USA weather MAPPED: MILLIONS under winter alert – More snow to SMASH the USA this week


Severe wintry weather is expected to continue this week as more than 75million people have been put under winter alerts. The weather system, named Winter Storm Nadia, dumped more snow on the already blanketed Pacific Northwest on Monday and Tuesday, and is currently spreading a wintry mess over the Sierra, Siskiyous, Cascades and northern Rockies, according to CNN. More than three to four inches of snow were measured in California on Tuesday night.

The freezing temperatures have forced the National Weather Service (NWS) to issue winter storm warnings, watches and winter weather advisories across the nation.

The warnings stretch from the Northwest into California’s Sierra Nevada and the northern Rockies.

NWS is also warning of increasing moisture going into Colorado later on Wednesday with the strong winds aloft to produce moderate to heavy snowfall in the mountains tonight and Thursday morning.

In the advisory, NWS warns: “Windy conditions are expected through today, and the addition of snowfall tonight will make for hazardous travel conditions through the Colorado high country later tonight into Thursday morning.

“The gusty winds will produce areas of blowing and drifting snow with very low visibilities at times.

“The heaviest snow amounts are expected to be in the mountains of Grand and Jackson counties, with lesser amounts in North Park and Middle Park.

“Snow amounts will be lower in Summit County, but blowing and drifting snow will still make travel difficult overnight.”

Meanwhile, high pressure over southern parts of the US will maintain dry and seasonable conditions in the region through midweek before a small storm develops over the Plains on Friday.

AccuWeather Meteorologist Brett Edwards said: “Snow will swing down across the Plains and into the Ohio River Valley before moving off the mid-Atlantic coast.”

The weather service warns the storm will promote wintry conditions over Nebraska and Kansas by midday on Friday before spreading to Missouri and southwestern Illinois in the evening.

Mr Edwards added: ”Any snowfall can create slippery road conditions and result in travel delays.”

While snow is not expected to last longer than 12 hours in any one location, several inches of snow can accumulate in that time.

As the weekend approaches the storm will move across the mid-Atlantic and batter areas including Philadelphia, Washington DC and Baltimore.

These cities could receive a few inches of snow on Saturday evening and Sunday morning.

New York City may be on the northern edge of the snow.

Mr Edwards said: ”While totals will not be very high, many roads will still likely be snow packed and slick.”
