Hurricane Irma kills at least 30 in Caribbean as Florida braces for storm. Hurricane Irma is continuing to tear a deadly path through the Caribbean, causing widespread destruction and reducing buildings to rubble, on a track that could lead to a catastrophic strike on Florida. The American state is bracing for the arrival of the Atlantic’s most deadly storm in history, which has already left at least 10 people dead and thousands homeless. Emergency chiefs warn it will have a “truly devastating” impact on the US. The United Nations estimates that up to 37 million people could be affected by the category five hurricane, which was sustaining winds of 180mph as it moved off the northern coast of the Dominican Republic on Thursday.
