Abstract: A rain gauge assembly has a collection cylinder situated within a vertical support housing. The lowermost portion of the collection cylinder comes to a point which rests upon the bottommost surface of the support housing. The uppermost portion of the collection cylinder is supported by the uppermost portion of the support housing. Connected to the uppermost portion of the collection cylinder is a flexible connector which is connected to a collector and a collector funnel. Affixed to the collector is a wind deflector support arm. The wind deflector support arm is attached to a vertical deflecting fin and a horizontal deflecting fin. The vertical and horizontal fins are situated in perpendicular planes for reacting to both wind direction and wind velocity, respectively.
