Florence is forecast to restrengthen into a hurricane and push close to Bermuda and the United States East Coast next week.

Wind shear is the increase in wind speed and change in wind direction with either increasing altitude or over a horizontal distance. Low wind shear can prevent a tropical storm from forming and cause a well-developed hurricane to weaken. READ MORE
