Early Friday, March 20, 2026, Oʻahu woke to an HNL Alert warning of a Flood Advisory for the island. Officials said the advisory could bring minor flooding to some roads and streams and urged residents to steer clear of standing water. The Honolulu emergency account repeated the now-familiar safety mantra, “Turn around, don’t drown,” and reminded people that emergencies should be reported to 9-1-1.
What officials are saying
According to Oahu Emergency Mgmt., the Flood Advisory warns of “minor flood impacts to some roads and streams” and tells islanders to avoid flooded areas while conditions persist. The post also linked to forecast details for the advisory and reminded followers that social accounts are not monitored for emergencies. Officials stressed that drivers should not attempt to cross fast-flowing water.
NWS advisories and safety guidance
The National Weather Service in Honolulu says a Flood Advisory signals nuisance flooding that can make low-lying roads and drainage channels impassable. NWS guidance echoes the city’s message: never drive through standing water, “Turn around, don’t drown,” and seek higher ground if streams begin to rise. For practical driving and evacuation tips, see the flood safety guidance from the National Weather Service.
Local context
This advisory arrives after a stretch of wet weather that produced similar island warnings earlier this month, as detailed in reporting that soaked a Friday evening. Local reporting from that period documented rapid runoff, ponded streets and travel delays in windward communities. Because these rain bursts are often highly localized, officials warn conditions can change quickly from dry to flooded.
