Weather Advisories Extended
The National Weather Service in Honolulu has extended all advisories on the Big Island.
As of Friday afternoon, the high wind warning is now in effect until 6 a.m. on Monday. The blizzard warning is in effect until 6 a.m. on Sunday and the flash flood watch is in effect through Tuesday afternoon, Dec. 7.
Snow accumulations are anticipated to be up to 12 inches or more and winds on the summits are expected to be 50 to 80 mph with gusts of over 100 mph.
Travel to and around the summits could be difficult to impossible. Blowing snow will significantly reduce visibility at times, with periods of zero visibility. The strong winds will likely cause significant drifting of snow.
Travel should be restricted to emergencies only. If you must travel, have a winter survival kit with you. If you get stranded, stay with your vehicle.
Additionally, flash flooding is possible due to excessive rainfall.
Significant flooding may occur due to the 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. Sections of Highway 11 in the Kaʻū District may close, resulting in long detours or even the isolation of communities. Landslides may also occur in areas with steep terrain.
Be prepared to take action if a Flash Flood Warning is issued. If you experience heavy rain or rising waters, head to higher ground immediately.
