California’s About to Get its First Big Atmospheric River of the Season. Here’s Where it’s Going

The strongest atmospheric river to hit California in months is expected to dump rain and snow across the northern half of the state this week — also bringing high winds and possible flooding — before eventually making its way south, forecasters say.

“This is going to be the first major storm of the season,” said Dial Hoang, a National Weather Service meteorologist in Monterey. The low pressure system off the Pacific Northwest coast driving this storm will begin rapidly intensifying Tuesday — reaching the threshold of a bomb cyclone — which will drastically increase its moisture and strength.
