Tsunami Warning System

Does San Diego have them?

Yes, we do. They are posted at the beaches and along the bays. As mentioned, they are very useful. "Get yo' butt away from the water!"

Luckily, for most of our area, there are hills very close to the beaches and bays. Walk 15 minutes and you won't get swept away. However, some areas are very dangerous with no high ground close by.
