10/14/2017 7:00 AM 0.97 M M M M At about 6:10-6:15? I woke up to the alarm, looked at clock and the sky opened up. Fell back asleep. Rain just stopped after a very heavy downpour. Got up, and checked the gauge at 07:00. It was full, and the rain had ceased for a few minutes. So I hurried along and took our 6 mo. puppy out for his walk, and we stayed dry!! It started to rain again just as we headed back into the house.
