Blowing out the little holes appear to have been the solution. We have not had the problem since. However, I do plan to clear the holes annually with an air compressor attachment.
Couple of additional comments. Our 37TB is now in covered storage when not in use and I added gutters to assist with the water flow from the roof.
Hope this helps and feel free to reach out if I can add further clarification.
