ORIGINAL: 10.20.18, 7:19 AM

The National Weather Service has ISSUED a FLASH FLOOD WATCH for MAUI COUNTY, in effect on Oct. 20, 2018, until this afternoon.

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

EFFECTS: An approaching upper-level disturbance will enhance the deep moisture already in place. Slow-moving and persistent heavy showers and thunderstorms will result in the threat of flash flooding.

Heavy rainfall could result in low spots in roads becoming dangerous and impassible due to severe runoff. Debris in streams and gulches could clog bridges and culverts resulting in dangerous flooding. Isolated landslides could also occur.

PRECAUTIONARY MEASURES: Flash flooding is a dangerous situation. Please continue to monitor the weather forecast and be prepared to take immediate action if Flash Flood Warnings are issued. Campers and hikers should reschedule their outing to a time when weather is expected to be more favorable.
