Ski Touring Conditions

Get combined avalanche, snow, and weather data for ski touring in the Austrian Alps.

Prerequisites

bash 4.0+ (for associative arrays)
- macOS ships with bash 3.x: brew install bash
- Linux: Usually pre-installed
uv (for coordinate lookup feature)
- curl -LsSf https://astral.sh/uv/install.sh | sh
jq, curl, bc (checked at runtime)

When to Invoke

User asks about ski touring / backcountry skiing conditions
User wants avalanche danger levels for a specific area
Phrases like "skitour", "Lawinengefahr", "snow conditions", "touring conditions"
User mentions Austrian touring areas (Stubai, Rax, Hochschwab, Lech, etc.)

Quick Usage

# Single location by name
./skitour.sh --location stubai
./skitour.sh --location rax

# Single location by coordinates (auto-detects region)
./skitour.sh --lat 47.1 --lon 11.3

# Compare multiple locations
./skitour.sh --compare "stubai,rax,lech"

Coordinate Lookup

When using --lat and --lon, the script automatically determines the correct EAWS micro-region using a Python helper (region_lookup.py) that performs point-in-polygon matching against official EAWS GeoJSON boundaries. This requires uv to be installed.
