Radar & Satellite
Radar and satellite, live.
Radar every 2 minutes, satellite every 10. Zoom anywhere in the Lower 48; add the clouds under the radar.
Our forecast swaps the radar for the WeatherQB forecast: today's and the next two days' high, rain (8 AM to 8 AM Eastern) or peak gusts, the same numbers as the Hazards maps. Tap anywhere for the number at that spot. Contains modified ECMWF data.
Rain and snow (in blue) falling now, every 2 minutes, with the National Weather Service's warnings outlined. Tap anywhere for that spot's forecast, or inside a warning for what it is and when it ends.
How to read this map
- Warnings: tornado (red), severe thunderstorm (yellow) and flash flood (green) warnings, solid; watches dashed. Checked every minute.
- Storm risk: today's severe storm risk areas, dotted.
- Clouds: the clouds from satellite under the radar, clear sky see-through, matched to the radar's time within 10 minutes.
- Rain totals: how much fell in the last 1, 6 or 24 hours, melted snow included. The 6- and 24-hour totals are corrected with rain gauges and run about an hour behind; the last hour is the radar's own estimate, current to the minute, which can run high or low, especially in the mountains and near the edge of a radar's reach.
- Flood watches and today's excessive rainfall risk are named under the map rather than drawn, since their colours would read as rain.
- Map: Light, Relief (terrain) or Dark underneath.
