Tsunami Warning Board Screensaver
The Tsunami Warning Board screensaver shows real active US tsunami alerts. It is free, runs in your browser, and ESC exits.
How the Tsunami Warning Board screensaver works
The saver reads real active alerts from the National Weather Service API.
Each entry shows a real event type, affected area and time sent.
The board shows an all-clear state when no real alert is active.
No key is required for this key-less public endpoint.
A worked example
When a real coastal tsunami advisory is active, its real headline and affected area appear on the board.
Settings & tips
- Event types and areas are real, unedited National Weather Service alerts.
- Accent recolours the board and header text.
- Tsunami alerts are genuinely rare, so an all-clear state is normal.
