A F0 tornado, which began as a water spout, hit Long Beach, CA, in 1998. I remember it because it hit the roof of the grocery store across the street from my doctor’s office, where I had an appointment about 15 minutes after it struck.
It ripped off a pretty significant section of the grocery store’s roof (remember, California building codes are pretty stringent due to earthquakes) and it must have passed over the neighborhood high school just seconds before hitting the store. It then moved north northwest, ripping up some of the trees that are behind the house we currently live in, skipping over the houses and then ripping up some of the trees outside the middle school across the major street outside our front door. The scary thing was the time of day; it was after 2 p.m. and kids were heading home from both the high and middle schools and no warning or indicators. There are photos of my immediate neighborhood that show the fallen trees.
I’d rather deal with the rare earthquakes rather than the seasonal tornados.
