The island of Maui in Maui County * Until 145 AM HST. * At 1035 PM HST, radar indicated heavy showers and thunderstorms expanding across all of Maui, with rainfall rates of 1 to 3 inches per hour now occurring island-wide. Emergency management continues to report road closures in the Lahaina, Kahului, and Wailuku areas. Additional heavy showers developing and lifting northward over the island will likely continue through the overnight hours.

HAZARD...Heavy rain producing life threatening flash flooding. SOURCE...Radar. IMPACT...Significant and life threatening flooding in drainages, streams, rivers, roads, properties, and other low lying areas. Multiple public road closures expected, as well as landslides in steep terrain. * Some locations that will experience flash flooding include... This includes the entire island of Maui. PRECAUTIONARY/PREPAREDNESS ACTIONS... Stay away from streams, rivers, drainage ditches, and culverts, even if they are currently dry. Be especially cautious at night when it is harder to recognize the dangers of flooding. The heavy rains may cause rock and mudslides in steep terrain areas. This replaces the previous Flash Flood Warning for West Maui. && This warning may need to be extended beyond 145 AM HST if flooding persists.
