How do I get weather for a specific city?

First use `search_location` with the city name (e.g. 'Tokyo') to find its AccuWeather location key. Then use that key with `get_current_conditions` for current weather, `get_daily_forecast` for the forecast, or `get_hourly_forecast` for hour-by-hour details.

What's the difference between daily and hourly forecasts?

Daily forecasts (1-15 days) give you one summary per day with high/low temperatures and overall conditions. Hourly forecasts (12-120 hours) give you weather for each individual hour — perfect for knowing exactly when rain will start, when temperatures peak, or the best time for outdoor activities. Use hourly for precise timing, daily for general planning.

Can I get severe weather alerts?

Yes. Use the `get_weather_alarms` tool with a location key to check for active severe weather alerts. This includes hurricanes, tornadoes, flood warnings, heat advisories, winter storm warnings, and more. Returns empty if no active alarms. Essential for emergency preparedness and travel safety decisions.
