The state Health Department issued multiple brown water advisories across Hawaii Monday due to heavy rains.

>> On Oahu, a brown water advisory was issued for Kailua Beach Park and Kaneohe Bay, as well as Oahu’s North Shore, from the shores of Kaena Point to Kahuku to Kaaawa.

>> On Hawaii island, a brown water advisory wasvissued covering waters from Holoholokai Beach Park to Pololu Valley, as well as at HIlo Bay and along the Hamakua coast.

>> On Kauai, a brown water advisory remains in effect at Koloa Landing.

“Heavy rain has resulted in stormwater runoff entering into coastal waters,” said department officials. “The public is advised to stay out of flood waters and storm water runoff due to possible overflowing cesspools, sewer, manholes, pesticides, animal fecal matter, dead animals, pathogens, chemicals, and associated flood debris.”

While not all coastal areas may be impacted by runoff, officials recommend staying out of the water if it is brown.

The state Health Department recommends people “continue to practice good personal hygiene and follow-up with your primary care physician if you have any health concerns.”
