We’re also using AI to forecast floods, another extreme weather pattern exacerbated by climate change. We’ve already helped communities to predict when floods will hit and how deep the waters will get — in 2021, we sent 115 million flood alert notifications to 23 million people over Google Search and Maps, helping save countless lives. Today, we’re sharing that we’re now expanding our coverage to more countries in South America (Brazil and Colombia), Sub-Saharan Africa (Burkina Faso, Cameroon, Chad, Democratic Republic of Congo, Ivory Coast, Ghana, Guinea, Malawi, Nigeria, Sierra Leone, Angola, South Sudan, Namibia, Liberia, and South Africa), and South Asia (Sri Lanka). We’ve used an AI technique called transfer learning to make it work in areas where there’s less data available. We’re also announcing the global launch of Google FloodHub, a new platform that displays when and where floods may occur. We’ll also be bringing this information to Google Search and Maps in the future to help more people to reach safety in flooding situations.
