How to use this page:

This page is especially developed for users in Alaska. Because HDW is designed to work during daylight hours, the Alaska CFSR climatology uses the maximum HDW from 1800, 0000, and 0600 UTC for a given day, while the GEFS forecasts use 1800, 2100, 0000, 0300, 0600, and 0900 GEFS output. All other functionality should be the same as the main HDW page.
