* = Data is missing or invalid.
Units = inches for current and average values; percentages for percent of average values.

The MONTH-TO-DATE PRECIPITATION Departure from Average represents the difference between the current month-to-date precipitation (precipitation accumulated beginning on the 1st day of the current month through the current day) and the average month-to-date precipitation for the same time period presented in both inches and percentages.

The YEAR-TO-DATE PRECIPITATION Departure from Average represents the difference between the current year-to-date precipitation (precipitation accumulated since the beginning of the water year, October 1st, through the current day) and the average year-to-date precipitation for the same time period presented in both inches and percentages.

Contact your state water supply staff for assistance.

Reference period for average conditions is 1971-2000.
