Eyewall

About

Eyewall watches the places you care about for severe weather: tornado, thunderstorm, flood and tropical warnings from the National Weather Service, today’s storm risk, lightning nearby, storms heading your way, and hurricane forecast cones. When a warning is issued for one of your places, Eyewall tells you within about a minute.

Everything comes from free public data, the same data meteorologists use: the National Weather Service, the National Hurricane Center, the Storm Prediction Center, NEXRAD radar through the Iowa Environmental Mesonet at Iowa State University, and NOAA nowCOAST.

Eyewall is free, with no ads, no account and no tracking.

Features

• Your places: your location and the places you add, each with its warnings, today’s severe risk, lightning nearby and the storms heading for it. They sync between your devices with iCloud.
• Warnings and watches: tornado, severe thunderstorm, flash flood, flood, extreme wind and tropical warnings, with their outlines on the map, when the storm should reach you, hail size, wind gusts and the damage threat. Tornado emergencies, observed tornadoes and particularly dangerous situations stand out.
• Notifications: new warnings at your places the moment NWS issues them, a severe storm or rotation heading for a place, lightning nearby (with an all clear after 30 quiet minutes), a place entering a hurricane’s cone, and a watch that’s likely soon.
• Radar: the last hour of NEXRAD radar, animated, with lightning, infrared satellite, storm tracks and the velocity from the nearest radar. Tap any storm to see its hail, rotation and where it’s going.
• Severe weather: the Storm Prediction Center’s outlooks for today, tomorrow and day 3, today’s storm reports, active watches and mesoscale discussions.
• Hurricanes: active storms with their forecast cones, tracks, model runs, wind chances and arrival times at your places, the advisories, and the areas the National Hurricane Center watches for the next 7 days.
• Everywhere: widgets and Lock Screen widgets, Live Activities for warnings, a menu bar extra on the Mac, an Apple Watch app with complications, and Siri and Shortcuts.
• In English and Spanish.

FAQ

Is Eyewall an official warning service?

No. Eyewall shows public weather data as it’s published, and adds to official warnings; it doesn’t replace them. Keep Emergency Alerts on in your phone’s settings, have more than one way to get warnings, and always follow instructions from local officials.

Where does it work?

In the United States. Warnings and watches cover every state and territory the National Weather Service serves, the radar covers the lower 48 states, and hurricanes are tracked in the Atlantic and the eastern and central Pacific.

How do warnings arrive so fast?

Every minute, a small service of ours reads the National Weather Service’s active warnings and writes the new ones to Eyewall’s public iCloud database. Your devices subscribe to the counties and forecast zones of your places, so iCloud sends a notification as soon as a warning for one of them appears. This needs an iCloud account; without one, Eyewall checks while it’s open, and in the background when the system lets it.

Is Eyewall free?

Yes. There are no ads and nothing to unlock. If Eyewall is useful to you, you can leave a tip in Settings: tips help pay for the service that sends warnings, and for Eyewall’s development.

Why are some alerts in English?

The text of each alert, its description and instructions, is the National Weather Service’s own, and Eyewall shows it as published. Eyewall’s own words and the names of the alerts it knows are in your language.

The translation has a mistake

Eyewall was translated into Spanish with AI, and the app says so in Settings. If something reads wrong, please use Report a problem… there, or write to support@loshadki.app.

Eyewall has no account, no analytics, no ads and no tracking.

Location and places. Eyewall uses your location, when you allow it, and the places you add to ask public weather services for the weather there. It asks them directly: the National Weather Service, the National Hurricane Center and the Storm Prediction Center (NOAA), NOAA nowCOAST, and the Iowa Environmental Mesonet at Iowa State University. A request for a place includes its coordinates or the map area around it, as any weather request for a location does, and these services handle it under their own policies. The maps and the search for places are Apple Maps, under Apple’s privacy policy. Your places are stored on your devices and synced through your own iCloud account; we can’t see them.

Notifications. To send you warnings, Eyewall saves subscriptions in its public iCloud database. Each one names a county or forecast zone of your places (such as “OKC109”) and the kinds of alerts you turned on, not your exact location. iCloud identifies them by an ID specific to Eyewall, not by your name or email, and delivers the notifications. Our service only reads public warnings and writes them to that database; it receives nothing from your devices.

Tips. Apple processes tips. We don’t receive your payment details.
