...RED FLAG WARNING IN EFFECT UNTIL 11 PM PDT THIS EVENING FOR FOR
WINDS AND LOW RELATIVE HUMIDITY FOR LOWER COLUMBIA BASIN OF OR &
WA, EASTERN COLUMBIA RIVER GORGE, WARM SPRINGS RESERVATION,
KITTITAS VALLEY...
.DISCUSSION...Breezy to windy conditions are expected through this
evening, with winds in the 25 to 30 mph range and possibly as
high as 40 mph in some areas. These winds, together with low
relative humidities are continuing critical fire weather
conditions across the area. On Sunday, winds are expected to
decrease to 20 to 25 mph, with a decrease in temperatures. The
decrease in winds and temperatures will also increase RH and fire
weather concerns will become elevated into early next week.
***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. ***
