Danny, the first hurricane of the 2015 Atlantic season, is not expected to further intensify. “Danny is moving into an area of unfavorable upper-level winds, and a weakening trend is expected to begin later today,” said the advisory. Danny is expected to reach Puerto Rico in about 96 hours, according to an earlier advisory.
