SAN JUAN, Puerto Rico (AP,Sept 4,2017): — Hurricane Irma grew into a powerful Category 4 storm Monday as it approached the northeastern Caribbean and was forecast to begin buffeting the region Tuesday.
The storm had maximum sustained winds of 130 mph (215 kph) late Monday afternoon, and the U.S. National Hurricane Center said additional strengthening was expected. Irma was centred 490 miles (790 kilometres) east of the Leeward Islands and moving west at 13 mph (20 kph).
Emergency officials warned that the storm could dump up to 10 inches (25 centimetres) of rain, unleash landslides and dangerous flash floods and generate waves of up to 23 feet (7 metres) as the storm drew closer.
“We’re looking at Irma as a very significant event,” Ronald Jackson, executive director of the Caribbean Disaster Emergency Management Agency, said by phone. “I can’t recall a tropical cone developing that rapidly into a major hurricane prior to arriving in the central Caribbean.”
The storm’s centre was forecast to move near or over the northern Leeward Islands late Tuesday and early Wednesday, the hurricane centre said.
