Weather Alert in Oahu
WEATHER ALERT: Reposting from Stolen Stuff Hawaii NWS Hawaii Weather Radar Loops - 5:10AM - 3/20/2026 KONA LOW IMPACTS STATEWIDE Heavy rain and thunderstorms continue to impact the state as a Kona low remains stalled near the islands, bringing dangerous and ongoing weather conditions. Radar shows a persistent band of heavy rain focused over Oʻahu, with additional bands extending toward Maui County and the Big Island. Kauaʻi is seeing lighter, more scattered showers as conditions improve there. We are continuing to see serious and devastating flooding impacts, particularly in areas like Waialua and Haleʻiwa, along with other parts of the island. Conditions remain dangerous, and additional flooding is likely as heavy rain continues to move over already saturated areas. Local forecasts from the National Weather Service indicate periods of heavy rain, strong gusty kona winds, and possible thunderstorms continuing through today and into Saturday, with a high risk of additional flooding statewide. Repeated rain bands may lead to several more inches of rain in some areas. Conditions are expected to remain unsettled through Saturday before gradually improving on Sunday, though runoff and flooding impacts may persist even after rainfall begins to decrease. During times of inclement weather, Stolen Stuff Hawaii will be sharing the NWS Hawaii Weather Radar loops periodically for an easy update. The colored scale along the bottom shows radar intensity, measured in dBZ, which indicates how heavy the precipitation is. Cooler colors like blue and green represent light rain, yellow indicates moderate rain, and orange to red shows heavy rain or strong storm cells, with purple representing the most intense returns. The bar at the top is a legend for weather alerts that the National Weather Service may issue on the map. Each color represents a different type of warning, such as tornado (red), severe thunderstorm (yellow), flash flood (green), special marine (orange), or snow squall (purple). When you see a colored polygon on the radar, it means that particular warning has been issued for the area inside that outline.
