Weather in and around Mississippi is about to get really bad

Over today and especially tommorow there is supposed to be really bad weather here, possibly f4 or higher tornados. It's supposed to be as bad as some weather from 2011 from what I've heard. Pray that everyone will be alright and safe from the weather. My family is near the center I am pretty sure but we have a shelter so we should be fine if the shelter doesn't get blown away. Thanks.
