This is a <br />phenomenon due to an orographic barrier such as Tenmile Range <br />removing the moisture from the air on the windward side (Cli- <br />max II) and thus reducing the precipitation on the leeward side <br />(Hot Sulphur Spring). The upper mue River Basin is in such a <br />rainshadow, being directly east of the Tenmi1e Range. <br /> <br />The facts presented above lead one to the conclusion that <br />the most likely synoptic formation occurring during the summer <br />months for a 100-year event is a convective storm, namely, a <br />cumulonimbus cloud system. <br />
