Flash Flood Watch in Effect for Big Island

A Flash Flood Watch is now in effect for the Big Island through late tonight, Friday, Feb. 23, 2018.

The combination of strong low pressure aloft to the west and deep moisture lingering around the Big Island will maintain unstable conditions capable of producing periods of heavy rain and thunderstorms.

The areas at greatest risk are the east and southeast slopes, though any given location could experience excessive rainfall and flash flooding.

Areas that received excessive rainfall recently will be more susceptible to flash flooding since the ground is still saturated.

A Flash Flood Watch means that conditions may develop that lead
to flash flooding.

Flash flooding is very dangerous. Avoid flood prone areas.

Monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
