See the Historical NWAC Climatological Snowdepth Data & Plots page
for custom plots and data back to the 1916-17 season.
See the main Cascade Snowfall and Snowdepth page, plus
Snow Season Reports: 2005-2006, 2004-2005,
2003-2004, 2002-2003

This page concatenates and prints telemetry data for the last 10 days for any
Northwest Weather and Avalanche Center (NWAC) telemetry site. The current data
is printed first with full headers, followed by the archived data for each of the past 10 days ending at 4AM (headers printed only
for the first day), with the current data also appended to the end. Alternately, the data can be shown in reverse chronological
order, which seems to be preferred by most people.
As of November 2009, a version of this 10-day concatenation script has been added to the telemetry display on the NWAC website.
Unfortunately, archived telemetry data older than 10 days is not yet available online from NWAC as of fall 2013.
I've also written a more flexible viewer script for NWAC telemetry which uses this code, and has numerous options for concatenating
all sites, or displaying 2 sites side-by-side for comparison: CascadeSnowNWAC-Data.php

New NWAC website of October 2009 broke this page, since all URLs there were changed.
