Disturbance Possible This Weekend
A Small Craft Advisory is posted for waters to the south and west of the Big Island as well as the Alenuihaha channel through 6 a.m. Thursday. East winds up to 25 knots and seas up to 12 feet are expected. Inexperienced mariners should avoid navigating in these conditions.

Breezy trade winds are expected to continue for the next couple of days. Showers will also continue to focus over windward and mauka areas with some sprinkles passing leeward from time to time.
By Friday, weather models are showing a disturbance digging northeast of the islands, with a possible tropical system forming to the southwest as well. The weather models are all showing some type of development but they differ on placement, strength and track at this time. Uncertainty is very high with regard to the precise impact on our weather. Based on the current models, moisture could increase significantly over the islands as early as Saturday and linger into the first part of the week. As we’ve seen throughout hurricane season thus far, a lot can change so I’ll keep an eye on it and bring you the latest.
Today we expect mostly cloudy skies with scattered showers for windward and mauka spots. The Kona side is forecast to be clear in the morning with building clouds and scattered showers in the afternoon. High temperatures from 86° to 91°. East winds are forecast around 15 mph.
