It didn't seem like much of a rainstorm, since it happened slowly enough that a lot of the rain could soak in, and it was at night without a lot of rumbling.

We both heard it raining, but it didn't seem like it ever rained really hard. But when we got up in the morning, the rain gauge on the deck said 3.6". The ground was dry but not parched, so a lot of the water soaked in. There was some standing water in the storm drain easement for the sub, but not nearly as much as we'd expect from that much rain.
