via campmate and hydrologist, Carbon Buildup:
Gerlach, NV is supposed to get an inch of rain over the next four days,
on top of what they've already had recently. That is actually enough
to make parts of the Black Rock Desert into Black Rock Lake, literally. I
wouldn't expect there to be standing water by the end of August, but
these late rains do wonders for 'cementing' the alkali silts of the
playa. We will have to work extra hard to have dust storms this
year...
Same thing is happening in other normally dry areas. On Tuesday night
Bend, Oregon got six inches of hail. And another half inch of rain
fell there last night, causing localized flooding. Lakeview, Oregon
and Alturas, California are getting dumped on too. This is not a good
time to head out into those areas for any recreation, and certainly
not a good time for early playa touring or pre-Burning Man projects.
This storm is predicted to last through Monday. However, if you are
careful and have a strong desire to see deserts flooding, then you
should make the effort. It really is an amazing thing to see. [emphasis
