All Maui County residents should know that a Flash Flood Watch remains in effect countywide until late Thursday afternoon. Please note that flash flood conditions can develop at a moments notice due to the ground being already saturated and streams at very high levels.

-Update- 

The National Weather Service has EXTENDED the FLASH FLOOD WATCH for MAUI COUNTY, now in effect until Friday afternoon.

A Flash Flood Watch means that conditions may develop that lead to flash flooding.

EFFECTS: Abundant tropical moisture and an upper level trough will continue the threat of heavy rainfall and flooding. The very moist and unstable air mass interacting with an upper level trough will result in unsettled weather with potential for flash flooding through Friday.

Emergency Proclamation

Mayor Alan Arakawa signed an emergency proclamation today following torrential flooding through Iao Valley that knocked out a waterline, flooded several homes with mud and debris and destroyed a significant portion of the County’s Kepaniwai Park parking lot area.

Due to hazardous conditions, access to Iao Valley is currently restricted to residents only.

Road Advisories

  • Wailuku area – Iao Valley Rd -320 is open to local residence only.
  • Lahaina area – Honoapiilani Hwy – 30 on the Pali west bound through Ukumehame to the Puamana area. Traffic is very heavy and slow due to flooding.
  • Hana area – Piilani Hwy-31 between mile marker 29- Manawainui Gulch and mile marker 30 – Pahihi River, falling rocks and the rivers are overflowing. Crews are heading and will attempt to clear debris.
  • Ulaino Rd at the first river – Closed.

Boil Water Advisory for Central and South Maui Areas

A waterline that was washed away in the flooding interrupted water service to residents in Iao Valley, and the Department of Water Supply (DWS) provided six water tankers for affected customers. Water service has since been restored in the area after emergency repairs were made by DWS.

Debris also clogged the intake at the Lahaina Water Treatment Plant; the intake is being cleared and the plant is expected to be restarted soon. Water customers in Lahaina are asked to conserve water and avoid unnecessary water use to help preserve supplies for safety use such as fire-fighting.

DWS asks customers in Central and South Maui to conserve water and to boil water before consumption due to possible contamination from flooding. Affected areas include Iao Valley, Kahului, Wailuku, Paia, Spreckelsville, Puunene, Kihei, Wailea, Makena and Maalaea

The Department of Water Supply is recommending customers in the Central and South Maui areas to boil water before consumption due to possible contamination from flooding. Affected areas include Kahului, Wailuku, Paia, Spreckelsville, Puunene, Kihei, Wailea, Makena and Maalaea. At this time, there are no water quality violations. This advisory is a precautionary measure for public health and safety purposes.

Customers should boil water at a rolling boil for 3 minutes prior to consumption or use, or use bottled water. DWS personnel are out in the water system flushing water lines to ensure clean water, and laboratory personnel will take samples to verify water quality today. Another press release will be issued once samples show no contamination.

The Department of Water Supply is also requesting all consumers in the Wailuku and Kahului areas to conserve water and to avoid any unnecessary water use until further notice.

The Department of Health recommends that ice cubes used for consumption (i.e. beverages) should be discarded to avoid contamination, and soda dispensing machines drawing water should use boiled water or turned off to avoid contaminating beverages.
