There are a couple of possible explanations. The first, and most likely, is that it is actually physical damage from rain or rain driven dust, particularly if the rain was quite hard for a time. If this is the cause, it should continue to dry out, but not spread any further, and will ultimately have a pretty well defined edge on the drier spots.
There is also a fairly mysterious ailment that agaves can develop that looks similar to this. This ailment, whom no one has successfully identified yet to my knowledge, would begin at the base of the leaf, spread to about half way up the leaf, pale the leaf significantly first then leave that portion very dry and corky. The edges are ragged and uneven. This ailment does not appear to affect the general health of the plant
in most cases, but it severely mars its appearance.

> I have noticed white spots on my Agave ocahui.  In some areas on the leaves there is some 'dimpling' and then there are larger white 'dead' areas. I looked at other Agave ocahui plants in my neighborhood and they have the same symptoms.  My Agave vilmoriniana does not appear to be affected although my Agave parryi is.  I noticed these symptoms after all of the rain we received this week.  Any input would be appreciated.
