RadarCast zoomed to street level over Columbus, Ohio — showing individual roads and the Columbus Zoo inside a super-resolution reflectivity field.

Pro-grade NEXRAD radar

Level II data rendered with trapezoid-per-gate precision across 157 radar sites. Zoom past the clouds to individual streets and structures — the same detail meteorologists rely on, in your pocket.

Real-time lightning

Every flash from the GOES-19 satellite, coast to coast, updated every minute. Watch cells electrify before they reach you, with storm tracks, warnings, and NWS alerts all on the same map.
