Manual deletions for stations MZL, LAP, MEX, and CUR were almost entirely
due to warm temperatures and/or high heights.  With respect to equipment
failure reports, SXM reported ground equipment failures at least one time
on most days starting on the 14th of October.  In addition, AKN reported 
ground equipment failures from the 18th through the 20th, and MZL reported
a few ground equipment failures throughout the month.  From the 22nd through
the 31st, GYM reported a combination of ground equipment and flight equipment
failures.  SYA also reported numerous flight equipment failures since the
24th.  In the first 3 weeks of the month, SYA reported numerous weak signals.
Finally, GDL submitted a variety of equipment reports throughout October,
including preventative maintenance on the 13th-14th and 16th-18th.

* The total differs from the sum of the itemized citations
  because of multiple citations in the same raob(s).


Citation Codes Key:
DEL  All or part of the raob was flagged for deletion.
BAS  A baseline hgt/station press error was corrected or purged.
COR  At least one correction other than baseline was made.
XRP  Station sent no report at all when one was required.
EFL  Equipment failure (codes 10142, 10144, 10158, etc.)
SHO  Raob flight was short; ie, to less than 400 mb.
