Conditions · Rain Radar
See the rain coming.
NOAA's high-resolution radar across the US, looping the last four hours, so you can tell whether that cell is heading your way or sliding past.
Observed, not forecast
The rain that's actually falling
Rain Radar is NOAA's MRMS mosaic from the National Severe Storms Laboratory: every weather radar in the country stitched into one picture, sharp enough to pick single storm cells out of a squall line.
- 1 km detail
- See the edge of the rain, not a blurry blob, and how much clear water sits between you and it.
- A new frame every 10 minutes
- OceanPulse checks for fresh radar every 90 seconds while you're watching.
- Coast to coast
- The contiguous US and the waters around it, out to parts of southern Canada and the Bahamas, plus Alaska, Hawaii, Puerto Rico, and Guam.
Four hours of history
Watch where it's going
Press play and the last four hours run smoothly to now, then loop. Drag through it frame by frame to judge a storm's speed and track before you decide to run for it or wait it out.
- Smooth, not jumpy
- Frames blend into each other as you scrub, with a light tap for each one.
- On your Home screen
- When rain is due near you, a radar card appears on Home. Tap it for the full loop.
- On your chart, too
- Lay the same radar over the nautical chart in Coastal Charts and watch the rain cross the water you're about to.
