Hurricane Maria, an "extremely dangerous" storm, made landfall on the small island of Dominica Monday night as a Category 5 storm, then weakened ever-so-slightly to a Category 4, the U.S. National Hurricane Center (NHC) said early Tuesday.

After battering Cuba early Saturday and leaving more than 20 dead across the Caribbean, a dangerous Hurricane Irma is taking aim at south Florida with winds nearing 160 mph as another hurricane follows close behind.  

Hurricane Irma has killed at least 10 people and injured 23 in French Caribbean island territories as the dangerous Category 5 storm roared over the Caribbean, France's interior minister said Thursday.
