MT SHASTA - towers over neighboring mountains, it tends to “create its own weather.” Moisture condenses on the mountain forming lenticular clouds, so even on clear days the mountain can be covered by clouds. Weather conditions can change rapidly on the mountain, especially in winter.

The Five Red Flags of Avalanche Danger any time of year include: 1) Recent/current avalanche activity 2)Thumping sounds or shooting cracks 3) Recent/current heavy snowfall 4) Strong winds transporting snow 5) Rapid warming or rain on snow. (Info from Mt Shasta Avalanche Center)

Shasta Lake Helen

Isaiah 55:9-11
As the rain and the snow come down from heaven, and do not return to it without watering the earth and making it bud and flourish, so that it yields seed for the sower and bread for the eater, so is my word that goes out from my mouth: It will not return to me empty, but will accomplish what I desire and achieve the purpose for which I sent it.
