Where does thunder come from?
In the Middle Ages church bells were used to expel the evil spirits associated with thunder and lightning. So during a thunderstorm churches constantly rang the bells.
Thunder comes from the flash of a 50,000°F lighting bolt (five times hotter than the sun). The surrounding air of lightning quickly heats and cools in fractions of a second. It’s this rapid expansion and contraction of the air that creates a compression wave we hear as the crackle of thunder.
Nearly 2000 thunderstorms occur at any time around the world with around 40 lightning strikes per second, or 3,500,000 lightning strikes every 24 hours.
You can hear thunder 5 to 12 miles from the starting point and the average length of a single lightning bolt is 2 to 4 miles.
The 30-30 Rule.
According to the National Oceanic and Atmospheric Administration, if you see lightning and hear thunder in under 30 seconds, lightning is close enough to hit you. It also recommends you to wait 30 minutes after a thunderstorm to safely leave your shelter. From weatherimagery.com
Plan for alternative power supplies. Back-up generators work!
Keep lights on when the power is out. Permanent or portable generators can help alleviate power outage issues and enable you to continue living pretty close to normal. This will minimize down time due to power loss.
Learn more about automatic standby natural gas back-up generators for your home or business before the next power outage. PDM had served the Joliet SW Chicago suburbs since 1885.
Worried about power going out or basement flooding during bad weather?
A natural gas automatic back-up generator keeps the lights on in the worst of times. Or add a powerful battery operated sump pump to keep you dry. Call the PDM Clean Team for information and a free estimate. Call 815-726-6264 or 630-378-4488
