Mapping 30 Years of Weather


EcoWest has released two interactive maps which allow you to explore 15 years of drought data and 34 years of precipitation data.

The Tracking US Drought Severity map visualizes the weekly drought designations from the U.S. Drought Monitor from the beginning of the 20th Century. Select a date from the timeline beneath the map and you can view a heat-map of the drought conditions during that week.

The timeline includes a graph showing the proportion of drought over time for the location selected on the map.

Rain and Snow in the U.S. Since 1981 is a map showing the total monthly rain and snowfall totals across the country. Again you can use the timeline beneath the map to choose a date and view a heat-map of precipitation levels for the selected month. This time the timeline includes a graph which show the total rainfall for each month since 1981.
