The challenge

Official flood warnings are accurate but written for specialists. Residents needed to know what to do and when.

The approach

I turned raw gauge and forecast data into short, actionable messages, delivered by push notification and email, and designed the whole product to meet WCAG AAA contrast and reading-age targets.

The outcome

More than eighteen thousand households have subscribed, and the trust now uses the app as its main channel for severe-weather communication.
