 In the hours after becoming a tropical cyclone , the deep convection associated with the depression decreased , though it again increased later in the day . A ragged rainband developed in the southeastern quadrant of the circulation , and based on increased Dvorak numbers and improved presentation on satellite imagery , the National Hurricane Center upgraded the depression to Tropical Storm Barbara on May 30 while it was located about 115 miles ( 185 km ) south of Puerto Escondido . This marked only the third time on record that two storms formed in May in the basin , after 1956 and 1984 . Initially , Barbara was forecast to intensify to attain hurricane status and reach winds of 85 mph ( 135 km / h ) .
