In Los Angeles, Mayor Eric Garcetti has instituted a shutdown on a city of nearly 4 million people and threatened uncooperative business owners with power shutoffs and arrest.

By midday Monday, California had more than 6,300 cases and 132 deaths of reported cases, according to a running list by Johns Hopkins University.

Los Angeles Mayor Garcetti has assigned teams of city workers to ensure non-essential local businesses are complying with shut down orders.

He is empowered to shut off their water and power if necessary, and the California Democrat has authorized the police to arrest those who continue to resist.

Garcetti said there have been no shutoffs or arrests so far and predicts that '99 out of 100 will comply.'

California is enlisting retired doctors and medical and nursing students to help treat an anticipated surge of coronavirus patients, the governor announced Monday.

The community reportedly tried to justify their gathering by saying 'it's a kid's party'

At some moments it looked like a riot was going to break out as the group refused to follow guidelines

The California Health Corps effort comes as the nation's most populous state anticipates hospitals becoming overwhelmed with patients and while it is preparing stadiums and convention centers to handle a crush of cases.

The announcement came as San Francisco and six surrounding counties said they would extend stay-at-home orders until May 1.

Over the weekend, more people appeared to heed the message to stay home after beaches and many parks were closed by state and local officials following a swarm of visitors during the first weekend of the state's stay-at-home order.

Still, people continued to crowd some of the open parks. On Sunday, the state expanded closures amid concerns people were not keeping a proper distance from one another. Parking lots at all state parks were closed, and the most popular places were closed to all activities.

A surfer in Manhattan Beach south of Los Angeles was issued a citation that could carry at $1,000 fine for violating orders to stay off the beach.

To help prepare for a wave of patients, National Guard troops set up beds in the sprawling Los Angeles Convention Center, converting it from a site that normally hosts meetings, trade shows and exhibitions into a field hospital.
