National Weather Service (NWS) meteorologists in Honolulu are warning that some parts of Hawaii could see up to 8 inches of snow with an incoming winter storm set to arrive Wednesday night.

Why It Matters

The winter season is typically Hawaii’s wet season, meaning the islands often see stronger winds, dangerous waves and rainfall. However, the incoming low-pressure system is uncommon for the tropical region, meaning some people could be caught unawares.

The NWS office in Honolulu has issued myriad weather alerts to notify people of the incoming storm, including a winter storm watch, high wind watch, and flood watch.

What To Know

The storm is set to bring impacts to all Hawaiian Islands as early as late Wednesday night. According to the weather alerts in place, the impacts will persist through Friday morning.

Meteorologists are warning of 4 to 8 inches of snow on Hawaii’s summits, as well as a “light glaze of ice” as temperatures drop below freezing.

Despite Hawaii being more commonly known as a warm climate, it is not unusual for snow to fall on the state’s volcanic peaks given their altitude, and blizzard warnings have been issued during the winter months.

NWS meteorologist William Ahue told Newsweek that his biggest concern with the incoming storm is the rainfall. Some areas could see up to 3 inches of rain with the storm, which will contribute to the risk of flash flooding. Although January is during Hawaii’s wet season, Ahue said most islands aren’t accustomed to seeing that much rain at one time.

Winds also will be damaging. A high wind warning currently in place warns that some wind gusts could reach up to 90 mph, which is the equivalent of a Category 1 hurricane.

What People Are Saying

NWS Honolulu in a winter storm watch: “Travel could be very difficult to impossible. Blowing snow will significantly reduce visibility at times, with periods of zero visibility.”

The watch continued: “A Winter Storm Watch means there is potential for significant snow or ice accumulations that may impact the summits. Anyone planning travel to the summits, including hikers and campers, should monitor the latest forecasts and consider postponing their trip until improved weather returns.”

NWS Honolulu in a flood watch: “A strong winter low pressure system approaching will pass north of Kauai on Thursday, with a cold front advancing down the island chain Thursday through Friday. The threat of heavy rainfall and thunderstorms developing along and ahead of the front will quickly increase tonight and persist through Friday.”

What Happens Next

Many of the watches across the islands could turn to warnings that alert people to more immediate danger as the storm draws closer. Residents and visitors are urged to monitor local weather offices and be prepared.
