Issue:

A data pipeline issue has been identified that has caused precipitation data at some South Dakota Mesonet stations to be underreported when one minute out of every five was not included in totals. The excluded minute of data was collected and stored but not displayed. See the table below listing the dates and stations impacted.

The South Dakota Mesonet team works to bring our stakeholders the best possible data. We apologize for any inconvenience this issue may have caused and appreciate your patience as we work to remedy the issue. Thank you to those that helped bring this to our attention and narrow down the problem.

Data dated May 22, 2024 onward are not impacted by this issue.
