Heavy rains pounded parts of Oahu including the Windward side. 

Heavy rains typically cause storm water runoff to enter coastal waters, causing it to get that murky brown color.

The public is advised to stay out of flood waters and storm water runoff for safety reasons.

Thursday morning's heavy downpour also closed both directions of Kamehameha Highway between Waikane Valley Road and Waiahole Valley Road just after 9:30 a.m. due to flooding near the bridges. 

The road was reopened but the closure backed up traffic for about an hour

"It was raining really hard in the morning. You would say like cats and dogs... The ground was really saturated and then big rain came and it comes from the mountain and flows down the stream," Nadine Tokuzato, owner of Waikane Store, said.  

Resident and businesses in that area say it's common for flooding to happen in that area because the stream overflows when its downpours in that area.

Down the coast, not too many people out in the water today as Ocean Safety advised the public to avoid murky waters, adding that there is and increased risk of shark attacks after heavy rains.
