Seattle just cancelled K-12 schools for 6 weeks. I don't have any idea if they are going to try to make up all that time over the summer.
Portland schools are still on, but my kid's middle school track practices are all cancelled. Doesn't make a lot of sense - gather the kids together indoors, but cancel the time they are all running outside? Anyway, I think it goes along with cancelling all sports and extra gatherings.
