Behind the powerful jet that brought back to back storms through southern California, upper level high pressure built back in over the eastern Pacific, resulting in strong northerly (offshore) flow over the region on the mornings of the 27th and 28th. The typical canyon/pass areas and Inland Empire received the strongest winds, both sustained and gusts. Many stations reported sustained winds over 40 mph along with several gusts over 60 mph. Despite the strong gusts and sustained winds, only a few damage reports came in regarding power poles and containers blown off of a semi truck.
