Statistics are based on records dating back to September of 1896. There are some gaps in the data with a few years through the record missing for several months. This is mostly due to the fact that the data for those months weren't actually recorded.
Remember, this data is based on the number of times that measurable precipitation has fallen on a
particular day, not the total amount.
