Hurricane season begins on June 1, but the early months are typically quiet. June averages one named storm every one to two years, while July averages about one or two named storms annually. During this early period, environmental conditions are generally less favorable for intense storm development. Sea surface temperatures are still warming up across the deep tropics, and upper-level wind shear is often strong enough to disrupt forming storm systems.
