What do all the heat warnings, advisories, and watches mean?

The calculation of the heat index triggers all the warnings, watches and advisories. It's a measure of air temperature and relative humidity.

Heat and sun cook up pollution today, close schools

Temperatures across the southern part of the state are expected to be in the mid to upper 90s today.

In addition to heat related stress, the hot weather can also lead to more pollution.

The weather has led the Michigan Department of Environmental Quality to post "ozone action days" for several cities in the southern part of the state including Ann Arbor, Benton Harbor, Detroit, Kalamazoo, Grand Rapids and Ludington.

Smokestack and tailpipe emissions and vapors from gas and chemicals can be turned into ozone pollution on days like today. People are urged to drive less, refrain from using gas-powered lawn equipment, and refuel cars and equipment at a later time.

Ozone pollution can cause chest pain, coughing, throat irritation, and congestion, and it can worsen bronchitis, emphysema, and asthma.

The Detroit News reports that several schools in Detroit will be closed because of a lack of air conditioning in those buildings.

Grayling Wildfires contained

Wildfires burned near Grayling yesterday. Now state officials say the blaze has been contained. From the Associated Press:

A state spokeswoman says fire crews have fully contained a blaze that burned 750 to 800 acres of northern Michigan woodlands, destroyed or damaged a number of buildings and forced the evacuation of 100 homes.

Mary Dettloff is a spokeswoman for the Michigan Department of Natural Resources. She tells The Associated Press Wednesday morning that the fire was 100 percent contained by midnight Tuesday and people who had been evacuated were permitted to return home.

Riders go to Lansing to support repeal of helmet law

Michigan is one of twenty states with a motorcycle helmet law.

Advocates of repealing the law have been successful in the past at getting the legislature to pass repeals of the helmet law, but they ran into vetoes from former Governor Jennifer Granholm.

Now they're hoping Governor Snyder will be on their side.

Motorcycle riders are expected to hold a rally in Lansing today supporting a helmet law repeal.

MPRN's Rick Pluta spoke with a helmet law repeal advocate who said Michigan is losing out on a lot of tourism opportunities as riders avoid Michigan: 

"Every state surrounding Michigan allows adult choice and people do not come from those states to Michigan simply because we have a mandatory helmet law," said Jim Rhoades.

Supporters of the helmet law say it cuts down on medical costs that are often passed onto others. The Detroit Free Press reports :

Many medical and insurance organizations are lobbying to keep the current law, which they say reduces serious injuries and deaths in motorcycle accidents. Medical costs for riders injured without helmets are four times costlier than for those injured while wearing helmets, says the National Transportation Safety Board.

Governor Snyder has not taken a side on this issue, but the Free Press reports Snyder "has said he would support the change if other motorists didn't pay more as a result."

Pollution levels high, Ozone Action Days declared in Michigan

SEMCOG says the Ozone Action Day is the earliest one called since 1999.

The sun and heat cooks up the pollution in Michigan.

The Michigan Department of Environmental Quality says an "Ozone Action Day" has been declared in four Michigan cities today:

  • Benton Harbor
  • Kalamazoo
  • Grand Rapids
  • Ludington

And tomorrow, six cities will be have Ozone Action Days, as the heat is expected to stay with us.

  • Ann Arbor
  • Benton Harbor
  • Detroit
  • Kalamazoo
  • Grand Rapids
  • Ludington

Ground-level ozone pollution is formed on hot, sunny days when emissions from cars and trucks, industrial smokestacks, and vapors from gas and other chemicals are cooked into "bad" ozone.

The EPA says the pollution can have serious health and environmental impacts:

Breathing ozone, a primary component of smog, can trigger a variety of health problems including chest pain, coughing, throat irritation, and congestion. It can worsen bronchitis, emphysema, and asthma. Ground-level ozone also can reduce lung function and inflame the linings of the lungs. Repeated exposure may permanently scar lung tissue.

Ground-level ozone also damages vegetation and ecosystems. In the United States alone, ozone is responsible for an estimated $500 million in reduced crop production each year.

We're supposed to take action on an Ozone Action Day. The Southeast Michigan Council of Governments offers these tips on what to do when an Action Day is declared in your area:

  • Avoid refueling your vehicle. If you must refuel, fill up as late in the day as possible, preferably in the evening when the weather is cooler. Fumes released at the gas pump contribute to ozone formation.
  • Delay mowing your lawn. Emissions from your lawn mower help form ozone.
  • If you plan to barbeque, avoid using lighter fluid. Emissions from the fluid contribute to ozone formation.
  • Take the bus, carpool, bike or walk. You'll reduce traffic congestion and air pollution as well as save money.
