History of flash droughts

You never have a flash drought.

Dry spells are usually months in the making.

This historical chart highlights periods and levels of drought in Big Cypress National Preserve from 1992 to present.  The chart is also annotated with major wildfires.  Can you see how major wildfires generally coincide with the deepest descents into drought?

But wildfires can flash when the swamp descends into drought.

This spring that has happened again.

Time to add the Mud Lake Complex to the historical chart.
