Weather Alert in Oahu
WEATHER ALERT: Reposting from Stolen Stuff Hawaii NWS Hawaii Weather Radar Loop – 4:10PM HST – 4/9/2026 NEW STORM SYSTEM IMPACTING STATE – HEAVY RAIN AND FLOOD RISK RETURNING A new storm system is actively impacting parts of the state, with radar showing widespread moisture across the Big Island and developing rain bands west of the islands that will continue moving in. While Oʻahu and Kauaʻi are currently seeing lighter conditions, this remains a developing situation and additional rain bands are expected to rotate through. This system is being driven by a low pressure area northwest of the islands, pulling in deep tropical moisture. Forecast guidance indicates this will not be a quick passing event, but a multi-day pattern with periods of showers and pockets of heavier rain through the next several days. Currently, the Big Island is seeing the most active weather, especially around Hilo and windward areas where moderate to heavy showers are ongoing. Maui County is beginning to see increasing moisture, with additional rain bands expected to build west toward Oʻahu as the system evolves. The biggest concern continues to be flood potential. Even though rainfall may come in waves rather than nonstop, the atmosphere remains very moist and unstable. Repeated rounds of rain could lead to localized flooding, especially in areas that receive heavier bands or thunderstorms. Oʻahu remains vulnerable despite the current lull. Ground conditions are still recovering from recent storms, meaning it will take less rainfall to trigger runoff and flooding. Areas like Manoa, Waikiki, and previously impacted zones should continue to be monitored closely. Looking ahead, expect unsettled weather statewide through the next few days with passing showers and occasional heavier bursts as moisture continues to move through the islands. During times of inclement weather, Stolen Stuff Hawaii will continue sharing radar loops for updates. Stay alert, avoid flooded roadways, and monitor conditions closely. #hawaii #weather #alert #rain #flooding
