iOS 15 Severe Weather Alert Updates Explained

With the release of iOS 15, Apple significantly overhauled its native Weather app, introducing real-time push notifications for severe weather events and next-hour precipitation. By integrating data and technology from Apple's acquisition of Dark Sky, iOS 15 delivers timely, government-issued alerts directly to the lock screen so users can prepare for hazardous conditions. This article outlines the specific changes Apple introduced to severe weather notifications in iOS 15, how the system operates, and how to manage the settings.

Government-Issued Severe Weather Alerts

Prior to iOS 15, the native Weather app lacked native push notification capabilities for dangerous conditions, requiring users to rely on third-party apps for alerts. In iOS 15, Apple integrated official severe weather notifications issued by local meteorological agencies, such as the National Weather Service in the United States. Users can receive immediate push notifications for critical events, including:

  • Tornado warnings and watches
  • Flash flood and flood warnings
  • Severe thunderstorms
  • Winter storms and blizzard conditions
  • Extreme heat advisories
  • Hurricane and tropical storm alerts
  • High wind advisories

When an alert is active, it also appears as a prominent, color-coded banner at the very top of the Weather app's main view, providing detailed information about the severity, affected areas, and expiration time.

Next-Hour Precipitation Alerts

Alongside general severe warnings, iOS 15 introduced minute-by-minute precipitation alerts. Using localized radar tracking, the system alerts users when rain, snow, sleet, or hail is about to start or stop within the next hour. This feature initially launched in supported regions including the United States, the United Kingdom, and Ireland.

Granular Location Controls

iOS 15 introduced individualized notification controls within the Weather app. Instead of a single system-wide toggle, users can customize alerts based on specific locations:

  • Current Location: Users can enable severe weather and precipitation alerts for their dynamic location, allowing alerts to update as they travel. This requires setting Location Services for the Weather app to "Always."
  • Saved Locations: Users can selectively toggle severe weather notifications on or off for individual cities saved in their Weather list, making it possible to monitor conditions for family members or frequent travel destinations.

How the Notifications Are Enabled

Apple placed the notification settings directly inside the Weather app interface rather than strictly within the iOS Settings app. To configure these alerts:

  1. Open the Weather app.
  2. Tap the List icon in the bottom-right corner.
  3. Tap the More icon (three dots) in the top-right corner.
  4. Select Notifications.
  5. Grant notification permissions if prompted, then toggle on Severe Weather for "My Location" or any individual saved city.
