Kauai's entire coastline is under a brown water advisory, bad news for swimmers, surfers, and anyone with ocean plans this week.

• The state health department told people to stay out of the ocean around the whole island.
• Storm runoff is washing sewage, bacteria, and chemicals into coastal water.
• Anywhere the water looks brown or murky should be avoided, not just posted beaches.
• Contact with polluted water can cause infections and illness.

Outlook: The advisory stays in place until runoff clears and the water tests clean again.
