Don't Panic! WeatherAds has the ability to switch your campaign on and off in AdWords or Facebook. This typically occurs when there are no locations that meet the weather criteria, so WeatherAds temporarily makes your AdWords campaign or Facebook ad set inactive (since you cannot have an live campaign with no geo targets).
When the weather changes so that one or more of your micro-locations meet your weather targeting criteria again, then WeatherAds automatically re-activates your AdWords campaign or Facebook ad set.
How to switch your weather adaptive campaign off
To make an AdWords campaign or Facebook ad set with live weather targeting inactive, you must:
First switch off the live weather targeting within WeatherAds
Then pause your ad set within AdWords/ Facebook
