A winter storm warning is in effect for the Portland area until Friday morning, warning of “heavy mixed precipitation. Total snow and sleet accumulations of 1-3 inches and ice accumulations around a tenth of an inch. Winds gusting as high as 45 mph.”

The National Weather Service NEXRAD radar in Portland that tracks rain, snow and sleet across northwest Oregon went out for about five hours Thursday morning but was back on by about 10:40 a.m., officials said.

As the city faces inclement weather, OHS advises people to keep their pets indoors as much as possible — especially when temperatures drop below 30 degrees. Animals could otherwise face injuries, frostbite or disorientation. These risks are higher for younger or senior animals.
