Thousands of people have been ordered to evacuate part of North Carolina where a landslide has left a dam in “imminent danger” of collapsing. Authorities have ordered residents to flee the area south of the Lake Tahoma Dam, which they say could fail after heavy rainfall caused a landslide that “compromised” its structural integrity. The National Weather Service tweeted an urgent message: “A landslide has comprised the integrity of Lake Tahoma Dam. MANDATORY EVACUATIONS underway from the Dam at Lake Shore Dr to Lake Tahoma Rd (NC 80) to the confluence of the Catawba River near Resistoflex Rd and Riverside Park. ACT NOW TO PRESERVE YOUR LIFE!” The heavy rainfall is part of the remnants of Alberto, the first named storm of the Atlantic hurricane season.
