Don't hava rain gauge (kind of a useless item for SoCal!!!) but I would guess several inches. I know it filled up the dog dish so the stray pusses now have fresh water. I should measure the Mosquito breeding pond (defunct pool) to see if it went up. looks cloudy today, they said somehting about more showers tonight. It better not rain before midnight though!! tonight is our company Christmas party and I'm gonna have my TUX on that I don't want to have to dry clean!!
