The Washington Post scrapes data for its coronavirus counter and puts California at 6090 today from a record 11,529 yesterday. That's a rise of 2.2% but the past three days may have been skewed by the long weekend.

Update: This is now confirmed. There are also numbers on hospitalizations, which rose 3.4% to a record 5989
