The Tsunami Warning Center was on this all last night. They sounded the warning sirens this morning (6 AM & 7 AM) to get people moving up. There was another siren at 11 AM as a reminder that it was showtime. The evacuation has been carried out and the whole state is locked down.
Hilo Bay & the park (which used to be bustling waterfront until the 1960 tsunami) seems pretty calm. There's a definite surge but thankfully it's less than forecast. We've seen a couple cycles now and it doesn't seem to be getting any worse.
I've never seen so many live beach cameras... if we get through this without damage, the Hawaii Visitors & Conventions Bureau is going to be turning backflips over all the free coverage. Streets, malls, parks, everything is closed. I think everyone is hunkered down somewhere with a camera feed.
Sailboats have been ordered to sea. Most marinas on Oahu require all their sailboat tenants to actually drive outside the breakwater once a year before they're allowed to sign a lease, so everyone's expected to be seaworthy for a mile past the breakwater.
We heard that Pearl Harbor sortied four warships but no details. If it's a busy weekend then it's possible that's everyone who was inport but I don't know for sure. Haven't heard whether or not submarines were required to sortie.
I can't ever recall a traffic mess up there. I think this is going to be the best-executed (and best-covered) tsunami in history.
