Historical Precipitation

This interactive graphing tool shows precipitation trends, of which very dry periods are a drought indicator. It can also be used to help estimate the probability of future precipitation and hence drought events.   1. On the left side column (moving from top to bottom) choose Utah → Climate Division of Interest → Season of Interest → Precipitation. 2. Hovering the cursor over a point will display the year and total rainfall for the selected season. 3. For more information on how to interpret the chart, click on Chart Info.
