A powerful early-season snowstorm has buried parts of Montana under up to 2 feet of snow, toppling trees, knocking out power and breaking long-standing October snowfall records.

At Great Falls, 6.4 inches (16.3 cm) fell on October 10, breaking the day’s previous record of 2.1 inches (5.3 cm), set in 1972.

The following day brought another 9.3 inches (23.6 cm), smashing the October 11 record of 3.2 inches (8.1 cm) from 1899—and becoming the city’s snowiest October day on record.

The two-day total reached 15.7 inches (40 cm), ranking as the ninth-largest two-day snowfall in Great Falls’ 134-year record, dating back to 1892.

Temperatures collapsed too. Great Falls tanked from 81F (27C) on October 9 to a high of just 32F (0C) on October 11.

Elsewhere, 24 inches (61 cm) settled near Stanford, 19 inches (48 cm) near Checkerboard, and 17.7 inches (45 cm) near Montana City. Helena received 1.9 inches (4.8 cm), which bested the daily record of 0.5 inches (1.3 cm), set in 1969, in books back to 1880.

The storm developed as cold air drove south into the northern Rockies, interacting with a surge of Pacific moisture, partly associated with the remnants of Hurricane Rachel.

Farther south, snow also reached Utah’s Wasatch Mountains on October 12, whitening slopes at Alta, Snowbird, Brighton and Solitude. Brighton was forced to close its remaining summer activities, with further mountain snow expected through Wednesday.

Heavy early-season snow has hit the western U.S., leaving more than two feet on Utah’s peaks and bringing skiable powder to Colorado’s mountains.

An October 14 survey at Utah’s Alta found snow depths exceeding 24 inches atop Mount Baldy at 11,000 feet, with 18 inches measured at 10,200 feet.

Resort snow stakes recorded 18 inches at Snowbird, 16 inches at Alta and nearly 14 inches at Solitude.

The storm also delivered exceptional moisture, with the National Weather Service reporting 6.52 inches of precipitation at Little Cottonwood Canyon’s Elberts station and 5.87 inches at Alta-Collins over the multi-day event.

Farther south, Silverton Mountain in Colorado was already delivering natural powder turns on October 14, despite its official opening remaining more than two months away.

Heavy rain from Tropical Storm Rachel drenched the Las Vegas valley on Sunday morning, causing widespread flooding.

More than one inch of rain fell early in the morning on the west side of the valley, which prompted a Flash Flood Warning. Another half an inch of rain fell on the east side of the valley during the same time frame.

Harry Reid International Airport picked up 1.08 inches of rain, setting a new daily record. The previous record was 0.78 inches in 2012.

Our cameras captured floodwaters across Las Vegas, leaving cars stranded and forcing road closures.
