explain the meaning of the storm that appears in act 1 scene 3 line 33-35

Cassius has been wandering the streets in a storm. When Cassius inquires why he would do this Cassius replies that it is the Gods warnings about a "monstrous state". This is Cassius's excuse to say that the God’s are angry that Caesar is going to be pronounced emperor in the senate. For Cassius the night is also symbolic of a Caesar with complete power; apparently Caesar would be like thunder and lightening all the time! Many of Shakespeare's plays had bad weather before the murder of someone important (ie. Macbeth) traditionally it is a symbol that the natural order of things was about to be disturbed.

OOPS, I ment when Casca asks Cassius....
