A Flash Flood Watch is posted for all islands through the day Friday due to the threat of heavy rain and saturated grounds across the state. Thunderstorms are also possible.
A High Surf Warning is posted for east facing shores of the Big Island through 6 p.m. Saturday with wave heights rising to 12 to 18 foot faces in some spots Tuesday. Expect ocean water occasionally sweeping across portions of beaches, very strong breaking waves and strong longshore and rip currents. Breaking waves may occasionally impact harbors making navigating the harbor channel difficult. Large breaking surf, significant shore break and dangerous currents will make entering the water very hazardous. Boaters should be aware of an increased number of surfers in the water.
A High Surf Advisory is posted for south facing shores from 6:00 a.m. Friday through 6:00 p.m. Saturday. Expect strong breaking waves, shore break and strong longshore and rip currents making swimming difficult and dangerous.
A Small Craft Advisory is posted for Big Island windward and southeastern waters as well as Alenuihaha channel through 6 p.m. Friday for rough seas up to 13 feet. Inexperienced mariners should avoid navigating in these conditions.

Looking Ahead
A humid and unstable air mass continues to linger so locally heavy showers and thunderstorms are possible through at least Friday and possibly even into the weekend. Winds are forecasted to remain light and humidity will continue to be high. Hurricane Jimena moves to the northeast of the state next week, and may begin to drift closer to the islands late next week. The system is still too far out to determine what if any affects may result.
