly 27,000 people were under evacuation orders due to flood and landslide risks.

“Double-Whammy! Storm-weary Californians are facing another strong Atmospheric River Event and the Northeast is bracing for a powerful Nor’easter,” the National Weather Service tweeted.

Some areas of Vermont and Massachusetts already had over 2 feet of snow as of midday Tuesday. A recurring theme in weather service storm warnings across much of New York and New England: “Significant snowfall and periods of heavy snowfall rates will combine to create low visibility and very dangerous driving conditions.”

The storm targeted parts of New England, New York, Pennsylvania and New Jersey, and hundreds of school districts were shuttered for the day.

Strong winds and the weight of snow on tree limbs could topple power lines and cause power outages, forecasters said. More than 250,000 homes and businesses across New York and New England were in the dark as of Tuesday evening. 

Storm developments:

►More than 25 million Americans were under winter storm warnings, watches or advisories. More than 40 million faced wind advisories or watches.

►When LaGuardia’s ground stop was called off, delays averaged more than 2 hours. Connecticut’s Bradley International Airport also briefly closed because of storm conditions, though 40% of the airport’s flights were canceled.
