9,943′ Tioga Pass & 9,624′ Sonora Pass in California have both closed today for the second time since they officially opened for the summer on April 17th. That April 17th opening of the two passes was one of the earliest pass openings in history due to this being the lowest snowfall winter on record.
Tioga and Sonora passes are closed due to a large snowstorm from the Gulf of Alaska that is hitting California today. That storm is forecast to continue to snow on the passes through tomorrow.
Both Tioga and Sonora passes closed last week for three days due to a big snowstorm that hit and dropped 18″ of snow on Mammoth, CA.
We have a friend who was up on Sonora pass this past Tuesday and he reported decent coverage but hard snow due to the new 18″ of snow there having melted then frozen.
