Maui woke up under a flood advisory that runs through 11:00 a.m. HST on Monday, March 23, 2026, officials said. Forecasters are warning that heavy showers could lead to ponding on roadways, rising streams and low-water crossings that may quickly become impassable. Local authorities are urging residents and visitors to use extra caution near drainage channels and to keep a close eye on changing conditions.
Official alert and emergency instructions
The Hawaii Emergency Management Agency shared the advisory on X, noting that it applies to Maui through 11:00 a.m. HST and reminding the public that its social media accounts are not monitored around the clock and that people should call 9-1-1 for life-threatening emergencies, according to the Hawaii Emergency Management Agency. The post is the latest statewide alert tied to the kona-low pattern that has been sending repeated rounds of heavy rain across the islands.
What forecasters are tracking
The National Weather Service in Honolulu has issued flood watches and advisories as a Kona low pulls tropical moisture over the islands, setting up bands of heavy rain capable of rapid runoff and localized flooding, according to National Weather Service in Honolulu. Forecasters say brief downpours may deliver rainfall rates of an inch or more per hour in some locations and are repeating their familiar warning to drivers who encounter standing water: "Turn Around, Don't Drown."
Local impacts and where to check for closures
Maui County is keeping a rolling list of road closures, shelter statuses and storm updates on its alerts page as crews watch low-lying areas and previously damaged infrastructure, according to County of Maui alerts page. Travelers should be ready for slow or limited access on roads affected by the storm and are advised to follow directions from local emergency managers.
For ongoing information, rely on official state and county channels. If you are in immediate danger, call 9-1-1. For non-emergency details on roads and shelters, check county alerts and National Weather Service products online.
