When Thunder Roars, Go Indoors: Severe Weather Awareness Week Highlights Lightning, Hail Danger

(KNSI) — Severe thunderstorms, lightning and hail are the focus for Tuesday during Severe Weather Awareness Week. National Weather Service warning coordination specialist Todd Krause says it’s a good idea to remember the rhyme: when thunder roars, go indoors. “Lightning creates thunder. So, if you’re hearing thunder, then by definition, there’s lightning. So, getting inside for any thunderstorm is important.”

Lightning can strike as far out as ten miles from the base of a thunderstorm. “It doesn’t have to be raining where you are for you to get struck by lightning. So, if you hear that thunder, you’re close enough to be in the lightning hazard area.”

Another rule to remember is 30-30. When lightning flashes, count the time until the thunder. If it’s 30 seconds or less, stay inside, then wait 30 minutes after the last rumble to go back out.

Krause warns about the other danger of large hail. “I think we’ve had a few reports over the years of hail five inches in diameter, that’s a little bit larger than softballs. And, you know, I certainly wouldn’t want to be outside and struck by a hailstone that large.”

Damaging winds can also carry debris, which could pose a danger to those standing outside.

Krause says to have a way to get watches and warnings if you have outdoor plans and craft alternate plans in case of severe weather.
