As most people know, spring and summer storms are unpredictable. While weather forecasters can tell you the chance of rain or show you radar, those storms could take a turn and become a lot worse as they head for your party, without you realizing it. If you're holding an event outdoors and are using a party tent, you can't just schedule the event for a time when you think there won't be storms — you have to prepare the tent and your guests just in case.
