Increasing moisture is leading to a better chance of Thunderstorms over Frisco and the rest of Summit County.

Hot, with a good chance for late-afternoon and evening showers in the high country; learn what the top ten lightning myths are

By Bob Berwyn

SUMMIT COUNTY — A better chance for thunderstorms in the Colorado high country today with mid-level moisture predicted to stay in place over the mountains through tonight. As a result, the National Weather Service is forecasting widely scattered thunderstorms and showers for Tuesday afternoon.

During the next few days, an area of low pressure will move into the northern Great Basin, with counterclockwise flow out of the southwest bringing more moisture to the area in what looks to be the start of a monsoon pattern. That will help keep a chance for showers in the forecast the next few days, although the moisture is still somewhat limited. Right now, the forecast is for slightly cooler temperatures, in the high 60s, and drier weather for late in the week.

By 1 p.m. the temperature in Dillon reached 72 degrees and could climb a few degrees higher under clear skies. Kremmling, at a lower elevation, registered an 81-degree reading at 1 p.m. The record June 29 high for Frisco is 83 edges, set in 1961, while the record low temperature is 24 degrees, set in 1945. With a bit more moisture in the area and some thin nighttime clouds, overnight lows stayed a bit above average Monday, with none of the official weather stations recording sub-freezing temperatures. Leadville was the cold spot, at 36 degrees.

Temperatures across the West Slope will remain hot, reaching 100 degrees in Moab and 97 in Grand Junction, and into the mid-80s around Aspen and — but not as hot as Death Valley, where the high Monday reached 123 degrees, a typical summertime reading. Stanley, Idaho was the icebox of the nation, at 31 degrees.

Top ten lightning myths

1.    MYTH: Lightning Never Strikes The Same Place Twice
TRUTH: Lightning often strikes the same place repeatedly, especially if it’s a tall pointy isolated object. The Empire State Building used to be used as a lightning laboratory, since it is hit nearly 25 times a year. Places prone to lightning are places to avoid when thunderstorms are nearby!

2.    MYTH: If It’s Not Raining, Or If Clouds Aren’t Overhead, I’m Safe From Lightning
TRUTH: Lightning often strikes more than three miles from the thunderstorm, far outside the rain or even thunderstorm cloud. ‘Bolts From The Blue’, though infrequent, can strike 10-15 Miles from the thunderstorm. Anvil lightning can strike the ground over 50 Miles from the thunderstorm, under extreme conditions. Lightning in clouds has traveled over 100 miles from the thunderstorm.

3.    MYTH: Rubber Tires Protect You From Lightning In A Car By Insulating You From The Ground
TRUTH: Lightning laughs at two inches of rubber! Most cars are reasonably safe from lightning. But it’s the metal roof and metal sides that protect you, not the rubber tires. Thus convertibles, motorcycles, bicycles, open shelled outdoor recreational vehicles, and cars with plastic or fiberglass shells offer no lightning protection. Likewise, farm and construction vehicles with open cockpits offer no lightning protection. But closed cockpits with metal roof and sides are safer than going outside. And don’t even ask about sneakers!

4.    MYTH: A Lightning Victim Is Electrified. If You Touch Them, You’ll Be Electrocuted.
TRUTH: The human body doesn’t store electricity. It is perfectly safe to touch a lightning victim to give them first aid. This is the most chilling of lightning myths. Imagine someone dying needlessly, for want of simple CPR or mouth-to-mouth resuscitation, when their chance of survival was 90 percent.

5.    MYTH: If Outside In A Thunderstorm, Go Under A Tree To Stay Dry
TRUTH: Being underneath trees is the second leading activity for lightning casualties —  enough said!

6.    MYTH: I’m In A House, I’m Safe From Lightning
TRUTH: While a house is a good place for lightning safety, just going inside isn’t enough. You must avoid any conducting path leading outside, such as corded telephones, electrical appliances, wires, TV cables, plumbing (including plastic pipes with water in them), metal doors or window frames, etc. Don’t stand near a window to watch the lightning. An inside room is generally best.

7.    MYTH: When Playing Sports And Thunderstorms Threaten, It’s Okay To Finish The Game Before Seeking Shelter
TRUTH: Sports is the activity with the fastest rising rate of lightning casualties. No game is worth death or life-long severe injury. All people associated with sports should have a lightning safety plan and stick to it strictly. Seek proper shelter immediately when lightning threatens. Adults are responsible for the safety of children.

8.    MYTH: Structures With Metal, Or Metal On The Body (Jewelry, Watches, Glasses, Backpacks, Etc.), Attract Lightning
TRUTH: Height, pointy shape, and isolation are the dominant factors controlling where a lightning bolt will strike. The presence of metal makes virtually no difference on where lightning strikes. Mountains are made of stone, but receive many strikes each year. When lightning threatens, take proper protective action immediately. Don’t waste time shedding metal off your body, or seeking shelter under inadequate structures. But while metal doesn’t attract lightning, touching or being near long metal objects (fences, railings, bleachers, vehicles, etc.) is still unsafe when thunderstorms are nearby. If lightning does happen to hit it, the metal can conduct the electricity a long distance (even over 100 yards) and still electrocute you.

9.    MYTH: If Trapped Outside And Lightning Is About To Strike, Lie Flat On The Ground
TRUTH: This advice is decades out of date. Better advice is to use the ‘Lightning Crouch’: put your feet together, squat low, tuck your head, and cover your ears. Lightning induces electric currents along the top of the ground that can be deadly over 100 Feet away. While lying flat on the ground gets you as low as possible, which is good, it increases your chance of being hit by a ground current, which is bad. The best combination of being low and touching the ground as little as possible is the ‘Lightning Crouch’. But the ‘Lightning Crouch’ should be used only as a last resort. Much better would be to plan outdoor activities around the weather to avoid thunderstorm exposure and to have proper shelter available.

10. MYTH: Go near a tall pointy isolated object when thunderstorms threaten, to be within the 45 degree “cone of protection”
TRUTH: The “cone of protection” is a myth. While tall pointy isolated objects are statistically more likely to be struck by lightning, it’s not nearly reliable enough to rely on for safety. Lightning can still strike you near the tall object. Besides, the lightning electricity will likely spread out along the surface of the ground and can still kill you more than 100 feet from the “protecting” object. Also, if you are close to, or touching, the tall object, you can be electrocuted via side flash or contact voltage.

NO PLACE OUTSIDE IS SAFE NEAR A THUNDERSTORM. In lightning safety, a “myth” is not as good as a mile. Distance and proper shelter are your best protection from lightning.
