Northern California experienced unusually wet weather for June over the weekend.
Thunderstorms moved through the Sacramento Valley on Sunday with heavy rain, gusty winds and hail in some areas. A funnel cloud was even reported south of Olivehurst.

Heavy snow in the Sierra, which continued overnight and into Monday morning, is causing slippery road conditions and travel delays on Interstate 80 over Donner Pass.
Officials with Caltrans District 3 ask drivers to prepare for winter driving conditions and to take it slow. Chain controls are required on all cars except four wheel, or all wheel, drive vehicles with snow-tread tires on all four wheels.
