stormdeck ⛈️ live weather radar, alerts & wind on one map

stormdeck is a free, open-source live weather radar map. It shows real-time United States radar (RainViewer, with NOAA NEXRAD via IEM as fallback), live National Weather Service severe weather alerts, and global NOAA GFS forecasts: temperature, animated wind, precipitation, and thunderstorm potential. All of it moves on one scrubbable timeline.

• Live weather radar with a scrubbable forecast timeline
• Severe weather alerts across the United States (NWS)
• Animated global wind map
• Global temperature and precipitation forecasts (NOAA GFS)
• Storm potential overlay (surface CAPE)

Built with deck.gl and MapLibre over OpenStreetMap, served from near-free-tier AWS. Open source (MIT) on GitHub, by John Carmack. Not an official weather source; for decisions involving life or property, use weather.gov.
