US keeps watch on Matthew: Deadly hurricane sends Florida residents flocking to buy supplies and South Carolina is ready to evacuate over 1 million people as storm kills 11 people in the Caribbean

People along the East Coast entered better-safe-than-sorry mode Tuesday, flocking to hardware stores, grocery aisles and gas stations as Hurricane Matthew marched toward Florida, threatening to become the first hurricane to hit the state's Atlantic coast in over a decade. The storm was on track to rake the Southeastern coast and trek north. South Carolina Gov. Nikki Haley said she planned to issue an evacuation order Wednesday so that 1 million people can safely leave the coast. Matthew, a Category 4 storm packing winds of 145 mph, pummeled parts of Haiti and the Dominican Republic on Tuesday and is expected to head north over Cuba and the Bahamas before nearing the Florida coast by Thursday. At least nine people in the Caribbean have died.
