Its breaking news on King5, there was a slide in the Lake Wenatchee area (Kahler Glen) that destroyed one home and they've evacuated 15 other homes. The slide came down the steep Mason Ridge. Snow's getting heavy and sliding so be careful out there.
Lake Wenatchee Be Careful
- Thread starter sky7051
- Start date
It's gotta be bad if that area is sliding.
Nason Ridge
Yeah I just saw that Blue... ooops. Was talking at work about a job in Manson and trying to type Nason at the same time. Anyone got anymore news on the slide?
check the avy forecast
this is the detailed forecast. the summary forecast is for high danger. i would think it is possible to get to extreme danger level in the next few days. check the nwac.org website daily
the avy danger is high. with the weather forecast i dont think it will lower in the next few days. it will increase slighly or could go to extreme before it settles back down to considerable or moderate. Please check the danger level daily.

MOUNTAIN WEATHER FORECAST FOR THE OLYMPICS WASHINGTON CASCADES

NWAC Program administered by:

with cooperative funding and support from:
Washington State Department of Transportation

WEATHER SYNOPSIS FOR THURSDAY AND FRIDAY
A very strong cold front has moved across the Olympics near
midnight last night and crossed the Cascades early Thursday
morning. The front produced heavy precipitation at rising
freezing levels with brief rain or freezing rain reported at
Snoqualmie Pass early Thursday. A very strong westerly jet
stream also strengthened winds with the frontal passage with
several NWAC telemetry stations reporting gusts over 100 mph
early Thursday.
Freezing levels have begun to lower behind the front
Thursday morning with winds and precipitation gradually
decreasing. However, the strong and moist westerly flow
should maintain moderate to heavy orographic precipitation
along the typical west slope areas Thursday. The mid level
flow actually increases overnight Thursday and early Friday
morning. Coupled with abundant low level moisture, this
should maintain moderate to heavy precipitation over the
west slope areas of the Olympics, Cascades as well as the
over the volcanic peaks through mid morning Friday. This
flow pattern should also allow a convergence zone to form
overnight Thursday and early Friday to enhance precipitation
over the central Washington Cascades, centered on about
Stevens Pass.
Warm frontal moisture from the next approaching weather
system should cause increasing steady precipitation at
rising freezing levels Friday afternoon and night. The snow
level should rise above the Snoqualmie Pass level but remain
just below Stevens and White Pass Friday night.
