Overview
- The National Weather Service has a Flood Watch in place statewide through at least Monday afternoon as heavy rain and isolated thunderstorms pose risks of flash flooding and landslides.
- A Winter Storm Warning for Mauna Kea and Mauna Loa above 11,000 feet remains in effect until 6 a.m. HST Tuesday, with heavy mixed precipitation and significant rime icing on summit roads.
- Snow projections differ, with NWS guidance calling for about 5 to 10 inches of additional accumulation while the FOX Forecast Center expects up to six inches.
- High wind warnings at the summits call for southeast winds of 50–60 mph with gusts up to 75 mph, creating whiteout conditions that could make travel impossible.
- East-facing shores are under a high surf advisory for 8–12 foot waves through Wednesday, and the Kona low is forecast to weaken by midweek with a weaker disturbance possible later.
