Roll for weather during the Weather Determination Segment.
17.0a Weather affects play according to the effects (if any) listed with the game- specific Weather Table.
17.0b Weather generally affects each player equally (in some games it can affect one side or the other differently).
17.0c Weather conditions that increase the normal movement costs are ignored when tracing supply paths (12.3d).
17.0d In a change to some older game rules, weather can never prohibit refit, or prevent aircraft from being Active at their base.
