The governor announced the limit on crowds and increased testing capacity in written form tonight and will explain her decision at a press conference Thursday morning.

Meanwhile, a similar decree was ordered in Washington. Seattle Weekly reports:

All events with more than 250 people in King County will be prohibited following orders from state and local officials on March 11 in an attempt to slow the spread of COVID-19.

Gov. Jay Inslee announced at a press conference Wednesday morning that all events larger than 250 attendees will be banned in King, Snohomish and Pierce counties through the end of March. He said it will likely be extended beyond that.

It applies to all social gatherings, including church events, concerts and sporting events.

In addition, events smaller than 250 attendees will also be prohibited in King County unless organizers can meet certain criteria for social distancing and COVID-19 screening. County Executive Dow Constantine said he had directed the county’s Public Health Officer Jeff Duchin to sign the measure authorizing the restrictions. The orders went into effect on March 11 and there is no specific end date.
