City Ocean Safety and Lifeguard Services officials plan to assess the box jellyfish situation tomorrow morning before deciding whether to reopen Hanauma Bay, which was closed today at 10:30 a.m. due to numerous reports of people being stung.

More than 15 people were treated for stings within one hour at the popular beach this morning, according to a news release from the Honolulu Emergency Services Department

As of 2:30 p.m. today, three box jellyfish were found at Hanauma Bay.

The numbers were more significant elsewhere: 586 jellyfish found in the Waikiki-to-Ala Moana area and 111 people treated for stings, all but one in Waikiki.

People stung by jellyfish are advised to flush stings with large amounts of white vinegar. Those who experience difficulty breathing, muscle cramps or persistent pain should seek immediate medical attention.
