The Island of Maui is under a Flood Advisory until 10 a.m. The National Weather Service issued the advisory shortly after 7 a.m.

Radar showed heavy thundershowers located 7 miles north-east of Hana, Maui, moving west at 15 miles per hour.  Forecasters say additional downpours were already developing over the windward slopes of Haleakala as well.

Other locations in the advisory include, but are not limited to: Hamoa, Nakiku, Kipahulu, Keanae, Kaupo, Huelo and Pauwela.

As a precaution, travelers on the road to Hana should be alert to hazardous driving conditions due to ponding, reduced visibility, and poor braking action.  Motorists and pedestrians are reminded not to cross fast flowing or rising water in their vehicle or on foot.
