What is the meaning of the heavens scowled, the Huskies howled and the winds began to blow

These lines brilliantly depict a bleak scene in the frozen North. "The heavens scowled" suggests the skies were dark and forbidding; "the huskies howled" suggests the eerie sound of the dogs; "the winds began to blow" suggests an approaching storm. All three phrases give the impression that something tragic is about to happen in this cold, Arctic environment.
