- Not enough rain - the rain needs to be heavy enough and fall for long enough to trigger an alert. For example a 1 minute light shower probably won't trigger an alert.
- Continuing rain - if there has only been a short period of dry weather between rain falling then we won't send another alert.
- Uncertainty - if we are not sure that it will rain then we won't send an alert.
- Difficult conditions - predicting the rain can be very tricky, so there are times when we just don't get it right. We are constantly working on our algorithms to make sure this a rare event.
If you are finding that the app is consistently having issues predicting the rain in your area please let us know so we can improve our systems.
