How the ‘Clean Air Force' keeps the skies above Austin clean and healthy
AUSTIN (KXAN) — The Clean Air Force of Central Texas has as its primary goal to keep air in this area clean and healthy. The CAF has been doing this good work since 1994.
Jim Stephens is the executive director of the Clean Air Force. He speaks with Rich Segal about the difference between attainment and compliance, specifically how you try to attain clean air goals to be in compliance with the standards set by the United States Environmental Protection Agency.
Where does Austin stand when it comes to compliance? The short answer is that Austin is not in compliance. That happened in February 2024 when the EPA strengthened the National Ambient Air Quality Standards for Particulate Matter from 12 micrograms (a unit of mass equal to one millionth of a gram) of particulate matter to 9 micrograms.
Austin was in compliance before the change from 12 to 9 micrograms as this area's air quality was/is 9.3 micrograms.
The EPA's goal in making the change was to protect millions of Americans from harmful and costly health impacts.
While Austin is not compliance (but not by much), the EPA is giving Austin (and any other area of the country) two years to work towards getting that 9.3 figure down to below 9. So, there's time.
In their conversation, Jim will tell you the months where this area's Ozone season is the worst and the criteria for an Ozone Action Day declaration.
He also says area citizens can sign up to get email alerts when those Ozone Action Days are going to be in effect. They are usually called for 24 hours in advance.

Summer Is Coming And So Are The Mosquitoes: Here Are Some Of The Best Ways To Protect Yourself
If you've been chomping at the bit to get outside and enjoy the longer days of summer, don't let mosquitoes kill your buzz. The warming temperatures and rising humidity that come with the season likely mean mosquitoes are hatching in your backyard right now. Heavy rain across some parts of the country also increases that likelihood. As senior digital meteorologist Chris Dolce points out: "Much of the South and East have endured a wetter than average May, with abundant rainfall surpluses." As of May 29, the month ranked as the second-wettest May in Birmingham, Alabama; the 13th-wettest in Atlanta and the fifth-wettest in Boston. So if you're trying to largely avoid pesticides and insecticides, here are some of the best ways to eliminate and avoid mosquitoes. Your first layer of protection is insect repellent, so we turned to Consumer Reports for their expertise. They've rigorously tested dozens of repellents and have ranked 59 of them based on their effectiveness. Consumer Reports' Senior Health Reporter Kevin Loria recommends that you look for repellents that use EPA-registered ingredients. Among the ones they tested, those with DEET performed best. If you're looking for a plant-based alternative, he says sprays with OLE – oil of lemon eucalyptus – were also effective. Loria notes that OLE is also less likely to damage fabrics. While you might have seen recommendations or online recipes for homemade repellents using essential oils like peppermint, Loria says Consumer Reports testing showed those are only effective for a very short time – 30 minutes to an hour. Repellents with DEET can last six to eight hours, so that can eliminate the need to reapply. Pro tip: If you need to apply both sunscreen and bug repellent, both Loria and the CDC recommend applying sunscreen first and then insect repellent. Standing water is a breeding haven for mosquitoes, so scour your outdoor spaces for items that may be working against you – from toys and dog bowls, to plant pot saucers, bird baths and your trash containers. You want to turn over, empty, throw out or clean those containers regularly throughout the summer. Loria said dumping out sources of standing water every one to two weeks can do a good job of interrupting and stopping the breeding cycle of mosquitoes in your yard. If you have a swimming pool, make sure to maintain proper chlorine levels and clean the filters and pumps so there's no buildup of organic matter that can attract mosquitoes. (MORE: How To Build A Mosquito Kill Bucket) Let's stay in the backyard and talk about how plants can hinder and help you. First, you want to trim overgrown hedges, bushes and other plants. They can be a good resting and hiding place for mosquitoes. You'll also want to keep your lawn in check by mowing it regularly, but don't forget to clean up the clippings, as those can hold moisture and attract the flying pests. There are plants you can add to your garden that are natural mosquito repellents. As a bonus, they'll look and smell good in your garden. Some good options include: Lemongrass Lemon Eucalyptus Lavender Mint Rosemary Marigolds Citronella Basil Sage Taking a walk or exercising outdoors at dusk or dawn may be a way to beat the most intense heat of the day, but those times are like happy hour for some mosquito species. That can vary by where you live, so pay attention and either avoid being outdoors at those times or layer on the repellent. Here's something else you should note: Getting sweaty and dirty can also make you more attractive to the insects. "When we're out and about and we're moving around, we're exhaling carbon dioxide, and that helps attract mosquitoes," said Loria. Ever notice that you see fewer mosquitoes on breezy days? The insects find it difficult to fly in strong winds, so installing an outdoor fan on your patio or just bringing your box or standing fan out to the porch is not only a great way to stay cool, but it can fend off the bugs.

Americans' Electric Bills Are Headed Higher With the Temperatures
Americans can expect to pay more to stay cool this summer thanks to forecasts for above-average temperatures across the country and natural-gas prices that are heading into air-conditioning season 37% higher than last year. On average, Americans should count on their electricity bills in June, July and August rising 4% from last year, mostly due to more expensive natural gas, according to the Energy Information Administration. New England—where a dearth of gas pipelines keeps energy prices among the highest in the country—should see the biggest jump in monthly bills, up 6.7% from last year, to about $200.

Severe storms threaten millions in South from Texas to Carolinas
Multiple rounds of severe weather are targeting a large swath of the South this weekend. More than 40 million Americans are in the threat zone through Saturday night, stretching from Texas to the Carolinas.

Earlier Saturday, torrential rain slammed parts of Arkansas, including the Little Rock metro triggering flash flooding. A line of severe thunderstorms is sweeping across parts of the Southeast this afternoon bringing strong wind gusts and several reports of wind damage in northern Mississippi and Alabama. A severe thunderstorm watch is in effect across several states, including Birmingham, Alabama, and Atlanta into the evening hours. Tornadoes in Texas, Oklahoma earlier The potential severe weather comes after at least nine tornadoes were reported Friday across Texas and Oklahoma. Grapefruit-size hail was reported near Briscoe, Texas, with hail bigger than the size of baseballs reported elsewhere across Texas, Oklahoma, and Colorado. Winds up to 90 mph were reported from a weather station from storms near Lora, Texas, on Friday, with winds greater than 70 mph reported from other storms in Texas and Oklahoma. Storm threat continues Sunday On Sunday, many of the same areas impacted by storms over the past 24 hours will be in the severe weather threat zone once again. Damaging wind gusts, large hail and isolated tornadoes are also possible then. A level 4 out of 5 severe weather threat -- indicating a "moderate risk" has now been issued for portions of southern Oklahoma and northern Texas, including Lawton, Oklahoma and Wichita Falls, Texas. These areas have the greatest risk of seeing very large hail and destructive wind gusts. Numerous severe thunderstorms are possible for areas highlighted in orange above, under a level 3 out of 5 severe weather threat, indicating an "enhanced risk." Very large hail and destructive wind gusts could impact these locations as well, which includes Oklahoma City and Dallas. The threat of severe weather will persist across parts of the South into Monday as well, with Louisiana to South Carolina currently in the threat zone for another round of strong thunderstorms.
