Inches/year means nothing for 55-85 GHz links... Seattle gets a ton of rain and some coastal areas or places where the clouds are trapped by mountains a lot more (Lynn Valley, North Vancouver BC for example). But all are only in rain zone D. It's the frequency of instances of certain figure, N, where N is your millimeters/hour peak rain rate that matters. Water drop density in mm/hour is what will take out a millimeter wave link, or cause serious modulation changes on 11/18/23 GHz.
Constant drizzle that adds up to 60 inches/year or more can still be in rain zones C, D or E.
