Tropical storms form when sustained winds reach 40 mph, as demonstrated by Tropical Storm Bertha, which was upgraded from a tropical depression to a tropical storm by the National Hurricane Center; these storms typically move slowly west-northwest and can bring significant impacts including rough surf, rip currents, and rain to coastal regions, even when they don't make direct landfall.
