What's Happening?

A powerful kona low storm is set to bring hazardous weather conditions across the Hawaiian Islands through the weekend. According to the National Weather Service (NWS) Honolulu, the storm will result in significant flash flooding, damaging winds, and snow and ice over the highest Big Island summits. The storm is dragging deep tropical moisture over the islands, leading to rainfall totals that could reach up to a foot in the hardest-hit areas. The strongest southwesterly winds are expected from Friday to Saturday, producing damaging gusts along the north and east of the island mountains. Unsettled wet weather conditions will persist into early next week, with the storm beginning to lift northward on Monday, easing the weather across Hawaii.

Why It's Important?

The storm poses significant risks to the 1.4 million residents of Hawaii, with numerous weather warnings in place. These include flash flood warnings, gale warnings, winter weather advisories, high wind watches, and winter storm watches. The NWS has issued a flood watch, warning of potential significant flooding due to the overflow of streams and drainages. Roads may be closed, and property damage is possible in urban or low-lying areas due to runoff. Landslides may occur in areas with steep terrain, posing additional risks to residents and visitors.

What's Next?

The kona low storm is expected to bring its strongest impacts from Friday through Saturday, with damaging winds and heavy rainfall. Rainfall totals could reach between 15 and 20 inches in Honolulu, nearly an entire year's worth of rain over five days. High-elevation areas might see between 20 and 30 inches of rain. The storm will begin to lift northward on Monday, with unsettled weather easing across the region. High pressure will build north of the state, allowing trade winds to return from Wednesday onward.
