I could see the ominous clouds from Twisp River, but we got no rain or lightning close to us. It stayed north. Stay tuned. More tomorrow and Wed. possibly.

I'm pretty sure I got close to an inch of rain that started at 4 and didn't stop until a few minutes ago (7:30 pm). Lots of wind and a whole lot of lightning. I saw mostly cloud to cloud lightning but there were plenty of ground strikes happening.

Very heavy rainfall here presently. I'd expect at least some mudslides and flash floods in the neighborhood.

E edge of the cell is roughly over me, with a bit of rain and very little wind at the moment. Some lightning but I'm not observing any ground strikes yet.

I spoke too soon, sighted one ground strike due S of me some miles distant.

Just popped up

The National Weather Service in Spokane has issued a

* Flash Flood Warning for...
The Cedar Creek Burn Scar in...
Western Okanogan County in north central Washington...

* Until 400 PM PDT.

* At 153 PM PDT, Doppler radar indicated thunderstorms producing
heavy rain over the Cedar Creek Burn Scar. Flash flooding is
ongoing or expected to begin shortly.

Excessive rainfall over the burn scar will result in debris flow
moving through the Cedar Creek Burn Scar. The debris flow can
consist of rock, mud, vegetation and other loose materials.

HAZARD...Flash flooding caused by thunderstorms in and around
the Cedar Creek Burn Scar.

SOURCE...Radar.

IMPACT...Flooding of areas in and around the Cedar Creek Burn
Scar.

* Some locations that will experience flash flooding include...
Klipchuck Campground.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

The affected areas are in and below the Cedar Creek burn scar south
of Highway 20 from Mazama to Winthrop, including the Chickadee
Trailhead and Wolf Creek Road. Some drainage basins impacted include
Cedar Creek, Varden Creek, Little Boulder Creek, Wolf Creek, and
Thompson Creek. Moderate to high intensity rainfall on the burned
area may cause flash flooding, mud slides and rock slides. Campers,
hikers residents, and motorists in and below the Cedar Creek burned
area should take immediate precautions to protect life and property.


This is a life threatening situation. Heavy rainfall will cause
extensive and severe flash flooding of creeks...streams...and
ditches in the Cedar Creek. Severe debris flows can also be
anticipated across roads. Roads and driveways may be washed away in
places. If you encounter flood waters...climb to safety.
