Unstable weather conditions have led to a series of advisories across the Hawaiian Islands, as the National Weather Service (NWS) continues to monitor changing conditions closely. A winter weather advisory for the summits of Hawaii Island remains in effect until 6 a.m. Saturday, with up to two inches of snow anticipated.
Although the flood advisory for Kauai has been canceled, the region experienced significant rainfall, with NWS rain gauges recording 10.6 inches on Mount Waialeale. Other locations also saw substantial precipitation, including 6.7 inches at Poamoho near Wahiawa on Oahu and nearly three inches in Haiku, Maui. Rain is expected to ease statewide tonight into Saturday, although light winds may still cause scattered showers and thunderstorms in interior areas this evening and in windward regions overnight.
Across the islands, moderate tradewinds are forecast to return on Saturday, persisting through the weekend, accompanied by lingering showers. Furthermore, early next week, another storm system is anticipated to disrupt tradewinds and potentially bring heavy rainfall and thunderstorms from Tuesday through Thursday.
Earlier in the day, various flood warnings and advisories were issued and subsequently canceled as conditions evolved. By 4:45 p.m., all flash flood warnings and most advisories had been lifted, with only Kauai remaining under a flood advisory until 6:15 p.m. Heavy rainfall was reported, particularly south of Mount Waialeale, with rates of one to three inches per hour.
In Oahu, the flash flood warning and flood advisory were canceled as conditions improved, though Maui remained under a flash flood warning until 4:30 p.m. and a flood advisory until 6:30 p.m. Meanwhile, as of 1:35 p.m., a flash flood warning was in effect for Maui until 4:30 p.m., with emergency management reporting heavy rain over Haleakala’s slopes and summit.
At 1:15 p.m., West Oahu was under a flash flood warning until 3 p.m., with heavy rain observed over Waianae Valley. The warning encompassed numerous areas, with rainfall rates between one to three inches per hour. The NWS also issued a special weather statement regarding a strong thunderstorm affecting the region, with potential wind gusts up to 40 mph and pea-sized hail.
Earlier advisories included a flood advisory for Maui, Molokai, and Oahu. At noon, heavy rain was reported over West Maui Mountains and Haleakala’s slopes. The advisories were extended as conditions persisted, with radar indicating rainfall on the west side of Oahu and eastern Molokai.
In the morning, Kauai was under a flash flood warning due to heavy rains, while weather officials cautioned against crossing fast-moving water. The weekend forecast anticipates continued showers, particularly in island interiors and windward areas, with the possibility of thunderstorms as an upper low moves across the state. The NWS also foresees another storm system potentially impacting the islands early next week, bringing more heavy rain and thunderstorms.
