Hawaii – Northwest HI & Waimea Bay Buoys Building

Solid long-period forerunners began to show at midnight last night (5.6 feet at 19 seconds) on the Northwest Hawaii buoy, which is currently 10.5 feet at 17.4 seconds.

The Waimea Bay buoy is starting to creep upwards, and is currently 2.6 feet at 18.2 seconds. Look for the swell to continue to build through tonight.
