The National Weather Service has issued a Flash Flood Watch for Oʻahu, Maui County and the Big Island in effect from Monday morning through Tuesday afternoon.

Areas included in the Watch are: Oʻahu South Shore, Waianae Coast, Oʻahu North Shore, Oʻahu Koolau, Olomana, Central Oʻahu, Waianae Mountains, Molokaʻi Windward, Molokaʻi Leeward, Lanaʻi Makai, Lanaʻi Mauka, Kahoʻolawe, Maui Windward West, Maui Leeward West, Maui Central Valley, Windward Haleakala, Leeward Haleakala, Haleakala Summit, Kona, South Big Island, Big Island North and East, Kohala, Big Island Interior, Big Island Summits.

Heavy showers associated with an upper trough and cold front moving down the island chain could result in flash flooding Monday through Tuesday.

The latest guidance indicates the greatest potential for flooding will occur over Oʻahu, Maui County and the Big Island.

Heavy rain could become widespread and cause streams to quickly overflow their banks, leading to life threatening flash flooding.


A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.


Everyone included in the Watch should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
