BULLETIN - EAS ACTIVATION REQUESTED

Flash Flood Warning

National Weather Service Honolulu HI

855 PM HST Sat Mar 21 2026



The National Weather Service in Honolulu has extended the



* Flash Flood Warning for...

  The island of Maui in Maui County



* Until midnight HST tonight.



* At 855 PM HST, radar indicated heavy showers and thunderstorms 

  persisting over West Maui, with rain falling at rates of 1 to 2 

  inches per hour. Stream levels remain high across West Maui, and 

  emergency management recently reported road closures in the 

  Lahaina, Kahului, and Wailuku areas. Additional heavy showers are 

  developing south of Maui and are expected to lift northward over 

  the island through the late evening and overnight hours. Given the 

  saturated grounds from recent heavy rainfall, particularly in 

  Kihei, even brief periods of heavy rain could quickly lead to 

  renewed runoff and flooding impacts.



  HAZARD...Flash flooding caused by heavy rain.



  SOURCE...Radar.



  IMPACT...Flooding in drainages, streams, rivers, roads,

           properties, and other low-lying areas. Public road

           closures possible in some areas. Landslides are

           possible in steep terrain.



* Some locations that will experience flash flooding include...

  Kahului, Kihei, Lahaina, Waikapu, Maalaea, Wailuku, Puunene, 

  Waiehu, Waihee, Paia, Haliimaile, Olowalu, Pukalani, Makawao, 

  Kahakuloa, Wailea, Kula, Keokea, Pauwela and Haiku-Pauwela.



PRECAUTIONARY/PREPAREDNESS ACTIONS...



Stay away from streams, rivers, drainage ditches, and culverts, even 

if they are currently dry.



Be especially cautious at night when it is harder to recognize the 

dangers of flooding.



The heavy rains may cause rock and mudslides in steep terrain areas.



&&



This warning may need to be extended beyond midnight HST tonight if 

flooding persists.
