The Bottom Line

We’re back in the office prepping weather stations and waiting for winter to arrive. Much of the snow from last week’s storm has melted off sunny slopes. With warm temperatures and sunny skies continuing, old snow will only hang on at the highest elevations on shady, north-facing slopes.

We will update this General Avalanche Information product when more snow accumulates.

Fall Gear Check
Use this dry week to go through your kit at home:

Beacon: Put in fresh batteries of the type your manufacturer recommends, check for corrosion and cracks, update the firmware, and do a practice search with your partners!
Airbag: Practice-deploy it if your manufacturer recommends it, then refill or weigh the canister (or charge the battery and update firmware on electric packs) and repack it carefully.
Probe and shovel: Assemble and lock them several times, and check for bent, cracked, or sticky parts.
And all the rest: Restock first-aid and repair kits, charge radios, and check skins, bindings, and crampons.

Gear only helps if your whole team can use it quickly, and it never replaces good terrain choices. Our team is gearing up for the season (with a few new forecasters in tow!) and is excited for the winter ahead.

Today, temperatures will be in the 50s F across the area, with partly cloudy to overcast skies and light winds. Overnight, conditions will shift as cloud cover continues to roll in and bring rain. Temperatures will begin to drop, but not enough to produce snow. As the system moves through our area tomorrow, we will see light snow starting above 7,000'. Most of the snow will fall throughout Friday, with little accumulation, and precipitation will fade by evening. Temperatures will continue to cool into Saturday morning, with cloud cover diminishing.
