Apple’s Weather app on the iPhone was unavailable to many users on Tuesday. The problems started around midnight ET and continued throughout the morning in many locations. iPhone owners have reported that they opened the Weather app and found no cached data or old weather information.

9to5Mac noted that while the main Weather app was broken for many, the Apple Watch version continued to work fine.

Most of this morning, Support note from Apple said “next hour’s precipitation may not be available to Alaska due to a data provider outage,” despite a problem that was clearly more widespread. It has since been updated to fix an unspecified general persistent issue that affected some users at 11pm last night.

Eventually, the app started to refresh (some of us had to reboot our iPhones or iPads before they could get new weather data), and the Apple System Status page now has a note that says “Issue Resolved” as of about 1:31 p.m. ET .

Apple’s Weather app problems come just a week after Dark Sky briefly returned. Apple acquired Dark Sky in 2020 and shut it down and moved some features to the Weather app. The Dark Sky app returned shortly from the dead last week before disappearing again.

When Apple’s new Weather app works, it has some great improvements thanks to the Dark Sky integration, but many still miss the dedicated Dark Sky app. Apple has added rain alerts, but you can’t control whether you want alerts for light, medium, or heavy rain, which is especially annoying in countries like England where it rains a lot of. Apple is based in California’s Silicon Valley, where it rarely rains, so Apple’s software engineers probably forgot to port that essential feature from Dark Sky.

Update 11:30am ET: Added information about Apple’s new System State error message.

Update 3:51 PM ET: The known issue has been resolved and there is a new status message from Apple.
