Notifications
Hazard notifications
Subscribe to and manage hazard notifications. Needs a user token, not an API key.
Overview
The notification broker manages hazard notification subscriptions on behalf of an authenticated user. Subscribe to hazards for a location, list what is currently subscribed, and unsubscribe.
Delivery is handled by FLASH Weather's alerting pipeline, the same one behind the lightning and hail products, so subscriptions fire on the operational signal rather than a separate polling loop of your own.
Coverage
Forecast alerts, such as heat, heavy rain, snow, cold and wind, and the daily forecast summary are available for locations worldwide. Alert levels follow the local climate, so what counts as unusual heat or heavy rain depends on where the location is and the time of year.
Lightning alerts (lightning detected nearby and the all clear) are sent only inside lightning
detection coverage, which today is the Americas. A location outside it still gets forecast
alerts. Saved locations report this as lightning_coverage, true where lightning alerts are
sent.
forecast_coverage is true where forecast alerts and the daily forecast summary can be
sent.
Typical uses
Alerting integrations that need push rather than poll, and applications delivering severe-weather notifications to their own users.
