meteorological history hurricane meteorological history hurricane spanned sixteen days august september storm originated area low pressure associated tropical wave august following day low sufficiently organized classified tropical depression tracking general westward august depression intensified tropical storm given national_hurricane_center attained hurricane status following day eye
