Technically it's not a Santa Ana Wind event... different dynamic involved here... strong NW wind flow typical of this time of year but it becomes a katabatic wind when it reaches the western-most Transverse Range known as the Santa Ynez Mountains. However the same dynamic is creating similar conditions as the same winds interact with the Topatopa, San Emigdio, Santa Susana, and western San Gabriel Mountains and even the eastern end of the Hollywood Hills. However, technically and by definition the word "Sundowner" only applies to this effect as it pertains to the Santa Ynez Mountains of Santa Barbara and Ventura Counties.

It's been quite windy here in Northridge for a few hours. Do not ever recall having a Santa Ana in the end of June.
