An upper level low will move up from the south along the California coast late this afternoon, and will tap into increasing mid-level moisture. Meanwhile, elevated instability will increase and this combined with a moderate to strong trigger could result in isolated to scattered thunderstorms this evening into Sunday morning, and again Sunday afternoon and evening. Given how dry fuels are, along with continued hot temperatures, lightning efficiency will be high to very high for fire starts. The National Weather Service in Medford has replaced the Fire Weather Watch with a Red Flag Warning, which is in effect from 5 PM this afternoon to 8 AM PDT Sunday. * IMPACTS...Given the prolonged stretch of very hot and very dry conditions, lightning efficiency will be high to very high for fire starts. Additionally, gusty outflow winds will allow for new and existing fires to grow rapidly out of control. * AFFECTED AREA...All of Fire Zones 615, 616, 617, 618, 619, 620, 622, and 623. * THUNDERSTORMS...Isolated to scattered thunderstorms are expected late tonight into early Sunday morning. Lightning strikes outside of precipitation cores are possible and cause for concern. * OUTFLOW WINDS...Gusts up to 40 mph.

The Oregon Department of Environmental Quality issued an air quality advisory for Klamath and northern Lake counties due to numerous wildfires burning in the region. DEQ also expects other areas of the state may see intermittent smoke from ongoing large wildfires, including eastern Douglas and northeast Jackson counties. The wildfire smoke combined with forecast conditions will cause air quality levels to fluctuate and could be at unhealthy levels. Smoke levels can change rapidly depending on the weather. Smoke can irritate the eyes and lungs and worsen some medical conditions. People most at risk include infants and young children, people with heart or lung disease, older adults and pregnant people. People can take the following precautions to protect their health: - Follow local burn restrictions to prevent deteriorating air quality. - Avoid strenuous outdoor activity during periods of poor air quality. - People with heart or lung problems and young children are especially vulnerable. These people should stay indoors while smoke levels are high. - Use certified High Efficiency Particulate Air (HEPA) filters in indoor heating, ventilation, cooling and air purification systems. - Avoid using wood-burning stoves and other sources of indoor smoke if possible. DEQs color-coded Air Quality Index provides current air quality conditions and ranks air quality as follows: Green is good. Yellow is moderate. Orange is unhealthy for sensitive groups such as children, the elderly, pregnant women and those with respiratory conditions. Red is unhealthy for everyone. Purple is very unhealthy for all groups. Maroon is hazardous.

An upper level low will move up from the south along the California coast late this afternoon, and will tap into increasing mid-level moisture. Meanwhile, elevated instability will increase and this combined with a moderate to strong trigger could result in isolated to scattered thunderstorms late this evening into Sunday morning, and again Sunday afternoon and evening. Given how dry fuels are, along with continued hot temperatures, lightning efficiency will be high to very high for fire starts. * IMPACTS...Given the prolonged stretch of very hot and very dry conditions, lightning efficiency will be high to very high for fire starts. Additionally, gusty outflow winds will allow for new and existing fires to grow rapidly out of control. * AFFECTED AREA...All of Fire Zones 615, 616, 617, 618, 619, 620, 622, and 623. * THUNDERSTORMS...Isolated to scattered thunderstorms are possible late tonight into early Sunday morning. Lightning strikes outside of precipitation cores are possible and cause for concern. * OUTFLOW WINDS...Gusts up to 40 mph. These outflow winds can travel up to 50 miles away from the thunderstorm that caused it. * DETAILED URL...View the hazard area in detail at https://www.wrh.noaa.gov/map/?wfo=mfr Fire Weather Watch 2024-07-20T03:12:00-07:00 2024-07-20T03:12:00-07:00 2024-07-20T17:00:00-07:00 2024-07-20T16:00:00-07:00 Actual Update Met Future Severe Possible South Central Oregon Coast; Umpqua Basin; Umpqua National Forest; Southern Oregon Coast; Western Siskiyou National Forest; Western Rogue Basin including the Illinois Valley; Eastern Rogue Valley; Southern Oregon Cascades SAME 041011 SAME 041015 SAME 041019 SAME 041029 SAME 041035 SAME 041039 SAME 041033 SAME 006015 UGC ORZ615 UGC ORZ616 UGC ORZ617 UGC ORZ618 UGC ORZ619 UGC ORZ620 UGC ORZ622 UGC ORZ623 AWIPSidentifier RFWMFR WMOidentifier WWUS86 KMFR 201012 NWSheadline FIRE WEATHER WATCH REMAINS IN EFFECT FROM THIS AFTERNOON THROUGH SUNDAY MORNING FOR ABUNDANT LIGHTNING ON DRY FUELS FOR FIRE WEATHER ZONES 615, 616, 617, 618, 619, 620, 622, AND 623 BLOCKCHANNEL EAS BLOCKCHANNEL NWEM BLOCKCHANNEL CMAS VTEC /O.CON.KMFR.FW.A.0010.240721T0000Z-240721T1500Z/ eventEndingTime 2024-07-21T15:00:00+00:00
