Functionality

Locations can be added or removed by pressing the list icon in the bottom right corner of the application, which allows the user to type in the city's name, ZIP Code or postal code or airport code. For each city, the app will display the current, highest, and lowest temperatures, a 10-day forecast, UV index, time of sunrise and sunset, current wind direction and speed, rainfall measurements, current humidity, outdoor visibility range, and barometric pressure. In some locations, the app will also display an air quality report and show next-hour precipitation when raining or snowing. iOS 14 introduced support for severe weather warnings, allowing a user to receive notifications for government-issued severe weather events such as tornadoes, flash flooding, strong winds, and snow storms.
