Observer Comments
Weather
32F and snowing hard (~.5”/ hr) at the parking lot. Winds were calm at 1,000’ though the ridge top wx stations paint a different picture!
Visibility began to clear out after about 3:30p.
Snow surface
Moist powder. 8-10” new snow.
Snowpack
HS=140cm. ~1,000’ lookers left of the Seattle ridge uptrack. East aspect. 25 degree slope.
Density change at beginning of storm (down 8-10”) was producing consistent results in the snow pit. ECTP2, 4. Really not much of a slab formed yet in the upper snowpack.
More concerning was a layer of buried surface hoar down ~70cm above a decomposing crust. Snowpit results were varied ECTP9,17,29. All propagated the full width of the pit wall.
Top layer shows today’s storm interface. Bottom layer shows buried surface hoar above a decomposing crust.
A solid 4’ on the snow take at the DOT lot. Good start to the season!
Snowing about a half inch an hour for most of the day.
