Hurricane Erin weakened to a Category 3 hurricane overnight, but still remains a formidable major hurricane. Erin had max winds of 125 mph, the National Hurricane Center said in a 5 a.m. ET update. The next update is expected at 8 a.m. ET.

Powerful Hurricane Erin has undergone a period of astonishingly rapid intensification — a phenomenon that has become far more common in recent years as the planet warms. It was a rare Category 5 for a time Saturday before becoming a Category 4, churning through the Atlantic Ocean north of the Caribbean.
