Currently in Los Angeles — October 14th, 2022

The weather, currently.

Fingers crossed for a rainy weekend in Los Angeles!

What’s that I see? A rainy weekend in Los Angeles? Is my mind playing tricks on me?

I blink and rub my eyes, correcting my sleepy vision, but the forecast remains the same. Friday and Saturday are showing rainfall, and though the chances aren’t fantastic (nothing higher than 40%,) we got unlikely rain the other night, so I’m going to believe we’ll get it again.

Dodgers Goose has nothing to do with the forecast, but I loved them and wanted to share!

Friday begins with a marine layer and sunshine. Highs of 78°F are perfect for our version of fall. It’s not until we head into the evening that the chance of thunderstorms appears, adding rage to the marine layer. A relatively warm low of 64°F, brought to you by humidity, will bring some static to the sky. If we don’t get the storms, Saturday gives us another chance of rain. It’ll be gray and overcast all day, and hopefully with showers accompanying the moody skies. Highs will be noticeably lower, close to 72°F, so you’ll want a jacket on hand even if you’re not getting wet. Lows will plunge into the 50’s.

Saturday’s cool weather will bleed into Sunday, but by then the skies will be dry. We’ll have more marine layer and cloud coverage, but it’s all empty threats. Highs and lows will match Saturday’s, with a mild high around 73°F and low temperatures falling all the way down to 57°F late at night.

One of the more insidious byproducts of sea level rise is the way it will affect groundwater. A new study, that was presented at the Geological Society of America yesterday, found that North Carolina’s septic systems were particularly vulnerable. As groundwater rises, bacteria and waste will rise to the surface — mingling with drinking water and backing up into residents’ houses.

As climate change increases the probability of extreme precipitation, even inland sewer systems will be at risk. Philadelphia, for example, has a combined sewer system that transports both storm runoff and wastewater and leaves it vulnerable to flooding during extreme rainfall events like the remnants of Hurricane Ida that hit the Northeast last year. The UN estimates that only 48 percent of sewage systems worldwide adequately treat wastewater and climate change will complicate things, even for well-functioning systems.

The study focused on Nags Head, North Carolina and found that homes that were less than 2.6 meters above sea level were significantly more likely to have trouble. Part of the issue is regulatory — although the insurance industry is beginning to catch up to rising seas, rising groundwater further inland is often overlooked and regulations are outdated.

“Homeowners need to get their systems inspected and pumped every three to five years, depending on how many people live in the home,” Mary Lusk, an assistant professor at the University of Florida, told the Apopka Voice. “This will help keep the system working at its best even during heavy storms or other disasters. But if you see waste backing up in the toilet or bathtub, or if the area around your septic system stinks, that’s a sign that it’s not working correctly, and you should call a professional septic system inspector right away.”
