Hmph. Wind died down, but my guess is that it didn't die down quite soon enough. Because in contrast to last night, rain is pouring, not dripping, out of my ceiling already. Feh. Still better than the 8gal/hr mess, and I don't see any in the doorway in the wall that channelled it to the server room before, so the effort may not have been a complete waste, but still discouraging.
Hope it doesn't keep raining long enough to require dumping a bucket, 'cause raising my arms hurts rather a lot right now.
Rehearsal iffy. Will try ...
