Big Island Friday weather updates: Flood watch, wind advisory, winter weather advisory

Updated April 10, 4:30 a.m.:

On Friday morning, the Big Island was under a flood watch, a wind advisory and a winter weather advisory, according to the National Weather Service.

A flood watch remains in effect for all Hawaiian Islands through Friday afternoon.

Low pressure northwest of the islands will draw deep tropical moisture northward across the state, bringing the potential for heavy rain and thunderstorms capable of producing flash flooding.

Significant flooding may occur due to excessive rainfall and overflow of streams and drainages. Roads in several areas may be closed, along with property damage in urban or low lying spots due to runoff. Landslides may also occur in areas with steep terrain.

A wind advisory for Big Island summits is in effect until 6 p.m. Friday. Southwest winds of 40 to 50 mph with gusts to around 60 mph are forecast. Winds this strong can make driving and walking dangerous. The winds can forcefully open doors and damage hinges or slam doors shut, possibly causing injuries.

A Winter weather advisory for island summits above 12,500 feet has been extended until Friday at 6 p.m.

An upper low will maintain moisture over the Big Island and bring the potential for snow and freezing rain.

Additional snow accumulations up to 4 inches and ice accumulation up to a quarter inch are possible.

The Mauna Kea Access Road is closed. Ice accretion and snow on roads from this storm will make travel to the summits very difficult to impossible. Visibility may be significantly reduced.

The Kea‘au-Pāhoa Road Northbound Contraflow will be set up as Hawai‘i Island schools and state offices will be open.
