mWater Horizon
Weather
Free · Designed for iPad. Not verified for macOS.
mWater Horizon shows when rivers near the places you care about may flood — and when heavy rain is coming — so you have time to prepare.
Made for communities that live with seasonal floods, Horizon turns global satellite forecasts into a clear, local picture: a live map of river-flood risk for the days ahead, right down to your exact spot.
WHAT YOU CAN DO
• See river-flood risk on a live map — floodplains plus Watch and Warning areas, updated daily
• Check heavy-rain risk on a dedicated rainfall map, with live storm (cloud-top) imagery
• Track the places that matter — home, the farm, family — and check them all at a glance
• Open any place for a 10-day outlook: how likely flooding is, how deep it could get, and the day it peaks
• Get a notification when risk rises at a place you follow
• Use it in your language — English, Français, Português, Español, हिन्दी, বাংলা, Kiswahili, العربية, Tiếng Việt and many more
HOW IT WORKS
Horizon combines satellite flood and rainfall forecasts — including Copernicus Emergency Management Service data — to estimate river-flood and heavy-rain risk almost anywhere, even where there are no local river gauges. It's built to stay fast and clear on a basic phone and a slow connection.
GOOD TO KNOW
• Free to use
• Add as many places as you like
• No account needed to explore the map — sign in only to receive alerts
IMPORTANT
Horizon provides flood-risk information to help you prepare. It is not an official flood warning — only national or regional authorities issue official warnings. Always follow the guidance of your local authorities.
Horizon is made by mWater, a nonprofit working to help people everywhere reach safe water and reliable environmental information.
