Hawaii Ocean Safety officials posted signs at beaches around Oahu on Thursday morning as large numbers of box jellyfish continued to wash ashore.
Signs were posted at a number of locations in Waikiki, including Duke Kahanamoku Beach Park, Kapiolani Beach Park, Kuhio Beach Park and Sans Souci Beach Park, as well as on the North Shore at Sunset Beach and Waimea Bay.
As of approximately 9:00 a.m., 30 box jellyfish had been collected in Waikiki, with 50 additional jellyfish collected at both Sunset Beach Park and Waimea Bay Beach Park.
No jellyfish were collected at Ala Moana or Hanauma Bay.
Box jellyfish are difficult to see in the water, and the signs are designed to warn beachgoers of the risks of swimming in waters with large number of jellyfish present.
If you are stung, Ocean Safety officials say to "flush the affected area with copious amounts of white vinegar and use heat or cold for pain." Anyone experiencing difficulty breathing should seek immediate medical attention.
