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.
