Mountain Conditions and Weather Report
Date: Apr 24, 2025
Time: 17:15
Location: STSG
Current Snow Conditions:
No measurable snowfall in the past 12 hours, with average temperatures around –1 °C at 1300 m and –3 °C at 1600 m. The spring snowpack remains well-settled and consolidated, though daytime heating and clear skies will likely promote a melt-freeze cycle. Expect firmer snow surfaces in the morning, softening through the day on solar aspects. North-facing slopes may preserve cooler, firmer conditions for longer.
Temperature Trends:
Near treeline, temperatures hover around 7 °C Thursday evening and climb to 10 °C Friday, with a high freezing level rising to 2700 m. By Saturday and Sunday, slightly cooler air returns, with treeline highs of 6–5 °C and the freezing level settling near 2500 m.
Wind Overview:
Winds remain moderate at upper elevations, shifting direction over the weekend. Thursday night sees southeast ridgetop speeds of 20–25 km/h, becoming light and variable (10–15 km/h) on Friday. Northwest winds 15–25 km/h dominate Saturday and Sunday, primarily affecting exposed terrain at higher elevations.
General Forecast:
Clear skies and mostly sunny conditions will persist through the weekend as a high-pressure system remains in place. No new snowfall is expected, leaving the existing snowpack to undergo daily melt-freeze cycles. Expect firm conditions in the morning, turning softer and more spring-like by midday.
Advice:
Early starts will reward you with smoother, firmer surfaces before the snow softens. Don’t forget to pack sunscreen—spring sunshine can be strong. Friday will be a scorcher by alpine standards, so stay hydrated and plan for slushy conditions later in the day. Keep an eye on the Aurora Backcountry Pass Guide Announcements in the Base Camp Forum for updates, and consider hiring a Certified ACMG Ski Guide to help navigate terrain decisions. Enjoy the spring turns out there!

Time: 17:15
Location: Whistler Blackcomb
Current Snow Conditions:
There has been no new snow in the last 12 hours. The snowpack remains around 206 cm near 1650 m. Warmer temperatures are producing soft, spring-like snow on sun-exposed slopes, while higher, shaded aspects may offer firmer conditions earlier in the day.
Temperature Trends:
Temperatures are unusually warm at lower elevations (up to 19.8 °C at 675 m), decreasing to 3.2 °C at 2284 m, indicating a normal lapse rate. Freezing levels are near 2500 m and will likely rise to around 2700 m by Friday afternoon.
Wind Overview:
Current summit winds are moderate (31–38 km/h) from the southeast. They should ease overnight, becoming light and variable on Friday, then remain generally light to moderate through the weekend.
General Forecast:
Clear skies are expected through Sunday, with minimal changes day to day. High freezing levels (2500–2700 m) will preserve firmer snow on upper north aspects in the early morning, transitioning to soft spring snow on sunny slopes by midday.
Advice:
Plan for spring conditions: an early start helps you catch supportive snow before it softens. Remember sun protection, stay hydrated, and watch for rapidly softening surfaces on solar aspects. Keep an eye on the Aurora Backcountry Pass Guide Announcements in the Base Camp Forum, and consider hiring a Certified ACMG Ski Guide if you need assistance managing terrain choices.

Time: 17:15
Location: Duffey
Current Snow Conditions:
Lower elevations around 1250 m have shallow coverage at 42 cm. Surfaces likely see daily melt-freeze cycles and may form a crust each morning. Mid elevations around 1890 m hold a deeper snowpack at 128 cm. Around 3 cm of new snow fell higher up in the last 12 hours—likely settling quickly with the current warm temperatures. Best snow quality will be found on sheltered northerly slopes at higher elevations, where the new snow may retain some softness.
Temperature Trends:
Temperatures follow a normal lapse rate, dropping as you go higher. Recent afternoon highs reached 14.5 °C at 1250 m and 10.6 °C around 1890 m. Overnight lows dipped below freezing, promoting a melt-freeze cycle. Freezing levels are expected to stay around 2500 m Thursday night, rising to 2700 m on Friday, then settling near 2500 m through the weekend.
Wind Overview:
Winds remained light at lower elevations (around 4 km/h). Forecasts call for moderate southeast ridgetop winds (up to 30 km/h) overnight Thursday, then lighter and variable into Friday. Saturday could see light southwest flow, and Sunday a moderate northwest breeze. Exposed ridgelines may experience mild wind-affected surfaces, but overall impacts look limited.
General Forecast:
Expect clear and sunny weather through Sunday with mild to warm daytime temperatures. Overnight refreezes will be modest, given the high freezing levels. No significant new precipitation is on the horizon, so anticipate continued dry conditions with sun-affected slopes softening by midday.
Advice:
Spring conditions dominate. Aim early for firm surfaces and be prepared for softening snow in the afternoon. Sunscreen and layers are essential—temperature swings are likely. Over the next 12–24 hours, warm, sunny skies with calm to light winds should offer pleasant touring if you plan timing around the daily melt-freeze cycle. Keep checking the Aurora Backcountry Pass Guide Announcements in the Base Camp Forum for any updates, and consider hiring a Certified ACMG Ski Guide for managing risk.
