📢 Why is it free?
To help keep the lights on, we include a few sponsor messages:
Mercury Falling includes occasional weather-relevant sponsor messages. No user data is collected or used to target these messages. Use of this service is intended for users 13 and up.
About half the time, alerts include a link to a helpful product like frost covers, pet gear, or pipe insulation.
Once a month, you’ll get a seasonal tip from us referring a local service provider (like a plumber or HVAC tech), based on your ZIP code and recent weather.
We never share your data. If you’re interested in the service, you reach out. If not, ignore it.
