SkyGuard Warnings provides proactive weather warnings for specific locations tailored to each customer's needs. It issues warnings when severe weather threatens a customer's facilities up to 24 hours a day, with minimum lead times ranging from 20 minutes to 4 hours depending on the hazard. SkyGuard also issues "Null Warnings" when weather warnings from the National Weather Service do not actually impact a customer's location. The service is now available through an online portal allowing customers to view current weather and customized warnings on an interactive map.
