Skies over Daniel K. Inouye International Airport are mostly cloudy this afternoon, with a few isolated morning showers giving way to mostly sunny conditions and a high near 82°F. East winds along the shoreline are expected to stay breezy around 10–12 mph, before temperatures dip to a low near 71°F overnight. By Tuesday, though, a low northwest of the islands will start tugging deep tropical moisture northward, setting up a much wetter pattern later in the week with a growing risk of heavy, widespread rain and localized flooding.
Today's Forecast
Isolated showers may linger before noon, but most spots can expect a dry, mostly sunny afternoon with highs near 82°F and easterly winds around 10–12 mph. Windward and mauka areas still have the best shot at those quick passing showers, while downtown and leeward neighborhoods should trend noticeably drier, according to an earlier forecast breakdown.
Midweek Flood Risk
A Hydrologic Outlook is in effect as forecasters eye Wednesday night into Thursday night for the most likely window of steady, widespread rain. Some storms could drop heavy downpours capable of triggering localized flash flooding, and the unsettled pattern may hang around into the weekend. "Now would be a good time to clear storm drains, culverts, and other drainage areas of debris to help reduce localized flooding," the agency advises, with updates available from the National Weather Service.
Marine Outlook And Surf
Overlapping north and south swells are set to build both shorelines late Tuesday into Wednesday. As southerly winds strengthen later in the week, expect choppier seas and rougher conditions, with south-shore surf possibly pushing toward advisory levels. Small craft operators and paddlers should plan for bumpy, gusty outings and think twice before heading too far offshore as conditions deteriorate.
What To Do
On land, now is the time to clear gutters and storm drains, secure outdoor furniture, and move vehicles away from low-lying spots where water tends to collect. Avoid driving through standing water, respect any barricades or closures, and give yourself extra time if you have to be on the roads. Keep phones charged, have a backup plan for outdoor events from Wednesday on, and stay tuned to local officials for any watches or warnings.
