Forewarn

Forewarn tells people in Africa what the next rain will do to their own street, farm or village, days before it comes. For most people on the continent, the flood warning is still the water itself. In Mathare, Nairobi, on the night of 23 April 2024, people woke to their neighbours shouting "Maji! Maji!" as the river came into their homes. Put a pin on your door and type your question, or ask it out loud in English, French or Swahili. Forewarn reads 51 runs of the ECMWF forecast for the next 14 days and the last 30 days of rain. It answers with a level (unlikely, possible or likely) and the chance in words, such as "about 1 in 4 forecasts". In Lagos and Nairobi it plays the last big flood on your street over the satellite map, hour by hour. Send a photo of the water, and it marks the water, says what it reaches and pixelates the people. Follow an area by email. An agent checks it every 6 hours and drafts an alert when a flood looks possible. A person approves every alert before it goes out. Pass a warning on through WhatsApp as text, an image card, or a voice note in Swahili, Yoruba or Hausa. We replayed 36 African floods since April 2024 with today's rules. Forewarn flagged 29 of them in advance, 28 of those 3 days or more ahead. It flagged the Nairobi flood of 23 April 2024 7 days before the water came. Live and free, no account: https://forewarn.site
