Please don't be alarmed, tsunami season is long over; this is just O.C. trivia.
Despite the relatively low threat to coastal SoCal, the city of Huntington Beach is so committed to preparedness, that there is a tsunami warning system. This system is tested on the first Friday of each month.
Most locals have heard this sound so many times they tune it out. But every once in a while, I hear someone say something about an alarm...Is it an air raid siren?
If I'm ever in earshot, I simply share the information about the tsunami warning system testing schedule, and they have a bit of trivia they can pass along.
