Tilting of the (drought) scale

Let me tell ya:

It's dry out there ...

This chart provides a summary of drought conditions across the Everglades and Big Cypress using the popcorn scale.  The red arrows indicates current levels, the dark gray arrows a month ago, and the light gray arrows a year ago today.  The dotted line shows the long-time normal level for early March.

But there's still a lot of time for it to get a lot drier.

Big Cypress National Preserve is in what I call "tortilla chips surrounded by rapidly receding bowl of salsa" mode.  That means that the deep areas in the middle of the domes, strands and marshes are still flooded, but increasingly its dry everywhere else.  Normally this time of year we'd have about a foot of water in the center of the domes.  This year it's closer to a few inches.  A year ago today it was almost 2 feet (i.e. remember the Super El NiƱo?).


In comparison, the Everglades are holding more water (and deeper) than the adjacent and higher perched swamp.

As shown above, most areas of the glades are about a foot deep.
