Masks are…

…not effective in a hurricane OR a tornado, which is what we are facing on the east coast today. If you are wearing a mask, as you have been, because of the pandemic then first I applaud you. Second, go back inside because there is a hurricane with the chance tornado!
If you stay out and your mask gets wet; including the tiniest of droplets, then that mask has become useless and you might as well go back inside.
If you have no choice but to go out and perform your duties as a (wo)man of essentiality (like maybe you have to tow a truck or deliver a pizza), then I applaud you once again because not all superheros wear capes.
