Note: In June 2013, the Climate Prediction Center made modifications to the U.S. Drought Outlooks. One of the major changes
involved the replacement of the updated Seasonal Drought Outlook (SDO) with a new Monthly Drought Outlook (MDO).
This change is reflected in the "Verification" column of the SDO archive table, starting with the July-September 2013 outlook
(released on June 20, 2013), as there is now only one SDO verification link. Prior to this time, an SDO verification was made for the
initial as well as the updated Seasonal Drought Outlook. Verifications for the MDO are available
on the Monthly Drought Outlook archive web page.
