Weather apps are the most downloaded category of apps in any app store. People seem to be obsessed with them.

Apple delivered a ton of "hidden" improvements in iOS15 that you probably won't be able to find on your own. One such improvement is the ability to receive real-time precipitation alerts through Apple's iOS weather app.

In order to enable this new functionality:

• Open the weather app.

• Tap the icon with three dots on the lower right corner of the screen

• Click on the 3 dots in the upper right corner of the screen

• Select Notification

Turn on the toggle next to the locations you want alerts for.
