Seawater surges into low-lying communities from San Diego to San Francisco Bay Area, submerging streets, homes and businesses

Historic high tides have caused chaos up and down the California coast this week, as parts of the state were inundated by record-breaking water levels. Seawater surged into low-lying communities from San Diego to the San Francisco Bay Area, submerging streets, flooding homes and businesses, and jamming important transportation corridors and train routes.

Kayakers and paddleboarders could be seen gliding through typically busy thoroughfares in Marin county, north of San Francisco, on Monday and Tuesday. Several drivers had to be rescued from floating cars in the area, while cyclists who had attempted to cross the temporary lagoon that had formed quickly found themselves waist-deep. Further south, in cities such as Newport Beach, water pounded the emergency infrastructure set up to keep out the swelling sea, which seeped through berms, seawalls and sandbag blockades along the shoreline.

President has taken an axe to National Oceanic and Atmospheric Administration, stalling climate research on and response to extreme weather events

Sweeping cuts to the premier US climate agency under Donald Trump have severely hampered the country’s capacity to forecast, research and respond to extreme weather events, former government officials and scientists have warned, as the US faces a cascade of hazards fueled by a potentially historic El Niño this winter.

From the start of his second term, the president has taken aim at the National Oceanic and Atmospheric Administration (Noaa), slashing staff levels, canceling contracts and grants, and shutting down databases and research laboratories. The agency that has long been considered a global crown jewel in climate science and forecasting has lost roughly 20% of its staff since January 2025.
