Avalanche Risk Calculator

PORT CALCULATOR Avalanche Risk Calculator Calculate the avalanche risk based on slope steepness and recent snowfall.
📖
What is the Avalanche Risk Calculator & How does it work?

Avalanche risk is influenced by several factors, including the steepness of the slope and the amount of recent snowfall. The steeper the slope, the more likely it is for an avalanche to occur. Additionally, heavy snowfall can increase the likelihood of avalanches.

R = frac{S times N}{10}
R = Avalanche Risk Index
S = Slope Steepness (in degrees)
N = Recent Snowfall (in inches)

The formula above calculates the avalanche risk index by multiplying the slope steepness by the recent snowfall and dividing by 10. A higher index indicates a greater risk of an avalanche.

Frequently Asked Questions
How do I use the avalanche risk calculator?
Enter the slope steepness in degrees and the recent snowfall in inches into the calculator to get the avalanche risk index.
What does the avalanche risk index represent?
The avalanche risk index is a numerical value that indicates the likelihood of an avalanche occurring, with higher numbers representing greater risk.
How steep should a slope be to consider it high-risk for avalanches?
Slopes steeper than 30 degrees are generally considered high-risk for avalanches, especially with significant snowfall.
Can this calculator predict when an avalanche will occur?
No, the calculator estimates risk based on current conditions but cannot predict exact times or locations of avalanches.
What factors besides slope steepness and recent snowfall affect avalanche risk?
Other factors include temperature, wind patterns, and the type of snow. These can influence stability and increase the likelihood of an avalanche.
