It’s best to stay indoors during a rainstorm, if only to keep yourself dry and comfortable. This is a great time for books and family games. If you hear thunder outside, consider unplugging your TV, computers and gaming gear, as a lightning strike could cause a damaging surge of electricity in the power lines. You may also want to avoid using water, as this can contribute to overwhelming your drainage system. And you may want to do periodic checks in your basement and around your windows and doors for any incoming water. That way you can quickly mop up any water getting into your house and prevent further damage, including the growth of mold.
