The Maui Emergency Management Agency (MEMA) has issued flood advisories for several flood-prone areas in Maui County, including 'Īao Valley, South Kīhei, East Moloka'i, Lahaina, and East Maui, in preparation for the upcoming Kona storm. Many of these areas are known to be vulnerable to flooding during periods of heavy rainfall.

Why it matters

Flooding can pose a significant threat to public safety and property, especially in low-lying and coastal areas. The Kona storm is expected to bring heavy rainfall, which could exacerbate existing flood risks in these vulnerable communities. MEMA's proactive measures to issue flood advisories and encourage residents to prepare are crucial for mitigating the potential impacts of the storm.

The details

According to MEMA, South Kīhei has been identified as a high-risk area for flooding due to significant sediment accumulation from the recent Kona low storm. Ongoing cleanup efforts are focused on restoring drainage capacity, but elevated flood risk remains. Other areas of moderate risk include 'Īao, East Moloka'i, Lahaina, and East Maui. Residents and visitors in these areas are encouraged to prepare emergency go-bags and maintain enough supplies to shelter in place for up to 14 days in case access to services is limited.

  • The flood advisories were issued by MEMA at 8:45 p.m. on March 19, 2026.
  • The Kona storm is forecast to reach the state beginning on March 20, 2026.
