Lifeguards had not reported any stings this morning, and the jellyfish have been sighted only at Kuhio Beach so far, a spokesman said.

However, the periodic appearances of the jellyfish commonly affect Ala Moana, Hanauma, Poka'i Bay and Makaha beaches.

Anyone who suffers a box jellyfish sting is advised to flush the area with white vinegar. Those who experience difficulty breathing, cramps, spasms or persistent pain are urged to seek medical attention. Lifeguard stations are equipped to provide first aid.

For details on similar advisories, a recorded report is available at 922-3888, extension 51.
