Coastal areas may see light wind chop, but contamination from runoff remains the primary concern. Overcast skies and scattered showers make indoor activities or scenic drives the best options.
Kauai's island-wide Brown Water Advisory remains in effect-avoid all ocean activities. While no Kauai-specific news was reported today, a 64-year-old man died in a possible drowning incident in Kona waters (Big Island).
