In October, the dry season sets in across much of Florida (starting early in the month in northern Florida and near the end of the month in deep southern Florida) and lasts until late April in most years. Fronts from mid-latitude storms north of Florida occasionally pass through northern and central parts of the state which bring light and brief winter rainfall. Mid and late winter can become severely dry in Florida. In some years the dry season becomes quite severe and water restrictions are imposed to conserve water. While most areas of Florida do not experience any type of frozen precipitation, northern Florida can see fleeting snow or sleet a few times each decade.
