As Hurricane Hector approaches, the best would be for it to keep pushing south. The worst, could be the timing. The storm comes just as experts are predicting  'King Tides.'

"We always hope for the best, but plan for the worst," Mayor Kirk Caldwell said. "If you see high tides and a storm surge, you're going to see flooding." 

According to researchers from the University of Hawaii, 'King Tides' were already expected to roll in this Thursday and Friday.

"We can say that Hurricane Hector may exacerbate the high water levels that we're already expecting," Maya Walton, program leader of the UH Sea Grant College Program said. 

Meteorologist with the Central Pacific Hurricane Center say the surf from Hector could build up the tides even higher and increase coastal flooding. Especially for areas prone to floods, like Mapunapuna and Waikiki. 

"These tides aren't really directional, they can affect any side of the island so areas that typically do see problems those would be areas of concern as the east facing shores where we see a little of surf action from the Hurricane Hector swell," director for Central Pacific Hurricane Center, Chris Brenchley said. 

The City and County of Honolulu has already begun preparing for the worst case scenario by clearing the mouths of streams, putting up sandbags and now urging residents to do their part. 

"With the high surf, it could compound that flooding so we're asking people in low lying areas to be prepared, plan ahead, maybe put up sandbags," Caldwell said. 

King Tides are expected to peak on Thursday at 3:05 p.m, in waters off Honolulu. Researchers at the University of Hawaii say it's too soon to tell how much the tides will increase, but they also predict it'll be higher expected. 

"We'll really have to go out and take photographs and report observations," Walton added.

Walton says to consider safety first, but if you are along the coastline and can snap a photo, submit it to the Hawaii and Pacific Islands King Tides Project at:
