The "rainfall year" in the Pacific Northwest runs from Oct 1st
to Sept 30. Summers in the northwest are typically very dry, with
little rain falling between late June and early October. Moisture
in the form of mountain snow pack and reservoire cache accumulated in the
fall contribute significantly to the total available water for the following
summer. Fire season severity, crop irrigation and mumicipal water supplies
are calculated based on seasonal rains that fall the entire autumn through
spring. The total rainfall reported above is based on a September
This page is not an operationally

The Rock Creek Neighborhood weather station moved to a new location
within the Rock Creek neighborhood in May of 2003. Old data should
remain essentially relavent as the move was only a few hundred feet down
the street. The new locataion has a number of advantages.
The anamometer and wind vane are now fully 30 feet (10 meters) off the
ground and some distance from the nearest trees in any direction. The
thermometer is in a more protected location that should be protected from
direct sun or radiation heating from the ground or fence year round. See
the installation here.
Squirrels pretty much
destroyed the original thermometer/hygrometer system. They chewed the
case of the solar system and compromised its watertight integrity. Also,
the line connecting the sensor with the solar powered transmitter was severed.
Repairs were not watertight, causing significant corrosion. The
solar powered unit was replaced with a less expensive battery powered unit.
Unfortunately, the range is significantly less, requiring the sensor
to be relocated. Additionally, this device reports on channel 1 rather
than the base outdoor channel. The software has a switch ot use channel
1 for temperature, but it ignores the humidity, thus not calculating a dew
point. I'm working with the vendor on these issues.
