Get Weather Alerts
The basic Apple Watch weather app lets you check to see the weather for your day, but you can supercharge this with Dark Sky.
This paid iPhone app allows you to get notifications before it is going to rain or snow. You can get an alert up to 15 minutes before rain arrives which is perfect for people with kids or dogs.
I use it to know when to take dogs out before a thunderstorm or heavy rain. Several parents we know use it to get alerts when it is going to rain if their kid is outside playing.
Download Dark Sky on your iPhone and make sure it is on your watch and set up for notifications.
