The National Weather Service has extended its advisory regarding high tides and possible coastal flooding through Wednesday as an eddy moving through the islands raises sea levels.

Water levels are running as much as a foot above the values shown by tide predictions, the weather service said.

Peak water levels will occur during the afternoons and evenings through Wednesday. High tides in Honolulu will occur at 3:32 p.m. today, 4:10 p.m. Monday, 4:48 p.m. Tuesday and 5:24 p.m. Wednesday.

That could result in waves over beach areas that are normally dry and seawater covering coastal roads.

Tropical moisture from the east will bring an increase in shower coverage and muggy conditions through Tuesday, the weather service said.

Meanwhile, Tropical Storm Kenneth in the eastern Pacific had grown in strength, packing sustained winds of 70 mph — just below hurricane strength — as of Saturday. It was forecast to become a hurricane today, but then turn north and weaken, becoming a tropical storm again by 5 p.m. Tuesday.

It was moving west at 17 mph Saturday, but was still 1,970 miles east-southeast of Hilo as of 5 p.m. Saturday.
