Santa Ana winds are a well known phenomenon out there but I imagine that strong is fairly rare and notable. Large fires will suck in tremendous amounts of air as the hot air rises up. Those fires are burning a massive area

The fire bombings of cities in WW2 created similar firestorms. I remember a history book describing the winds being strong enough to send bodies tumbling through the streets like leaves.

Very unusual. In the winter and spring Santa Anas are common but that’s more like 20-30 with gusts up to 50. Maybe gusts up to 60 in the canyon areas.

is this, again, that same video that was posted many time on Lemmy like in here :

Here is a screenshot :

I never experienced them when I lived down there for 15 years. But I was in the valley that all the fires currently surround. But yeah that was ages ago. The worst event I experienced was the Northridge earthquake. Global warming is crazy.
