-M = Missing data
 * = Data may not provide a valid measure of conditions.
 
     If the Basin wide percent of average value is flagged as potentially
     invalid, care should be taken to evaluate if the value is representative
     of conditions in the basin.

The SNOW WATER EQUIVALENT Percent of Average represents the snow water
equivalent found at selected SNOTEL sites in or near the basin compared to
the average value for those sites on this day.

The TOTAL PRECIPITATION Percent of Average represents the total precipitation
(beginning October 1st) found at selected SNOTEL sites in or near the basin
compared to the average value for those sites on this day.
