...FIRE WEATHER WATCH IN EFFECT FROM SATURDAY MORNING THROUGH
SATURDAY EVENING FOR FOR WIND AND LOW RELATIVE HUMIDITY FOR
FIRE WEATHER ZONES WA691, WA692, WA693, OR691, OR692, OR693,
OR694, OR695, OR696, OR697, OR698, OR699, AND OR700...
.DISCUSSION...A weak system is passing over the region, providing
a slight increase in cloud cover and winds. An even weaker system
is expected on Friday ahead of a dry cold front that passes on
Saturday. Critical fire weather concerns arise Saturday due to the
front`s passing, bringing windy conditions to much of the area as
dry conditions persist, especially across our southern zones.
***Winds are 20 foot 10 minute averages ***
***CWR: Chance of wetting rain 0.10 or greater ***
***Ventilation Index is derived from transport wind
multiplied by the mixing height in 100`s of ft.
Categories are a generalized indicator and users
are encourage to develop criteria that are
suitable and representative of dispersion
conditions in their local area of interest.
Categories: low (< 200), moderate (200-500),
high (500-700), and very high (> 700).
-Note: Max transport winds may not occur
at the same time as max mixing height. ***
