The sun sets over the mountains as hurricane Irma approaches Puerto Rico in Fajardo on September 5, 2017.
In Puerto Rico, a US territory of 3.5 million, Governor Ricardo Rossello activated the National Guard and announced the opening of storm shelters able to house up to 62,000 people. The major of the Puerto Rican capital San Juan, Carmen Yulin Cruz Soto, ordered 900 municipal employees — police, emergency personnel, and aid and social workers — to report for rotating 12-hour shifts.Even if Puerto Rico is spared a direct hit, the mayor said, three days of pounding rain will do heavy damage.
