“Atmospheric River” feeds rain, snow in the Northwest Pacific

A strong storm, fueled by an “atmospheric river”, brought rain, snow and the threat of floods and avalanches to the northwest Pacific on Monday.

Weather forecasters said daily rainfall records in Seattle and elsewhere could be broken.

Heavy snowfall and the danger of avalanches have closed the Snokvalmi and Stevens passes, roads over the Cascading Mountains that connect Western Washington and Eastern Washington.

The Northwest Avalanche Center has issued warnings for almost all of its forecast zones. “Running a roller coaster will probably be big enough to bury or kill you. Avoid traveling in avalanches or below, ”the center said.

The floods lasted until Wednesday for rivers across Greater Seattle. The Skokomish River in Mason County was at the level of a flood Monday morning, and dozens more are expected to rise by Monday night or Tuesday morning or Monday morning.

The flood was also issued for the northwest coast of Oregon.

Seattle’s daily rainfall record for February 28 was set in 1972 at 1.46 inches (3.7 centimeters). But a local forecaster said that by Monday it could be broken.

Atmospheric river storms are fueled by long and wide plumes of moisture drawn from the Pacific Ocean.
