Coastal flood early warning
Know before the water rises.
Flood-Cast watches the conditions that drive real coastal flooding on the Florida coast — spring tides, king tides, and hurricanes tracking just offshore — and turns them into one clear risk number, from all clear to Flood Now.

Wonβt cry wolf
A full alert only fires when conditions truly line up — so when Flood-Cast speaks up, you listen.
The four conditions that drive a flood.
Flood-Cast is tuned to the combination that put water in homes during Hurricane Helene. It only raises a full alert when the conditions stack up — and shows you each one building in real time.
