 Tropical Depression Six developed offshore of the Southeastern United States on September 22 from the merger of a surface trough , a tropical wave , and a cold front . The depression quickly intensified and was upgraded to Tropical Storm Danielle six hours later . An approaching trough caused a northeastward movement , but later a high pressure system forced the storm to northwestward , which caused Danielle to execute a small anti @-@ cyclonic loop on September 23 – 24 . While offshore of North Carolina on September 25 , Danielle reached its peak intensity as a moderately strong tropical storm with maximum sustained winds of 65 mph ( 100 km / h ) . It was initially predicted that Danielle would make landfall in North Carolina , however , the storm curved north @-@ northwestward and made landfall in Maryland on the eastern shore of the Delmarva Peninsula at the same intensity . Danielle continued inland and weakened and dissipated over eastern Pennsylvania on September 26 .
