Shark warning signs will remain in place this morning but will be taken down at noon today at west-side city beaches from Nanakuli to Makaha, said Bryan Cheplic, spokesman for the city Emergency Services Department.

The signs went up yesterday after a woman was bitten on the forearm by what may have been a tiger shark at a beach near Mount Lahilahi in Makaha.

The woman was taken to The Queen's Medical Center and is recovering.

No sharks were spotted during an assessment of the beaches done about 6:30 this morning, Cheplic said. Nonetheless, the signs will remained in place, until Honolulu Fire Department and Coast Guard helicopters did a flyover of the affected beaches and found no sign of sharks,Cheplic said.

In addition to the potential chark problem, beach-goers should be aware that the box jellyfish may begin their monthly influx in waters along south shore beaches as early as today, Cheplic said.

"We're asking people to check with the lifeguard before going into the water," Cheplic said.
