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. Matthew, a Category 4 storm packing winds of 145 mph, pummeled parts of Haiti and the Dominican Republic on Tuesday. The eye of Hurricane Matthew has now moved off the northeastern coast of Cuba (center inset) as the storm is expected to head over to the Bahamas before nearing the Florida coast by Thursday. Florida residents emptied store shelves buying food supplies and other items crucial to survive the storm (top). A United Nations official said Hurricane Matthew has caused the biggest humanitarian crisis in Haiti since the devastating earthquake of 2010.
