# Snowball Weather Commands: /weather Slash Reference

> Complete reference for all /weather slash commands in Snowball — radar, alerts, satellite, forecast, sounding, briefing, cameras, and more with all options.

All weather data comes from NWS and is limited to US locations. Every weather subcommand is slash-command only — prefix commands are not supported. Commands that accept a `location` option use autocomplete: start typing a city name and Snowball will suggest matching locations.
