diseased lilac

When we moved in four years ago, we inherited 3 mature lilacs which bloomed profusely until last year. Some of the leaves puckered and then blackened and we got many fewer blooms. Spring had been late and unusually wet--even for the Northwest. I cut every diseased branch back well below what looked diseased. This year, everything was looking fine and then it happened again--as did the late, wet spring.
What is wrong with them and what can I do about it?
Pictures are below. Thank you for any help you can offer!

RE: diseased lilac

Lilac blight. A common disease of lilacs, made worse during especially wet springs.

Treatment is essentially as you're doing. -- during dry weather, prune well below the damage

Thank you jean001a. Now waiting for the dry weather will be a WAIT. Dry tomorrow, but rain is coming again for us.
