Honolulu is starting Saturday with light rain, but the bigger concern is still building: Tropical Storm Lala is expected to bring tropical-storm-force winds, flooding rain and dangerous surf to Oahu from Saturday evening into Sunday. The forecast calls for a high near 86 and a low near 77, with conditions turning considerably rougher after sunset.
Winds Strengthen Saturday Night
Rain showers are likely Saturday, with northeast winds of 23 to 28 mph and gusts up to 39 mph. A tropical storm warning remains in effect for Honolulu, with the local forecast calling for winds of 35 to 45 mph and gusts potentially reaching 60 mph from early Saturday evening through Sunday morning, according to the National Weather Service Honolulu office.
Flood Risk Rises After Sunset
Saturday night brings a 90% chance of showers, cloudy skies and 1 to 2 inches of new rain possible. A Flood Watch is in effect for Oahu from Saturday evening through late Sunday night, with 4 to 6 inches of rain forecast and isolated totals up to 8 inches possible; low-lying roads, poor-drainage areas and streams could become hazardous.
Sunday Could Bring Thunderstorms
Sunday's forecast keeps the high near 86, but calls for an 80% chance of showers and thunderstorms, some capable of producing heavy rain. Winds may range from 13 to 26 mph, while the low settles near 77 Sunday night as showers become more scattered.
Surf And Outdoor Plans Take A Hit
Large swells are expected to build along exposed east and southeast shores, with dangerous surf, beach erosion and overwash possible. Anyone heading to the coast should stay away from rough water and keep clear of shore roads or other low-lying areas where flooding can develop quickly.
Conditions Ease Monday
The forecast begins to settle Monday, with scattered showers, partly sunny skies and a high near 86. Rain chances drop to 30%, then fall below 10% Tuesday and Wednesday as east-northeast trade winds return, although the week remains breezy and occasionally cloudy.
