See when a storm will reach your town.
Sky Sense™ tracks a storm as it moves and tells you when it will get to you. A heavy storm 6 miles to the east is moving west at 25 mph, and its track puts it near Nogales by 5:14 PM. It also shows the real chance of a tornado, hail, or strong wind straight from the data.
- Arrival times for your town.
- The real details: storm strength · rotation · speed.
- Written in plain language to read quickly.
A dangerous cell looks as strong as it is.
The radar shows storms at full color intensity, so they present accurately on screen. The full radar suite for Plus subscribers adds professional radar layers that give you the same deep level views as meteorologists.
- Reflectivity for everyone. Velocity · echo tops · VIL and dual-polarization come with Plus in the US.
- Overlays for satellite · lightning · severe warnings · storm tracks.
- Play back the last hour to see where a storm is going.
Follow a named storm night or day.
