#NOAA / #NWS winter weather advisories for the mountains of !SoCal’s #San_Bernardino and #Riverside counties: up to two inches of snow above 5,000 feet and 45-60MPH wind gusts along mountain crests and desert slopes. Plan on slippery roads, reduced visibility, downed tree limbs.

(They don’t mention the #I-15 or Cajon Pass at all, so it may not have a big effect on traveling to celebratory gatherings.)
