FlashNet

FlashNet predicts thunderstorms and lightning up to 3 hours ahead, before the first strike hits. Most weather apps tell you it's raining once it's already raining. FlashNet is different. Powered by AI and next-generation satellite imagery from the MTG Lightning Imager, it detects the early signals of convective activity and gives you a 3-hour window to act. What FlashNet does: Forecasts thunderstorm development and lightning activity up to 3 hours in advance Updates every 10 minutes at 1 km resolution across Europe Displays live and predicted lightning on an interactive map Works entirely from space, no reliance on ground-based sensors alone Built on next-generation satellite data FlashNet uses imagery from Meteosat Third Generation (MTG), Europe's most advanced weather satellite. Its Lightning Imager detects both cloud-to-ground and intra-cloud lightning, the kind that precedes storms before they fully develop. This gives FlashNet an earlier warning signal than traditional lightning networks. AI-powered, probabilistic forecasting Under the hood, FlashNet runs a deep learning model trained on years of satellite and radar data. Rather than producing a single deterministic forecast, it understands storm uncertainty, giving you a more honest picture of where and when conditions are dangerous. Who uses FlashNet: Whether you're a weather enthusiast tracking storm cells, a hiker planning a mountain route, or just someone who doesn't want to get caught in a hailstorm, FlashNet gives you the lead time to make smarter decisions. FlashNet is free to use. Developed by MeteoLibre, an AI weather startup based in Toulouse, France.
