High winds and heavy rainfall swept through Hawaii over the weekend, leaving thousands without power and prompting state officials to take precautionary measures. The severe weather, caused by a low-pressure system to the south and a high-pressure system to the north of the islands, resulted in significant impacts across the state, particularly in Maui and Oahu.
Emergency Proclamation Issued Ahead of Storm
Hawaii Governor Josh Green declared an emergency proclamation ahead of the storm, which led to the closure of schools, public buildings, and institutions such as the University of Hawaii. In a statement, Green emphasized the importance of safety: "The safety of our residents and visitors is our top priority. We know this storm system could bring conditions that make travel unsafe and threaten property. Please take this time to secure your home, check on loved ones and heed guidance from emergency officials."
A member of Green’s staff witnessed a tree fall on a power line early Sunday morning, illustrating the dangers posed by the high winds. Hawaiian Electric Co. reported that more than 12,000 residents across Oahu and Maui County were without power as of Sunday afternoon.

Intense Weather Conditions Across the Islands
The storm system brought gusts ranging from 50 to 73 mph throughout the islands, with winds particularly strong downwind of higher terrain and through valleys. By Monday, a high wind warning was in effect, with gusts of up to 60 mph expected until 6 p.m. local time.
Rainfall was widespread, with the highest elevations on the islands receiving over a foot of precipitation over the weekend. Lower elevations experienced rainfall totals ranging from 0.5 to 3 inches. Among notable recordings, Hilo received 2.53 inches of rain, Kahului saw 1.33 inches, and Honolulu recorded 0.6 inches.
In addition to rain, Big Island summits surpassing 12,000 feet in elevation were blanketed with heavy snow, with projections of a foot or more of snowfall by Monday.
Weather and Drought Challenges
While the rainfall did provide some relief to regions experiencing severe drought, including Maui and the Big Island, the storm’s intensity raised concerns about flash flooding and runoff. These conditions may damage vegetation and harm soil health. Parts of Maui and the Big Island remain under extreme drought conditions, categorized as level 3 out of 4.
Looking Ahead
The storm’s most severe impacts were expected to ease by Monday afternoon. Following the storm, weather conditions are projected to normalize, with typical trade winds and passing showers anticipated through the remainder of the week.
Despite the challenges posed by the storm, state officials are working to ensure that recovery efforts proceed smoothly. As the islands return to calmer conditions, residents and visitors are advised to remain cautious and follow updates from local authorities as needed.
