High Winds Preparedness

High winds can cause trees to be blown over, branches to fall, and cause damage to houses and property. Winds ranging from 64 to 137 knots (74-150 mph) can propel debris at dangerously high speeds, posing a risk to life and property. High winds can also cause the rapid spread of wildfires. Situated on the North Shore of Oahu, La'ie often experiences high winds from trade winds, Kona storms, and high winds from tropical storms passing the island.

Understanding Alerts

Wind Advisory

A Wind Advisory is issued when sustained winds of 30 to 39 mph and/or frequent gusts to 50 mph or greater are occurring or imminent.

High Wind Watch

A High Wind Watch indicates sustained winds exceeding 40 mph and/or frequent gusts over 60 mph are likely to develop in the next 24 to 48 hours.

High Wind Warning

A High Wind Warning indicates sustained winds exceeding 40 mph and/or frequent gusts over 60 mph are occurring or imminent.

Red Flag Warning

A Red Flag Warning indicates weather conditions that can cause wildfires to ignite and spread rapidly. High winds combined with dry conditions increase the risk of brush fires, especially in open or undeveloped areas. During a Red Flag Warning, extra caution should be taken to avoid activities that could start a fire.

Preparation

Preparation can be done at any time, not just when a watch or advisory is issued. Recommended steps include:

• Sign up for BYUH Alerts and HNL Info notifications.
• Create an individual or family plan.
  
  • Have a family or friend contact list.
  • Know where to go and plan to shelter in place.
  • Secure all possible flying objects.
• Prepare emergency items for sheltering in place. Include items such as:
  
  • Extra food and water.
  • Flash lights and extra batteries.
  • Power banks and charging cords.
• Know the available resources and sign up to receive updates.
