Although it's fairly well documented on here and elsewhere that Tesla won't replace them with water damage cos they don't consider them weatherproof or waterproof... I know plenty of people on forums and Facebook claimed to have theirs out in all weather for months or years, which is great, until it isn't. In a pinch I'd shelter under the car raised off the ground with a rock or brick. Like the poster above though I've bought a large Dribox for mine to sit in if/when needed (which is only in genuine emergency). Yes, I know that in turn probably raises a whole other debate about heat dissipation...
