Big though!Strangely, our weather station reports both daily values and monthly accumulation - and they do not agree. October total shows 20.21" which is amazing, but the daily totals sum to 18.9 inches. Either number is over 3x the 30-year average of 5.5", so it was a very wet month! Octobers in this region are often beautiful for a week or two, but not this year; weekends in particular were stormy, and intervals between storms few.
I have seen previous months were off a bit but this month was so damp that the discrepancy was notable.
