 The final storm of the season developed in the Bay of Campeche on October 18 at the tail end of a frontal boundary . Although cool @-@ air advection was occurring off the United States coast , warm air around the system allowed the tropical storm to intensify . Moving to the northeast , the system reached peak intensity as a high @-@ end tropical storm with winds of 70 mph ( 110 km / h ) . Ultimately , the cool @-@ air advection eventually took a toll on the storm , causing it to quickly weaken . By 06 : 00 UTC on October 21 , the storm dissipated .
