Weather app
I have an iPhone 13 pro max. It’s raining outside but my weather app doesn’t show it. I checked the display and it’s on standard. What do I do now?

Use the Weather app 
to check the weather for your current location or in other places. You can view the upcoming hourly and 10-day forecast, see severe weather information, view weather maps, receive precipitation notifications, and more.
Note: Weather uses Location Services to get the forecast for your current location. To turn on Location Services, go to Settings 
> Privacy > Location Services > Weather, then choose an option. Turn on Precise Location to increase the accuracy of the forecast in your current location.
