The National Weather Service in Honolulu has canceled the flood advisory originally issued for Kauai but has introduced a special marine weather warning for the waters surrounding the island. As of 11:28 a.m., strong thunderstorms were detected over the waters near Kauai, with wind gusts reaching 34 knots or higher, accompanied by small hail. These conditions pose a risk to small crafts, which could sustain damage from sudden higher winds and waves. The advisory affects the Kauai Channel, as well as leeward, windward, and northwest waters around the island, remaining in effect until 12:30 p.m.
Meanwhile, a significant portion of Oahu is under a flood advisory until 12:30 p.m. today. The National Weather Service has indicated that minor flooding could occur on roads, in streams, and areas with inadequate drainage. Earlier, at 9:17 a.m., heavy rain was recorded over windward Oahu with precipitation rates of one to two inches per hour. This advisory encompasses multiple locations, including Honolulu, Waipio, Waiahole, Waikane, Kahaluu, Ahuimanu, Aiea, Pearl City, Kaaawa, Halawa, Mililani, Moanalua, Punaluu, Salt Lake, Kaneohe, Wahiawa, Kalihi, Wheeler Field, Hauula, and Kaneohe Marine Base. Residents are advised to avoid streams, drainage ditches, and low-lying flood-prone areas.
Earlier today, a flood advisory was active for Kauai until noon, with radar at 8:59 a.m. showing heavy rain over windward areas. Rainfall was occurring at rates of one to two inches per hour, impacting locations such as Lihue, Kapaa, Princeville, Kilauea, and others. However, by 7:20 a.m., the flood advisory for Oahu had been lifted as radar indicated diminishing rainfall over the island.
Additionally, a winter weather advisory is in place for Hawaii Island’s summits above 11,000 feet, effective from noon today through 6 p.m. Friday. A slow-moving upper-level trough is predicted to deliver three to five inches of snow, potentially reducing visibility to near zero as snow blows across the area. Travel to these summits could be very challenging, and caution is advised for anyone planning to visit.
Forecasters predict the state will continue experiencing a convective weather pattern with light winds and scattered showers throughout the weekend. Moderate tradewinds are anticipated to return by early next week, although lingering moisture may allow showers to persist, even in typically drier leeward areas. An emerging storm system west of the state could bring southerly winds, heavy rain, and thunderstorms by Tuesday or Wednesday.
Context and Clarity
The current weather conditions across Hawaii have significant implications for residents and visitors alike. The advisories highlight the need for caution and preparation, particularly for those in affected areas. The potential for minor flooding in Oahu and hazardous marine conditions around Kauai could disrupt daily activities, including travel and outdoor plans. Residents and tourists should remain vigilant and adhere to safety recommendations to avoid hazards such as flooding and challenging road conditions.
For those residing in or visiting Hawaii Island, the winter weather advisory emphasizes the potential risks associated with traveling to high-altitude areas. Reduced visibility and difficult travel conditions could pose serious challenges, underscoring the importance of planning accordingly and heeding weather advisories.
The broader weather patterns indicate a continued period of unsettled weather, with the potential for storms early next week. This highlights the need for residents to stay informed about weather developments and maintain readiness for changes in conditions that could impact daily life and safety.
