 The storm originated in an upper @-@ level low pressure system that moved southeastward from the central Great Plains into the Deep South of the United States . After reaching the southeast Gulf of Mexico , the disturbance underwent cyclogenesis , and the resultant system moved through Florida on December 22 in response to an approaching trough . National Hurricane Center forecaster Jack Beven noted that " as it moved out into the Bahamas , it appeared to take on the characteristics of a tropical storm . " The uncertain nature of the storm prevented the NHC from issuing advisories on it , and forecasters lacked sufficient data to fully assess the cyclone for potential tropical characteristics . The same trough that pushed the storm across Florida had moved to the north , allowing for high pressure to develop in the upper levels of the atmosphere .
