The National Weather Service in Honolulu has issued a “Special Weather Statement” for “Coastal Flooding” for the County of Maui. This includes Lanai, Molokai, and Maui.
Coastal flooding associated with King tides will be a possibility the next couple of days. The greatest potential for coastal flooding impacts will be during the midday over the next couple of days, and in the mid to late afternoon hours Friday into early next week. Visit tidesandcurrents.noaa.gov for more specific information about forecast tides and water levels in your area.
Impacts of the King tides may include flooding of beaches that are normally dry, salt water inundation of typically vulnerable low-lying roads, docks, boat ramps and other coastal infrastructure. The potential for coastal flooding will diminish early next week as the peak daily tides diminish.
Coastal flooding can happen without advanced notice. Please check with local public safety officials prior to heading to the beach or stream mouths. The County also advises you that: “If IN DOUBT, DO NOT GO OUT!”
Help us document the king tides by taking photos and entering them into our database. Every photo that is entered into our database provides information about how future changes in sea level may impact our coastal areas (and some areas more than others). This will ultimately help to plan and prepare.
You can enter photos into our database manually or using the phone app. Either way, it is best spend a few minutes setting up and logging in before the event, so you can be ready.
