The impact of Hurricane Irma in Miami, FL, USA, 10 Sept 2017 (AP)
Irma was downgraded from a hurricane to a tropical storm today after slamming Florida with destructive wind, heavy rain, flash flooding, high storm surges and even tornadoes.
Irma, one of the most powerful hurricanes ever recorded in the Atlantic Ocean, made landfall over the Florida Keys on Sunday before coming ashore near Naples and then heading up the state’s west coast.
Miami was not in the storm’s direct path but was still battered by strong winds which swayed high rise buildings, brought down three construction cranes and downtown streets were swamped.
In northeast Florida, Jacksonville had historic flooding after the swollen St. Johns River spilled its banks and officials said dangerous conditions were expected for several days.
Prior to arriving in the United States, Irma claimed 10 lives in Cuba according to state media after battering Havana and tourist resorts such as Varadero and Cayo Coco where the international airport was destroyed.

Harvey may have been downgraded to a tropical storm as it moved inland over Texas but the U.S. National Weather Service stated “this event is unprecedented and all impacts are unknown and beyond anything experienced.”
Forecasters say the Houston metropolitan area could receive more than 1000 mm of rain from the storm over the next few days which has claimed at least five lives.
By early today, more than 600 mm had fallen in America’s fourth largest city overwhelming lakes and rivers forcing thousands of residents scrambling into boats or onto rooftops to safety.
Tornado warnings have been lifted but a flash flood warning remains in place for much of southeastern Texas.
