Hurricane Flossie is expected to weaken into a tropical storm later on Wednesday. It may re-strengthen and then weaken again before getting closer to Hawaii.

Hurricane Erick will continue to slowly weaken over the next few days and is expected to become a tropical storm as it moves south of Hawaii by the end of the week.
