The weather patterns across the Atlantic, Caribbean, and Gulf have transitioned into a wintertime mode, according to a hurricane analysis by Bryan Norcross published by FOX Weather. Officials designate the official hurricane season from June through November simply because tropical development has historically shown the highest probability of occurring during that period.
While out-of-season tropical storms have occasionally formed, most past systems outside the traditional window have not affected the United States. One historical out-of-season system eventually struck eastern North Carolina near hurricane strength, though it had already transformed into a non-tropical, nor'easter-style system by that time.
Winter Outlook
Looking ahead, a powerful El Niño is expected to energize disruptive weather throughout the United States. This includes impacts within the hurricane zone as the winter season progresses.
