Yahoo has rolled out a redesigned version of its Weather app, and it’s available now for iOS users in Canada and worldwide. The app says weather data is from AccuWeather. The new Yahoo Weather app is available to download now on the App Store. If you’re a weather app junkie this looks like a nice update. Back in 2013, the Yahoo Weather app received an Apple Design Award at WWDC, the same year it expanded the app to the iPad.
