After this past weekend's rough and tumble weather with thunder, lightning, heavy rainfall, and flooding, it's relatively mellow on this holiday Monday morning.

Skies are mostly cloudy, and showers are light to moderate and few in number. With a little luck, conditions will be ideal for the Great Aloha Run.

We still have an unstable atmosphere and heavy showers and thunderstorms are possible again later today. The islands are saturated from the weekend rains, so it won't take much today to create runoff and flooding. Stay alert, stay safe, and stay with your Severe Weather Station.

A trend toward more stable and dry conditions will mean a fairly nice Tuesday and Wednesday this week. Then on Thursday, another stretch of very unstable and wet weather will begin and take us through the weekend.

Surf is building with a new NW swell today, but will stay below advisory levels. We will see a larger NW swell Tuesday night and Wednesday.

Today's waves will be 6-10 feet north, 5-7 feet east, 4-7 feet west, 2 feet or less south.

Flash Flood Watch for all islands through this afternoon.

Wind Advisory for Big Island summits. SW winds will be 35-50 mph with gusts to 60 mph.

Winter Weather Advisory for the Big Island and Haleakala summits. Possible 1" - 2" of accumulation with a chance of thundersnow.
