How Rainfall Impacts Snow Contracts
In most commercial winter maintenance contracts, rainfall is converted toward snowfall caps using the following industry standard:
Every 10 mm of rain = 1 cm of snow:
Using that formula: 177.8 mm of rain ≈ 17.8 cm of snow equivalent
When added to recorded snowfall:
192.1 cm snowfall + 17.8 cm rain equivalent
209.9 cm total snow-equivalent accumulation
⚠️ Note: Conversion formulas may vary depending on your contract terms.
Why This Matters for Commercial Property Owners
Tracking snowfall and rainfall accurately is critical for:
- Seasonal snow cap contracts
- Budget forecasting
- Service frequency expectations
- Salt and material planning
- Transparent reporting
Using official Environment Canada YOW data ensures consistency and avoids disputes when calculating seasonal totals.
