King tides and heavy rain caused significant flooding in Marin County, California, inundating roads and homes, with residents experiencing unprecedented water levels and sharing community efforts to manage the flooding.
Marin County health officials report the spread of a new COVID-19 omicron variant, JN.1, which is estimated to account for 20% of cases in the county and up to 50% of U.S. cases. The variant is more transmissible but not linked to more severe illness. Despite the availability of a vaccine effective against JN.1, only half of Marin's most vulnerable population has been vaccinated. As schools reopen after the holiday break, officials emphasize adherence to COVID-19 protocols, including testing and mask-wearing for symptomatic individuals.
