I recently wrote a piece for Style that offers advice about the weather for those planning an outdoor wedding. My most important words of wisdom: develop a back-up plan in case the weather goes bad. Here’s an excerpt:

Keep reading and watching to understand the consequences of not following this advice...

A tornado siren may sound

After the gentleman officiating the wedding asks “if there is anyone here who has just cause why this couple should not joined in holy matrimony, speak now or forever hold your piece”, right on cue, the tornado siren sounds. Not the best omen.

A tornado may strike

The only thing worse than a tornado siren during your wedding is an actual tornado. In this video, the reception in Crown Point, Indiana is wrecked by a twister on June 4, 2011.

Winds may take out your tent

A violent thunderstorm forces wedding guests to try to hold up a collapsing tent (caution, strong language)

You may get sand blasted

Remember the sandstorm or haboob that wreaked havoc in Phoenix last July? This couple remained remarkedly composed when this onslaught of sand interrupted their ceremony.

A wave may flood you and your guests

Even if you end up with a sunny day for your beach wedding, be sure you set up your ceremony far enough away from the surf! This couple learned that lesson the hard way...
