Raws Information

Each RAWS summary contains three main columns. Each column represents
up to
a 12 hour period. If the current time is between 1800 UTC and 0600 UTC,
then you will see "Since 1800 UTC", "0600 UTC to 1800 UTC", and "1800 UTC
to
0600 UTC" column headings. If the current time is between 0600 UTC and
1800
UTC, then you will see a "Since 0600 UTC", "1800 UTC to 0600 UTC", and
"0600
UTC to 1800 UTC" column headings. Weather element labels have the
following meaning:

Tx Maximum Temperature
Tn Minimum Temperature
RHx Maximum Relative Humidity
RHn Minimum Relative Humidity
Dir Wind Direction at time of maximum speed
Spd Maximum Wind Speed
GD Wind Direction at time of maximum gust speed
GS Maximum Gust Speed
Rain Rainfall in inches

Note that the vast majority of RAWS rain gages are not heated. Therefore,
water equivalent from frozen precipitation can usually not be measured.
Since frozen precipitation accumulates on the gage, subsequent above
freezing temperatures will cause the precipitation to melt into the gage.
This can give the false impression that precipitation is occurring even when
it is not.

Due to wildfire and other land management concerns, many RAWS in complex
terrain are strategically located on south to west facing slopes. These
slopes receive more solar radiation than other aspects and generally
represent the warmest and driest conditions for a given area. A very small
percentage of RAWS may contain erroneous observations due to
mis-calibration
of weather sensors, but the majority of observations are of high quality.
Updated RAWS summaries are typically posted at 30 minutes past the hour.
Always check the run time of the summary to make sure that it is less than
one hour old.

Printing Instructions:

Due to the width of text in the RAWS Summary, text wrapping will occur if
you print directly from your browser. To solve this problem:

1. Copy the summary and paste it into a word processor.
2. Change the font size to 8 point New Courier.
3. Change the page or print setup to landscape.
4. Print.
