Severe Weather Update 5: March 2026 Kona Low Storm

Details 

Flooding and ponding on roadways is beginning to impact Oahu as a result of the passing Kona Low Storm. Strong winds are expected later today in addition to the heavy rain. Prepare for flooding and power outages over the next few days.

Use caution outdoors and limit travel if at all possible when severe weather conditions are present.

• A Flash Flood Warning is in effect this morning until 11:45am. Additional Flash Flood Warnings are likely as impacts continue.
• A High Wind Watch is in effect from Thursday evening through Saturday night. Southwest winds 25 to 35 mph with gusts up to 60 mph are expected.
• A Flood Watch is in effect through Saturday. Considerable flash flooding remains possible. Persistent bands of heavy rain and thunderstorms may produce intense rainfall rates, leading to rapid rises in streams and flooding of roads and low-lying areas.

The City and County of Honolulu urges residents to avoid unnecessary travel and to stay out of effected areas. Numerous road closures are in effect as a result of storm impacts. Follow all instructions from emergency officials and first responders on scene. If a traffic light is out, treat the intersection as an all-way stop.

The Bus, Skyline, and Handi-van services are operating as normal at this time but some routes may be impacted by road closures.

Residents are reminded of the following closures of City facilities and events:

• City parks facilities and gardens are closed
• Camping permits are suspended
• Royal Hawaiian Band performances are cancelled
• Municipal golf courses are closed
• The Honolulu Zoo is closed

Additional closures and cancellations are likely if storm impacts worsen. Monitor HNL Alert and official social media for updates.

Residents are reminded to use caution and take action to stay safe during the storm.

• Turn around, don’t drown! Do not attempt to walk, swim, or drive through flowing or rising water. Floodwaters can rise rapidly. Just 1 foot of moving water can sweep away a vehicle. If your vehicle is caught in rapidly moving water, stay inside. If water begins to rise inside the vehicle, get on the roof.
• Use extreme caution outdoors and check the weather forecast. Do not cross flooded streams. Streambeds that appear dry can quickly flood due to rain upstream, even if it is not raining w you are.
• Check on others: Individuals and families are encouraged to prepare early, especially households with individuals who may need additional support during severe weather, including older vulnerable adults, people with disabilities, individuals with medical conditions, and those who rely on medical equipment or mobility assistance. Planning ahead can help ensure everyone in the household remains safe and supported as conditions worsen.
