The National Weather Service has cancelled the flash flood watch for Maui County and the Big Island of Hawai’i.

The flood watch for Niihau, Kauai and Oahu remains in effect through Sunday.

The wet weather over the western portion of the state is due to a low aloft, centered just west of Kauai.  The low will drift east toward Oahu this afternoon and tonight, according to NWS forecasters.

Trades are expected to keep showers moving along, but there is still a good chance that heavy rain will become anchored over windward areas of affected islands.

A flood warning remains in effect for the island of Maui until 7:15 a.m.

Radar images continue to show rainfall at rates of 3-5 inches per hour in affected areas.

The National Weather Service says there is an enhanced threat in areas of steep terrain along the windward and southeast slopes of Haleakala.

A flash flood warning means that flash flooding is imminent or already occurring in streams, roads and low-lying areas.

Motorists and pedestrians are reminded not to cross fast flowing or rising water in their vehicle or on foot.

Forecasters say the flood warning may extend beyond 7:15 a.m. if heavy rain persists.
