See risk before it happens
Beyond the official alerts, CyWarn works out where the next danger is building — for wildfires, water and more — and tells you why, in plain language.
It's here to help you decide, not to replace judgement — and it always shows how sure it is.
How it works, in four steps
From official data to a clear answer on your phone — around the clock.
What CyWarn calculates
Four things it works out for you — each explained the moment it matters.
Wildfire risk
For every part of the island, CyWarn works out how likely a fire is to start today — from the heat, the wind and how dry it has been.
Water-shortage outlook
It projects how the island's reservoirs will develop over the coming weeks — so a shortage is visible long before it bites.
Fire spread
If a fire starts, CyWarn shows where it could move next — following the wind, the slope and the vegetation.
The right alerts first
It sorts incoming warnings by what actually affects you — your area and the type of danger — so nothing important gets buried.
No black box
Every estimate comes with the reasons behind it and how confident CyWarn is. You always see why something is flagged — never just a number you have to trust blindly.
