Los Angeles Fire Chief Kristin Crowley said on Tuesday that crews had responded to 307 mudslides and that five buildings had been deemed uninhabitable since an atmospheric river-fuelled storm moved into the region over the weekend.

Despite the record-setting rain that has drenched the city and caused widespread flooding, there have been no storm-related deaths reported in Los Angeles, Mayor Karen Bass said at a news conference.

The rain began to ease on Tuesday after bombarding Los Angeles with nearly half of its seasonal rainfall in just two days.

Although the rain was tapering off, forecasters warned of the ongoing threat of potentially deadly landslides.
