Does anybody know a good, effective rain cover to protect the plane in those fields where there is not a roof to wait until the rain stops?

I'm practicing at a new place with very similar alttitude to the worlds, but it is a pretty raw place (just a grass runway and that's it, see a couple of pictures below. It is in Medellin, Colombia) .I'd like to protect the plane during the rainfall while I wait in the car.

Thank you!
