Erin intensifies into hurricane as it tracks near Puerto Rico, Leeward Islands Hurricane Erin will rapidly intensify into a powerful storm, and over the weekend, it is expected to pass close enough to Puerto Rico and the Leeward Islands to unleash heavy rain, strong winds and pounding surf. AccuWeather meteorologists say a turn toward the west-northwest is likely before Erin reaches the islands. #ErinNearPuertoRico #CaribbeanStormAlert #HurricaneTrackUpdate
