The two easiest for me to see and understand are the "CPC soil moisture models" and the "USGS weekly streamflow" both of which are percentile rankings.

Right now our area is in the 1-5 percentile of soil moisture and 1% of normal streamflow. Those are pretty low measurements by any standard.


It may be a little bit of scientific mumbo jumbo..................................but it's decent mumbo jumbo for what that's worth.


Gotcha - Bad chartsmanship then - you define it on the chart and don't make people go elsewhere that info. It would be an even better chart if they didn't call it a drought chart and instead covered their scale. Many of those white areas (including mine) are above normal rain this year.
