Tsunami, earthquake, civil unrest (eg H20i), tornado, hurricane etc warning siren heard in the evening. It was followed by 4 sets of fire trucks and ambulances over screaming down coastal highway for the next 20 minutes. Turns out it was a hotel fire. If anyone has any history on where the siren is let me know in the comments. I would guess it is on the water tower but I didnt see anything.
Update: Guess the hotel for bonus points!
