Alerts (Updated at 12 p.m.)

The FLOOD ADVISORY has been extended for the island of Moloka’i until 2:45 a.m. Radar showed moderate to heavy rain along Highway 450. The moderate to heavy rain is expected to continue over the next couple of hours at a rate of about 1 inch per hour.

The National Weather Service has issued a Flash Flood Watch for Maui through 6:00 a.m. Thursday. An area of instability is expected to push moisture up toward the island that could potential cause flooding and thunderstorms through Wednesday night. The rainfall will mainly focus over windward areas. Excessive runoff could result in rock and mudslides in steep terrain. Fast-moving waters could create life-threatening conditions.
