The strongest winds will probably occur from around 10 am this morning through 4 pm this afternoon.
A National Weather Service wind advisory for the valleys around Riverside, the Coachella Valley and the San Gorgonio Pass near Banning is scheduled to remain in effect until 1 p.m. Winds of 15 to 30 miles per hour are possible during the advisory period, along with gusts of 35 to 50 mph.
A Winter Storm Warning is in effect for the West Glacier and Potomac/Seeley Lake Regions – along with the Bitterroot/Sapphire Mountains above 5,500′ from 2 p.m. Tuesday until 11 a.m. Wednesday. The warning is also for the Eastside and Cascade mountain foothills as well as the Strait of Juan de Fuca, Kitsap County, the Olympic Peninsula and the Washington coast.
“The gusty winds will continue to bring the threat for downed trees and branches… especially since many trees have become weakened and diseased due to the long-term drought”, warned an NWS statement. Winds are expected to calm in the morning.
In addition to the wind, we’re looking at another heavy rain event. We’re expecting 5-8 inches of rain during the day, with isolated spots getting even more.
Valleys will see a rain/snow mix (if not all rain) throughout Tuesday with highs in the 40s.
