  with property damage in urban or low lying spots due to runoff. Landslides may also occur in areas with steep terrain.

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.

Shelter Information:
Shelters remain open for residents and visitors impacted by the storm. Locations and other details can be found at https://p.veoci.com/hnlshelter. 

City Closures:
Most City offices, all convenience and transfer stations, and City public facilities are closed today due to the storm. Curbside trash pickup, the Bus, Handi-van, and Skyline remain operational. Additional closures and cancellations are likely if storm impacts worsen. Monitor HNL Alert and official social media for updates.

Stay Safe:
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 where 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.
