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

/in , , /by /The San Diego Union-Tribuneby Tanya Murga

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

/in , /by /The Coast News Groupby Stephen Wyer

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

/in , , /by /Futurityby Mikayla Mace-Arizona

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

/in , , /by /NBC 7 San Diegoby Joe Little

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.

Burst Water Main Floods Freeway, Forces Closure of I-5 Downtown

Drivers heading into downtown San Diego faced a traffic nightmare Monday morning after two water mains burst Sunday, leaving a section of northbound Interstate 5 under water.

Starting around 11 p.m., all traffic on north I-5 was being diverted to north state Route 163. Crews were working to pump water out of the flooded lanes but no estimates were given as to when the freeway lanes would be driveable.

California Spent Decades Trying to Keep Central Valley Floods at Bay. Now It Looks to Welcome Them Back

Land and waterway managers labored hard over the course of a century to control California’s unruly rivers by building dams and levees to slow and contain their water. Now, farmers, environmentalists and agencies are undoing some of that work as part of an accelerating campaign to restore the state’s major floodplains.

How Improved Atmospheric River Forecasting Can Help Keep Water Flowing in California

/in , , /by /ABC10by Monica Woods

Atmospheric rivers can bring dangerous flooding, but, without them, California can head into drought. Improving forecasts for these huge storms is a focus for the Center for Western Weather and Water Extremes to keep water flowing in the state.

Marty Ralph remembers living in Los Angeles in the 1980s when a huge rainstorm dropped nearly half the rainfall for the whole year in 12 hours. It was at that moment he realized he wanted to study these kind of storms

Level 5 Atmospheric River to Unleash Flooding Across Drought-Stricken California

/in , , /by /CNN Weatherby Pedram Javaheri

After nearly a year without rain, a series of potent Pacific storms are directed at Northern California this week, potentially bringing as much as a foot of rainfall and up to three feet of snow in the Sierra Nevada.

Supercharged by a classic atmospheric river pattern, the storms could lead to flash floods and dangerous debris flows in a wide swath of the region already devastated by recent wildfires.
