Stormline Weather

Stormline Weather is a fast, focused weather app with no clutter and no ads. The forecast, a moving radar map, lightning strikes and weather alerts are all in one clean view.

KEY WEATHER, ONE CLEAN VIEW
Current conditions, an hourly strip and chart, a 10-day outlook, feels like, wind, UV, humidity, visibility, pressure, sunrise and sunset, and the moon, for where you are or any place you save.

MOVING RADAR MAP
Animated radar for Canada and the United States: recent radar plus a short-term look ahead at where the rain is heading, clearly marked so predictions are never mistaken for what has already fallen.

LIGHTNING STRIKE INFO
Switch on the Lightning layer to see recent strikes on the same map as the radar, and watch them appear as the radar plays.

PUSH NOTIFICATIONS FOR WEATHER ALERTS AND LIGHTNING
Get a notification for severe weather watches and warnings from the U.S. National Weather Service and Environment Canada, and when lightning is detected near your places. Choose which alerts you want. Alerts are off until you turn them on.

AI SUMMARIES
Plain-language summaries of your weather for today, tomorrow and the week ahead, written from your real forecast. Sign in to try free summaries. Stormline Weather Pro unlocks more AI summaries and future AI-powered features as they're added. Summaries are optional and can be hidden in Settings.

HOME SCREEN AND LOCK SCREEN WIDGETS
See the temperature, conditions and what's next without opening the app.

PRIVACY
No advertising and no tracking across other apps or websites. Signing in with Apple is optional and syncs your saved places and preferences between devices; it is also needed for AI summaries and Stormline Weather Pro. The forecast, radar, lightning layer and alerts all work without it. Your location is used to show your local weather and, if you turn them on, to send alerts for your area. You can delete your account and its data at any time from Settings. Details are in our privacy policy.

Forecasts are provided by Apple Weather. Weather alerts come from the U.S. National Weather Service and Environment and Climate Change Canada, and lightning data from NOAA's GOES satellites. Radar contains information licensed under the Data Server End-use Licence of Environment and Climate Change Canada. Stormline Weather is for general information and should not be relied on for emergencies or safety decisions.
