Expert Response

I believe that this is a disease called bacterial canker. Cherry trees, especially those grown in higher rainfall regions are very susceptible to this disease. Here is more information on the disease: https://pnwhandbooks.org/plantdisease/host-disease/cherry-prunus-spp-bacterial-canker.
