We hope everyone brought his or her umbrella to work today, and we hope that it’s one of those doesn’t-turn-inside-out-in-the-wind ones, because we’re about to receive a severe lashing from thunderstorms this afternoon. If this radar shot, and the National Weather Services’ severe thunderstorm warning (on until 8 p.m. tonight) are any indicator—which they are—we’ll be in for a dazzling lightshow starting anywhere from now until 7 p.m.

Since the warm weather we’ve been having will produce many more electrical storms in the near future, we thought we’d share these handy reminders from ABC News about what to do in a severe lightning situation.

• Remember the 30-second rule. If there are fewer than 30 seconds between thunder and lightning striking, it’s time to get indoors.
• When inside your home, don’t talk on a corded phone. If lightning strikes your house, it can travel through the phone lines, through the phone cord and into your ear. Most lightning deaths that occur inside the home happen because people are talking on the phone at the time of the strike.
• If you must remain outdoors and you’re with a group of people, separate instead of huddling together. If you remain in a clump, that gives the electrical current lots of bodies to run through if you’re hit.
• Still outside? Crouch down close to the ground with your feet touching together. That way even if lightning strikes 100 feet away, the current will come up through one foot and back down the other and won’t travel through your body and won’t harm vital organs.

Remember kids, lightning is dangerous and no laughing matter. Unless you’re this woman. Then it’s still seriously dangerous but c’mon, a little bit funny.
