What are the chances Olivia will stay a hurricane as it passes over Hawaii?
According to the Central Pacific Hurricane Center, it’s possible. The forecast takes Olivia down to tropical storm status before it reaches Hawaii, however the storm is entering warm waters, so it may maintain its strength as a hurricane.
Keep in mind, the difference between a weak Category 1 hurricane and a strong tropical storm is 1 mph (maximum sustained winds). A Category 1 hurricane has between 74-95 mph winds, while a tropical storm has winds between 39-73 mph.
