Alerts, Watches and Warnings

Similar to the bulletins put out by the NWS local forecast offices, SWPC provides Alerts, Watches and Warnings to the public at large about what to expect from Space Weather. These bulletins are levels of severity of the solar activity that can be expected to impact the Earth’s environment.

Previous text files of the alerts and Warnings page are available.

The current Alerts, Watches and Warnings data is available directly from this JSON file, and previous files of this information are also available.
