...RED FLAG WARNING IN EFFECT UNTIL 5 PM PDT MONDAY DUE TO GUSTY
WINDS AND LOW RELATIVE HUMIDITY FOR PORTIONS OF THE SACRAMENTO
VALLEY AND NORTHERN FOOTHILLS...
Breezy north to east winds and dry conditions today, with winds
strengthening through the Valley tonight into Monday. Gusts from
25 to 35 mph at times. These gusty winds combined with low
humidities will yield critical fire weather conditions across the
Sacramento Valley and northern foothills. A Red Flag Warning
remains in effect through 5pm PDT Monday for portions of the
Sacramento Valley and northern foothills. Locations outside of the
warned area, such as along the Sierra crest, will see periodically
elevated fire weather conditions as well, but should remain below
critical conditions. Expect below-normal temperatures today,
followed by near-normal conditions the remainder of next week.
