 Hurricane Danielle resulted in minor damage throughout its duration as a tropical cyclone in late August and early September 1998 . The fourth named storm and second hurricane of the annual hurricane season , Danielle originated from a tropical wave that emerged off the western coast of Africa on August 21 . Tracking generally west @-@ northwestward , the disturbance was initially disorganized ; under favorable atmospheric conditions , shower and thunderstorm activity began to consolidate around a low @-@ pressure center . Following a series of satellite intensity estimates , the system was upgraded to Tropical Depression Four during the pre @-@ dawn hours of August 24 , and further to Tropical Storm Danielle that afternoon . Moving around the southern periphery of the Azores High located in the northeastern Atlantic , quick intensification to hurricane status occurred early on August 25 . By 0600 UTC the following day , Danielle reached an initial peak intensity of 105 mph ( 165 km / h ) , a Category 2 hurricane . Increased wind shear from a nearby trough encroached on further development later that day , and subsequently led to slight weakening . By 1200 UTC on August 27 , despite continued unfavorable conditions , Danielle reached a second peak intensity equal to the first . Weakening once ensued late on August 27 in addition to the days following , and Danielle was a low @-@ end Category 1 hurricane by August 31 as its forward speed slowed .
