A powerful winter storm system moving across the Great Lakes and Northeast is bringing snow and ice, frigid temperatures and possible whiteout conditions.

The National Weather Service issued a winter storm warning at 1:55 p.m. on Monday valid from Tuesday 4 p.m. until Thursday 10 a.m. for South Central Oregon Cascades.

"Another round of freezing rain will move in this evening through early tomorrow morning, with icy & slick travel expected as it falls and afterwards," the NWS Twin Cities says. "Temps will be very close to freezing, and how much ice ends up accumulating will be closely tied to how warm we are."

The rainfall has caused widespread reports of minor flooding, primarily with water pooling on roadways, Kennedy said. In the East Bay, flooding impacted Fremont, Union City and Dublin. There were also reports in San Jose, Redwood City and Menlo Park, as well as a number of reports in the Santa Cruz mountains.

A winter storm warning was released by the National Weather Service on Monday at 1:55 p.m. valid from Tuesday 4 p.m. until Thursday 10 a.m. for Eastern Douglas County Foothills.

Strong winds will make travel difficult on Monday, and forecasters warned of more than half a foot of snow on some mountains.

In its report, Pennsylvania’s Public Utility Commission found that the widespread outages stressed Duquesne Light Company in multiple ways. For example, it took the utility company 10 days to restore power to all its customers, which PUC says is the same amount of time it took electric companies to restore service after Hurricane Sandy.

The Great Plains, including parts of Texas, has become an epicenter for severe storm activity, according to a new report. Environmental insights firm AEM just released its annual lightning report, which uses detection technology that recorded nearly 430 million lightning pulses within 88.
