Weather Risk Outlook

The Weather Risk Outlook colors are determined after NWS Pendleton meteorologists examine both the impact level of potential weather scenarios AND the associated probability of those scenarios. The resulting outlook displays the highest risk for each day.

NWS Pendleton meteorologists then determine the color by determining the probability of occurrence using all the available information and then reference the matrix to determine the risk level associated with the forecast weather event.
