  By now, the upcoming weather next week is second to Haiti
for the news.   We are going into permit suspension but at this
time we do not know exactly as we are watching the weather so
as not to pull the trigger too early.  We are also working in
concert with County Roads and CALTRANS so the suspensions and
road closures are more inline with each other.
  The suspensions only apply to permits on Forest Service
land and not to private property.  That will be handled by the
Sheriffs.  For private property owners on the list, this is
information only.
  The County will be closing their gates and the only
permittee we have behind the gate is Clear Creek Education
Center.  But there are several private property owners that
will be behind the lock gates.
  The suspension, based on current weather forecasts, will
either come Sunday or Monday.  So if you are going out of town
for the holiday weekend, be prepared that you may come back
and not be able to get back to your permit.

  [The impact of this e-mail on Mt. Wilson users is unclear.
  According to Graham Breakwell of the Forest Service, the issue
  of road closures has become complex.  Mike McIntyre is
  reportedly ill but has come into the office today, Friday,
  specifically to address the closure issue.  CGC will continue
  to monitor the situation.   -Ed.]
  Re your reference in CGC #987 to the National Weather
  Service weather prediction page, I prefer
  (that's the prediction map for 12Z Monday, or 5 AM PST).
  You can scroll through the forecasts (note of course the
increasing unreliability more than 96 hours out).  Then, if
you're curious, check out the 300 mB chart, which shows the
"steering currents" in the upper atmosphere (300 mB is roughly
30000 feet).
  Note that the scale (in color) only goes to 200 knots,
and that this is reached even over land area in socal by midweek.
Believe me when I report that this is *very* unusual in duration,
location and intensity.
  If this pattern were to persist for a month (no chance!),
it would both turn the entire southwest to mud and relieve the
drought.  Imagine the LA river bursting its concrete banks....
