Severe weather myths debunked

Myths and Facts about weather

Many myths surround severe weather and Meteorologist McCall Vrydaghs and Kirstie Zontini wanted to debunk a few.

>>LIVE INTERACTIVE RADAR 

  • Myth 1: Lightning never strikes when the skies are clear. 

This is a common myth associated with storms. It is false though because lightning can strike 10 to 15 miles away from a parent storm. These strikes are called “bolts from the blue.” If you hear thunder go inside.  

  • Myth 2: It’s safe to drive a truck through floodwaters. 

This is also false. Water over the roads can actually be hiding deeper spots in the road like a sinkhole which can be dangerous even in a truck. Also, it only takes about 2 feet of rushing water to wash away a car. 

  • Myth 3: Small sized hail isn’t dangerous.

This is actually not true! A thunderstorm with strong winds can make any sized hail dangerous.  

  • Myth 4: Cities are safe from tornadoes. 
This is a big myth. Tornadoes can develop anywhere. Big cities like Dallas, Salt Lake City and Miami have all had reported tornadoes. An urban environment will also have more debris to throw around as well.

Great American Eclipse: How to spot fake glasses, handheld viewers

Published: Friday, July 28, 2017 @ 11:04 PM

Meteorologist McCall Vrydaghs and Meteorologist Kirstie Zontini explain how to make a solar eclipse pinhole projector with items you have around the house.

The Great American Eclipse will be an amazing sight to see Aug. 21 when it crosses the country coast to coast — the first time since 1918.

Locally the eclipse won’t be total, but 90 percent, according to the Storm Center 7 meteorologist team.

Viewing the total solar eclipse requires specific eclipse glasses or handheld solar viewers, not regular sunglasses.

It’s dangerous to look directly at the sun, especially during an eclipse without adequate eye protection.

WATCH: When will the solar eclipse be visible in your community?

"Even the tiniest sliver of a crescent sun peeking out from behind the moon emits enough light to scorch your eyes,” Ralph Chou, professor of optometry and vision science at the University of Waterloo in Canada told Space.com

Chou said about half of patients diagnosed with eclipse blindness regain full vision in six months. But the other half partially or never recover, he said.

But how do you avoid getting scammed, and potentially blinded, by knockoff eclipse glasses targeting unsuspecting consumers? 

NASA gives advice on what to look for before buying eclipse viewing glasses and handheld solar viewers. Safe glasses, solar viewers must meet all the following criteria:

  • Certification information with a designated ISO 12312-2 international standard 
  • The manufacturer's name and address printed somewhere on the product 
  • Do not use if it’s older than three years or lenses have tears, scratches or wrinkles
  • Do not use homemade filters or regular sunglasses, even dark ones 

Leading up to the Great American Eclipse next month, the marketplace is being flooded by counterfeit glasses, which can falsely advertise they meet the international standard.

How do you know which manufacturers make safe eclipse glasses and solar viewers?

NASA and the American Astronomical Society said there are five manufacturers that meet the international standard to look directly at the sun.

They are:

  • American Paper Optics
  • Baader Planetarium (AstroSolar Silver/Gold film only)
  • Rainbow Symphony
  • Thousand Oaks Optica
  • TSE 17 

Approved retail chains selling certified glasses are

  • Best Buy 
  • Bi-Mart 
  • Casey's General Store 
  • Hobby Town 
  • Kirklands 
  • Kroger 
  • Lowe's 
  • Maverik
  • 7-Eleven
  • Pilot/Flying J 
  • Walmart

NASA also recommends that whatever recommended safety device you use, give your eyes a few breaks and do not stare continuously at the sun. Keep your special glasses on throughout the eclipse.

Where can you find solar eclipse glasses or solar viewers?

You can purchase the glasses on the manufacturer’s websites or through online retailers. Or, you might be able to find a free pair from your local library. Check your library to find out availability. 

You can keep for solar eclipse glasses for the next eclipse event in 2024, as long as they haven’t been damaged.

Looking towards a hot and humid day for the solar eclipse across the Miami Valley

The viewing will begin around 1 p.m. with the max eclipse around 2:28 p.m. This means plenty of people will be outside during the peak heating hours of the day.

Make sure you DO NOT look directly at the sun even for a few seconds unless you have ISO compliant solar eclipse glasses.

RELATED: Can’t find eclipse glasses? Here are some other options

The day will warm up quickly with most of the eclipse time-frame in the mid to upper 80s. Dew points will be in the 60s so it will feel muggy as well. 

Heat index values can reach the low 90s that day so please make sure you have plenty of water to stay hydrated and take breaks outside if you feel like you are overheating. 

There will be a good deal of sunshine especially early but as the day goes on some high clouds and a few fair weather clouds look to develop. We are lucky that the forecast will stay dry to enjoy the show!
