High Quality Content by WIKIPEDIA articles! Hurricane Isaac was the final tropical cyclone of the 2006 Atlantic hurricane season. Isaac originated in a tropical wave that entered the Atlantic Ocean on September 18. An associated area of disturbed weather eventually organized sufficiently to be declared a tropical depression on September 27, while located 930 mi (1,500 km) southeast of Bermuda. The depression was upgraded to a tropical storm just 12 hours later, though unfavorable atmospheric conditions, including high wind shear and cool water temperatures, initially inhibited further intensification. Isaac ultimately peaked as a Category 1 hurricane on the Saffir-Simpson Hurricane Scale, and brushed Newfoundland as a tropical storm. Effects from the storm were minimal and limited to gusty winds, rough surf, and sporadic rainfall.
