The National Weather Service is saying that Hurricane Matthew, which is currently barreling across the coast of Florida, is "unlike any hurricane in the modern era." President Obama has declared a state of emergency in the state, and Florida Gov. Rick Scott warned that "this (storm) will kill you." Here are the latest updates on the storm:
• It's been downgraded from Category 4 to a Category 3 storm, which is the third-highest hurricane classification category on the Saffir-Simpson Hurricane Scale, indicating maximum sustained winds of 110-130 mph.
• So far, it has left at least 280 deaths in its wake as it surged through the Caribbean yesterday.
• The storm's outer eye wall is approaching NASA's facilities at Cape Canaveral and the government's nearby next-generation weather satellite.
• In the largest mandatory evacuation since Hurricane Sandy hit the East Coast in 2012, more than 2 million people were urged to leave their homes in coastal Florida, Georgia, and South Carolina as the storm approached.
• As the storm barrels across the state, hundreds of thousands were without power in Florida early Friday morning. Check weather.com for all the latest updates.
