NORDEN, Calif. (AP) – The search for a ski instructor who went missing at a Northern California ski resort has been suspended until morning, following a day hampered by bad weather.

The Placer County Sheriff’s Office says avalanche danger was high Sunday and stormy weather kept searchers from looking for 23-year-old Carson May by air.
