The Storm’s Grip on Hawaii County
Hawaii County is currently under a weather watch that feels like it’s been brewing for days. The forecast paints a picture of relentless winds and heavy rain, making life quite the challenge for residents and visitors alike.
Starting with the immediate threat, the Flood Watch issued by the National Weather Service covers Niihau, Kauai Leeward, Kauai Mountains, Waianae Coast, Oahu North Shore, Olomana, Central Oahu, Waianae Mountains, Lanai Mauka, Kahoolawe, Maui Windward West, Maui Leeward West, Haleakala Summit, Kona, Kohala, and Big Island Interior. This means that areas known for their lush landscapes are particularly vulnerable to mudslides and landslides.
But it’s not just the rain; strong winds are also a major concern.
The High Wind Warning issued by the Aviation section of the National Weather Service is in effect until 6 PM Monday, covering all islands. These gusts can reach up to 40 knots, causing significant disruptions to travel and daily activities.
Trade Winds: A Constant Presence
The trade winds, which are a staple of life on the islands, have become even more relentless with this storm. The surface high pressure passing north of the state, combined with the deepening trough southwest of Hawaii, is generating strong to gale-force trades across the island chain into Monday.
These winds bring more than just gusts; they also create large and very rough surf along east-facing shores through Monday night. A High Surf Warning has been issued for all exposed east-facing shores, and while this will ease slightly by Tuesday, trade winds are expected to remain strong through the week, with near-gales over windier waters and channels.
Impact on Aviation and Marine Activities
The weather system also poses significant challenges for aviation and marine activities. Airmets (AIRMET Sierra) are in effect for mountain obscuration for all islands, while Airmets Tango warn of moderate to isolated turbulence across all islands and adjacent waters due to the weather system up to FL360.
Surf conditions remain a concern with small to moderate north-northwest swells bringing minor surf to north and west-facing shores. Southern exposures, which are more directly hit by the wind swell, may see larger waves as well. This adds another layer of complexity for those navigating or enjoying the coastal waters.
Looking Ahead: A Long Week
The forecast for the coming days suggests that while the immediate threat of heavy rain and strong winds may ease slightly by Tuesday, conditions are far from ideal. The surface high will intensify tonight, helping to increase winds across the state. By Wednesday, we might see a slight reduction in widespread precipitation, but windward areas can expect numerous showers through the end of the week.
For those planning travel or outdoor activities, it’s wise to keep an eye on local weather updates and be prepared for changing conditions. The resilience of nature is both awe-inspiring and humbling as we navigate these challenging weather events.
This comprehensive forecast outlines the ongoing challenges faced by Hawaii County residents and visitors during this significant weather event, emphasizing the need for preparedness and caution in the days ahead.
