Oceanside Spending $7 Million to Improve Downtown Storm Drainage

Oceanside is preparing to launch a $7 million upgrade of its downtown storm drain system to prevent seasonal flooding, but the California Coastal Commission has raised concerns about the plan.

City officials met with the Coastal Commission staff Aug. 24 to discuss a possible 90-day extension of the city’s application for a coastal development permit needed for the project.

‘Weather Whiplash’ Withers, then Drowns Areas Worldwide

The Dallas area is still reeling from record-breaking downpours that triggered flash floods across northeastern Texas last week. The event swamped houses, submerged vehicles and prompted hundreds of emergency rescues. At least one death has been reported so far.

The sheer volume of rain was stunning, with some locations receiving more than a foot. But the deluge was all the more surprising because Dallas has been choked by severe drought for months.

Weather Whiplash: Summer Lurches From Drought to Flood

Parts of northern Texas, mired in a drought labeled as extreme and exceptional, are flooding under torrential rain. In a drought.

Sound familiar? It should. The Dallas region is just the latest drought-suffering-but-flooded locale during a summer of extreme weather whiplash, likely goosed by human-caused climate change, scientists say. Parts of the world are lurching from drought to deluge.

Better Atmospheric River Forecasts Are Giving Emergency Planners More Time to Prepare for Flooding

I was eating breakfast on a Monday morning at Sears Fine Food in downtown San Francisco, casually watching the local five-day weather forecast on a television screen behind the counter. A little symbol along the bottom showed a happy-looking sun for the rest of the day. Wednesday had a friendly-looking cloud and a few raindrops, and Thursday had a dark, threatening cloud with heavier drops.

I knew Thursday’s conditions would be much rougher than the symbol conveyed. I had been studying detailed satellite data and weather models, and they indicated that a major atmospheric river (AR) was likely to hit the city. The symbol was completely inadequate for communicating the threat of the approaching storm.

 

How Can Imperial Beach Residents Participate in Solutions Against Flooding? This Group Wants to Help

Every year, Imperial Beach residents board up their windows and shovel ocean sand off streets left underwater during high tide.

Researchers have been testing technology that warns the city in time to prepare for the arrival of powerful waves and, most recently, digging groundwater wells to track flooding.

The community can also play a significant role in reducing Imperial Beach’s flooding problems, researchers at San Diego State University said last week. How residents can get involved is what the researchers are hoping to find out.

Decades of Flooding in Leucadia Raise Drainage, Legal Questions

Jeff, a Leucadia resident who lives on Basil Street, said it was in 2001 when his home first flooded. “It was two weeks after I moved in, and I had just painted the house and put in new carpeting, so it really wasn’t good timing,” Jeff recalled with a laugh, noting his home would flood again four years later. But for Jeff and his neighbors who live along North Coast Highway 101 in Leucadia, the issue of flooding in Leucadia has been no laughing matter.

California’s Climate Whiplash Has Gotten Worse Over 50 Years

While dry events in California are not getting drier, extreme wet weather events have steadily increased in magnitude since the middle of the last century, new research shows.

These increased extreme wet events can result in more dangerous flooding and also fuel wildfires.

“Most research after 2015 has been very focused on this climate variability and how it’s going to get worse in the future,” says Diana Zamora-Reyes, a graduate student in the department of hydrology and atmospheric sciences at the University of Arizona and lead author of the paper in the International Journal of Climatology.

Soaking Rain Could challenge Records in LA, San Diego on Christmas Eve

A potent storm that took aim at the Northwest earlier in the week will drop down into California on Wednesday, setting the region up to receive drought-relieving rain and snow — and the rainfall could set records on Christmas Eve.

Increasing amounts of moisture will move onshore on Wednesday, and snow is anticipated to develop across the Sierra Nevada mountain range. This will be the beginning of an extended stretch of wet weather for the Southwest, according to AccuWeather Lead Long-Range Meteorologist Paul Pastelok.

By Wednesday night, heavy rain will drench the California coast as well as the southwestern edge of the Sierra Nevada. San Francisco and San Jose, California, are just two of the cities that will receive needed precipitation. Heavy snow is expected to begin across the Sierra Nevada as well as parts of the Klamath Mountains.

Record-Shattering Rain Pummels Bay Area, Lingering Showers Continue Into Tuesday

A robust atmospheric river storm started to taper off Tuesday morning in the Bay Area after shuttering highways due to flooding and prompting evacuation warnings in areas left scarred by wildfires and susceptible to mudslides and debris flows.

Researchers Work to Keep Imperial Beach Above Water

Every winter, Imperial Beach finds some of its streets and sidewalks underwater. This week, researchers from San Diego State and UC San Diego started digging groundwater wells to see how sea-level rise plays a role in that flooding. The sea-level impacts how shallow the water table is underneath the city.

“Flooding overall is a very, very big thing in Imperial Beach,” said Hassan Davani, Ph.D.

The SDSU researcher said most studies predict sea-level rise will significantly impact California as early as 2050. However, Davani said Imperial Beach can’t wait that long to protect itself.
