What feelings does banquo express to fleance and what mood do these create?

Banquo expresses to Fleance that there is trouble brewing, and that he should be careful and on guard. He says "there's husbandry in heaven" (meaning that the stars aren't showing and that signifies something bad going on) and gives Fleance a sword. This creates a mood of fear and tension.
