Mandy Moore is grieving the loss of her neighborhood and her home, which was ravaged by the still-active Eaton Fire burning in Los Angeles County.

The former "This Is Us" star returned to find the main part of her Altadena, California, home "miraculously" still standing, though not livable, she said in an Instagram post.

This Is Us' star Mandy Moore has revealed her heartbreak after her Altadena neighbourhood has been burned down in the LA fires.

The intense water demand resulting from the Palisades Fire has led Los Angeles to issue a boil water warning. The only zipcode impacted is 90272, and nearby North of Vicente. City officials have warned that the fires are leading to ash integrating into the water system and that further warnings could be issued .

The Sunset and Kenneth fires follow other blazes in the L.A. area, including the Palisades and Eaton fires, that have displaced tens of thousands.

The death toll from the multiple fires raging across Los Angeles County rose to 10 on Thursday night, as the largest of the five blazes—the Palisades Fire—grew to cover nearly 20,000 acres as strong winds meant the “Red Flag” fire weather conditions will remain in effect until Friday evening.
