STATUS: Active, Seasonal

ABOUT THIS DATA:

The biweekly snow depth (cm) and snow water equivalent (mm) for the Pierces Corners region (SNOW-MNR-3306). Field monitoring conducted by the RVCA. Statistics have been generated by the RVCA from the period between 1977-2019 (42 years). These statistics include the biweekly median (50th percentile), interquartile range (data range between the daily 25th and 75th percentiles) and the maximum snow water volume measured over the period of record. The median and interquartile range represent the typical normal snow water volume observed at this time of year over the historic record.
