My rainfall totals for my week and month delete after every day. They usually don't tally up in a normal fashion either. I got this weather station to keep track of my year since I work in an industry where rainfall amounts matter. I also will get different high wind speeds on myacurite compared to the display. I wish I could say I trust Acurite's equipment, but honestly I am considering switching manufactures. I have the 06058M weather display.
