...HOT, DRY, WINDY, AND POTENTIALLY UNSTABLE CONDITIONS EXPECTED FOR SOUTHEASTERN OREGON ON SATURDAY... .A robust low pressure system centered off the coast of the Pacific Northwest will orient the winds aloft more southerly, pushing in a hot and dry airmass into southern Oregon. Relative humidities will drop significantly as a result on Saturday. This, combined with the low pressure system amplifying the wind speeds, will potentially lead to critical fire weather conditions across much of southeastern Oregon. Unstable conditions are possible as well, with values of 5 and locally 6 possible during the day Saturday. The National Weather Service in Pendleton has issued a Fire Weather Watch for wind and low relative humidity, which is in effect from Saturday afternoon through Saturday evening. * AFFECTED AREA...Fire Weather Zone 642 Southern Blue and Strawberry Mountains. * WINDS...South 15 to 20 mph with gusts up to 30 mph. * RELATIVE HUMIDITY...As low as 8 percent. * IMPACTS...Gusty winds with dry conditions may lead to rapid fire spread. Unstable conditions may promote extreme fire behavior as well.

The National Weather Service in Medford has cancelled the Red Flag Warning. Thunderstorms have not developed today and none are expected through the remainder of the night. A Fire Weather Watch continues in effect from Saturday afternoon through Saturday evening. * IMPACTS...Fire could spread rapidly. * AFFECTED AREA...Southeast Lake county including the Warner Peak Fire, Adel and Hart Mountain Refuge. * WINDS AND HUMIDITY...South winds 20 to 30 mph with gusts up to 45 mph combined with humidity 10 to 15 percent. * DETAILED URL...View the hazard area in detail at https://www.wrh.noaa.gov/map/?wfo=mfr
