HONOLULU, Hawaii (HawaiiNewsNow) - A persistent upper disturbance will have the potential to bring a prolonged periods of rainfall to parts of the state this weekend.

The ground may become saturated and increase the threat of flooding as more bands of heavy rain move in, prompting a handful of weather advisories.

The flash flood for Maui Saturday morning was cancelled as of 11:30 a.m. Stream gauges showed rapidly rising waters levels in the Nahiku, Hana and Kaupo areas.

Both Oahu and Hawaii Island were placed under a lesser urgent flood advisory until 1:15 p.m.

With the added moisture in the atmosphere, the National Weather Service has issued a flash flood watch for windward areas of Maui and the Big Island due to expected persistent rainfall through the weekend.

NWS Honolulu says the watch is posted until 6 p.m. Sunday.

Flood prone roads and other low-lying areas may be closed because of elevated runoff and overflowing streams. Landslides are also possible in steep terrain.

A flash flood watch means that conditions are favorable for flash flooding. You should be prepared to take quick action if heavy rain or rising waters occur in your area, or a flash flood warning is issued.

A winter weather advisory is also posted for the summits of Mauna Kea and Mauna Loa through noon Monday for possible freezing rain and snow.
