The first full amplitude wave is in at about 1.8 feet. So far the forecast for Adak of 1.3- 2.5 ft rise is holding.

The 2nd wave peak is in and it is a little smaller than the first after accounting for tide. It's good to see it is not worse than the first!

NTWC official prediction is 1.2- 2.2 ft for Adak. This is just the first wave. Will see if later waves are bigger.
