I was out driving a couple of hours ago and the rain wasn't that heavy, it was just steady, must have been heavier elsewhere.
You got lucky.
I took the day off today for a specialists appt this morning. Got home just before it hit. We got about 20-30 minutes of hard rain. Like those downpours that only last a couple of minutes ... but this one went on and on before letting up. The house was fine, but the backyard and our street, there was no nowhere for the water to go. My paved patio area had about 25 mil standing water, and big puddles formed everywhere else. It just couldn't drain away fast enough. The street was awash with puddles too along the kerbs.
