The air around the Puget Sound region had a different smell Thursday as smoke from wildland fires in Central and Eastern Washington moved westward.
The NWS has issued a Red Flag Warning for most of Western Washington until 8 p.m. Thursday. The Red Flag Warning means that critical fire weather conditions are either occurring now or will shortly. A combination of strong winds (north to northeast 8 to 14 miles per hour with gusts up to 20), low relative humidity (15-20 percent) and warm temperatures (80-85 degrees) will create explosive fire growth potential.
From the website, the Red Flag Warning is due to:
A THERMAL TROUGH OF LOW PRESSURE OVER WESTERN WASHINGTON WILL SHIFT EAST OVER THE CASCADES THIS EVENING THEN INTO EASTERN WASHINGTON FRIDAY. THIS PATTERN WILL RESULT IN LOCALLY BREEZY EAST WINDS ACROSS THE WEST SLOPES OF THE CASCADES INTO THE IMMEDIATE FOOTHILL AREAS AND THE RIDGES OF THE EASTERN OLYMPICS. THE WIND WILL THEN EASE TODAY AS THE THERMAL TROUGH MOVES OVERHEAD. HOWEVER THIS WILL BRING UNSTABLE HIGH HAINES CONDITIONS TO MOST OF WESTERN WASHINGTON WITH A SIGNIFICANT PORTION OF THE AREA HAVING MINIMUM RH VALUES BELOW 25 PERCENT THIS AFTERNOON. THE WESTERN OLYMPICS AND THE COASTAL AREAS HAVE BEEN LEFT OUT OF THE WARNING DUE TO THE AMOUNT OF RAIN RECEIVED SUNDAY NIGHT.
The NWS asks that you avoid tossing any burning materials out of vehicles, avoid any outdoor burning, tie up any loose chains involved with towing operations on roadways to avoid sparks, avoid driving over any grassy areas where hot undersides of vehicles can spark the dry vegetation, and obviously--no fireworks.
