⚡️❄️ NEW - More than 5 feet of snow has been dumped on Mammoth, California, in just the past 72 hours.

At about 730 am this morning, two ski patrollers were caught in an avalanche while they were performing avalanche mitigation work.

One sustained broken bones, and the other was rushed to the hospital with "serious injuries."

The area is expecting another 12 to 18 inches of snow with wind gusts up to 55mph.

The sign at the top of the mountain, which stands 24 feet tall, is nearly covered with snow.
