Drought Misery Index

With the ongoing drought, I came up with the Drought Misery Index (DMI), which is similar to the Misery Index for the economy. Here is the formula for Drought Misery Index.

Palmer Drought Severity Index (PDSI) + Precipitation (PCP) = Drought Misery Index

-8.00 + 1 = -7.00

The more negative the DMI, the worse the drought is. Here is the current DMI, based on September outcome.

-4.78 (PDSI) + 2.00 (PCP)
Lowest: -6.01 August 1934
Highest: +9.91 May 1983

-3.78 (PDSI) + 1.29 (PCP)
Lowest: -7.22 September 1956
Highest: +15.51 October 1919

Upper Texas Coast
-2.05 (PDSI) + 2.43 (PCP)
Lowest: -4.64 July 1925
Highest: +20.98 October 1949

All data is from the Division Data and it can change as more data is put in and averaged out.
