Coastal flooding associated with a combination of high tides and higher-than-normal water levels will be possible through the weekend, the National Weather Service advised Friday. Coastal flooding impacts will be greatest during the peak daily high tide, which happens in Honolulu at 2:51 p.m. today and 3:32 p.m. Sunday.

Water levels at the Honolulu tidal station continue to run about 1 foot higher than predicted, the weather service said. Effects could include flooding of beach areas that are normally dry and saltwater intrusion into typically vulnerable low-lying roads.

Moisture from an old tropical cyclone will increase shower coverage and bring muggy conditions to the islands late today through the first half of next week, the weather service added. Tropical Storm Kenneth, packing 40 mph winds, remains far to the east, closer to Mexico, the National Hurricane Center said.

The work requires helicopter flights from Koko Head District Park, HECO said by email Friday.

The flights are scheduled from 9 to 10:30 a.m. and 2 to 3:30 p.m.

Off-duty police officers will stop hikers from going up the trail while the helicopter is airborne.
