Query: water gets inside

I love grilling and was happy to go for the grill cover that matches my grill brand, but I feel this cover is lighter then the last one I had on my old grill. The other thing and the bigger issue is that I have found water underneath the top of the cover after a rain storm, which scares me because my Grill is a brand new Weber which I am very happy with. It may rust quickly due to water getting under the cover.
