At least 190 people are known to have died as a result of the carnage and destruction wrought by Hurricane Helene since it made landfall in Florida a week ago.

Helene made landfall in Florida's Big Bend region Thursday night as a massive Category 4 hurricane -- the strongest hurricane to make landfall in the Big Bend on record.

TVA's system of dams along the Tennessee River and its tributaries has been tested by record flooding from Hurricane Helene, which drenched Western North Carolina and East Tennessee as a tropical storm , washing out interstate lanes and trapping residents as small streams in the Great Smoky Mountains suddenly became raging rivers.
