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.

City and emergency management officials are actively monitoring weather conditions, stream gauges, and water levels in dams and levees. T are no evacuations ordered at this time. The City will provide updates if needed. Staying informed and prepared helps protect both your household and the wider community.

Residents living in dam evacuation zones and other flood-prone areas are encouraged to remain vigilant as heavy rain and possible flooding are forecast over the next several days. Find out if you are in a dam or levee evacuation zone at: www.honolulu.gov/damevac

While t is no immediate emergency, households in these areas should take time now to review emergency plans, check supplies such as food, water, and medications, and ensure phones and essential devices are charged.

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.
