Locations in the advisory include but are not limited to: Kahului, Lahaina, Pukalani, Makawao, Hāliʻimaile, Kula, Pāʻia, Haʻikū-Paʻuwela, Paʻuwela, Puʻunēnē, Huelo, Māʻalaea, Wailuku, Keʻanae, Waiehu, Waikapū, Waiheʻe, Nāhiku, Kīpahulu and Kahakuloa.
As a precaution, the public is advised to stay away from streams, drainage ditches and low-lying areas prone to flooding.
The NWS advises that rainfall and runoff will also cause 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.
There is also a flood watch that remains in effect through late Tuesday night.
The NWS forecast calls for deep moisture to spread over Maui County from the east and southeast on Monday, then linger into Tuesday, bringing the potential for persistent heavy rain that could lead to flash flooding.
