Western Weather Mobile Alert Monitoring System

The Sonoma County Winegrape Commission and Western Weather Group have teamed up to provide a new Mobile Alert Monitoring Service that allows you to receive alerts based on weather parameters observed by automated weather stations in Sonoma County. The user selects the station(s) and sets the alert parameter(s) on a password protected web page.  Alerts are sent via email and/or text message and can be sent to multiple people within your organization.  Near-real time data from the automated weather stations can be viewed on your Smart Phone or PC

Frost Protection: Weather alerts can keep growers apprised of critical changes in the weather during the frost season. Growers receive e-mail or text messages to their cell phones when alarm setting are triggered. This service is ideal if you need to know when the temperature reached 36°F, the winds are over 5 mph or dew points are below 32F. Alarms reset after 8 hours, therefore multiple alarm setting are required to follow changes throughout the night, e.g. temperatures at 36F, 34F and 32F. Set alarms for the Sonoma County weather station nearby your vineyard.
