Poor air quality expected in SoCal this week amid heat wave


LOS ANGELES (KABC) — As another brutal heat wave moves into Southern California, it’s more than just the temperatures impacting local residents.

Poor air quality will also be cause for concern.

“Ozone, or smog, is the dominant summertime pollutant in Southern California. And that tends to form more readily under high temperatures,” said Scott Epstein, planning and rules manager of air quality assessment for the South Coast Air Quality Management District.

The extreme heat increases the amount of ozone pollution in the air which in turn negatively impacts our air quality.

“When temperatures are high you get a lot more evaporation of one of the compounds that form smog in the atmosphere, and you speed up the reactions that form smog as well, so we tend to see our highest ozone levels or smog levels on the hottest days of the year,” added Epstein.

As temperatures climb during the day so do ozone levels, so expect to see the worst air quality in the mid-to-late afternoon. These high levels can trigger breathing issues including asthma.

“Breathing high levels of ozone can cause serious respiratory issues such as asthma. It can aggravate respiratory conditions such as COPD, cause trouble breathing or other lung issues. So the most important thing on these days is to be aware of high levels of ozone. It’s not a visible pollutant,” said Epstein.

When conditions are bad try to minimize bringing what’s outside – inside.

“Keep windows and doors closed, run your air conditioner and air purifier and minimize things that bring outdoor air inside, such as a swamp cooler or a whole-house fan,” added Epstein.

While some groups gathered in downtown Los Angeles to protest the strikes, others assembled in Westwood to celebrate “the fall of the Ayotollah,” according to organizers.

Authorities said they will continue monitoring events as the region prepares for additional gatherings in the days ahead.

Six planets to align in “planetary parade” above California. Here’s how to see it.

Six planets to align in “planetary parade” above California. Here’s how to see it.


A rare celestial event will be taking place in the sky above California on Saturday night, as six planets are expected to be visible in what is being called a “planetary parade.”

Look towards the western horizon 30-60 minutes after sunset. Mercury, Venus, Jupiter, and Saturn will all be lined up along an arc, visible to the naked eye creating a literal parade of planets.

The alignment only occurs every few years, with the next one not until 2028.

Mars, Jupiter, and Saturn are frequently seen in the night sky, but the addition of Venus and Mercury make this planet lineup particularly noteworthy.

In the San Francisco Bay Area, there will be some cloud coverage Saturday evening, but it should be in the high levels of the atmosphere so hopefully the horizon remains clear. In Los Angeles and San Diego, the forecast is expected to be clear.

Meanwhile, the planetary parade may not be visible in the northern part of the state, with cloudy conditions expected Saturday night in Sacramento, and possible showers and thunderstorms in Eureka and Redding.

People with telescopes and binoculars will also be able to see Uranus and Neptune as well.

For amateur astronomers, this also would be a fun time to test out your telescope skills by checking out Jupiter’s many moons or Saturn’s rings.

Please note that if your view is obscured by buildings, trees or hills, you won’t see the parade because it will appear very low on the horizon.

The nontechnical term is Parade of Planets, but the technical term is planetary alignment. Basically, it’s just the name for what happens when the planets and sun line up in the sky, these happen during events called oppositions and conjunctions.

Opposition is the term for when a planet is directly opposite the Earth from the Sun. Meanwhile, conjunction is when they are aligned with each other and is when we get the best views of the planets.
