...FIRE WEATHER WATCH IN EFFECT THROUGH MONDAY EVENING FOR FIRE
WEATHER ZONES WA690 AND WA691 FOR WIND AND LOW RELATIVE
HUMIDITY...
.DISCUSSION...Hot and dry conditions continue for the next several
days with critical minimum humidity values for the low and mid
elevations with moderate RHs in the higher terrain. Expect
moderate recoveries in the mid slopes and low elevations.
Increasing winds through the Cascade gaps and through the lower
Columbia Gorge, with gusts to 30 mph, on Monday will produce
critical fire weather conditions in these areas.
***Winds are 20 foot 10 minute averages***
***CWR-chance of wetting rain 0.10 or greater***
***Ventilation Index is derived from the
transport wind multiplied by the mixing
height in 100`s of feet. Index 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.***
Note: Max transport winds may not occur
at the same time as max mixing height.
