When it matters

Warnings take over the screen.

Your home screen goes red while a warning is active. Whether it's a Tornado Warning or a Flash Flood Emergency, the official guidance is explained in easy to follow steps. When enabled, the alerts are sent out for your current and saved locations. The current location alerts are always free for everyone.

Sky Sense™

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.

Radar

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.
Tropical

Follow a named storm night or day.

When a tropical system forms, SkyMochi tracks it in full. The official forecast path marks the storm's position for each day. You also get its current strength and top wind speed plus the latest forecast discussion. It all plays over a live satellite view with rain radar right on the storm.

  • The official forecast cone with each day's spot along the track.
  • Live strength and top wind speed as the storm changes.
  • The season's formation outlook and the latest forecast discussion.
