I made it down to the harbor at a few minutes after 11. All of the gas stations on the way in and out of town are quite busy. The harbor wasn't busy when I arrived, but by 11:15 it was getting real busy, with lots of trucks pulling in as I left.
They're predicting a 2 meter rise in sea level here in the Kailua-Kona area, which makes keeping your boat in the boat park kind of dicey. The shop is about a half mile inland and a bit uphill, maybe 40-50 foot elevation, and is out of the predicted tsunami inundation zone.
I'll probably move things further uphill about 2 o'clock. They just announced the latest predicted time to be around 3:45 to 3:50am.
