This means that forecast weather conditions combined with existing ozone levels are expected to result in local maximum 8-hour ozone concentrations that pose a health risk. Adverse health effects increase as air quality deteriorates. Ozone is an air contaminant which can cause breathing difficulties for children, older adults, as well as persons with respiratory problems. A decrease in physical activity is recommended. You are urged to car pool, telecommute, or use mass transit. The use of gasoline-powered equipment should be reduced or done late in the day.

Visit ready.gov/plan for more information. A Red Flag Warning is issued when we identify weather conditions that promote rapid spread of fire which may become life- threatening. This does not mean there is a fire. These conditions are either occurring now or will begin soon. It is important to have multiple ways to receive information from authorities.

Description: ...HIGH ABUNDANT LIGHTNING RISK WITH THUNDERSTORMS TODAY... ... WINDY AND BREEZY WITH CRITICAL RH FRIDAY AND SATURDAY...

Brief heavy downpours, gusty outflow winds in excess of 45 mph, small hail, and frequent lightning will be possible. A strong to briefly severe thunderstorm cannot be ruled out this afternoon and early evening. Friday the upper level low will eject into the region bringing windy conditions to many of the Cascade Gaps as well as central OR. Humidities both Friday and Saturday will be critical. * AFFECTED AREA...Fire Weather Zones 694 Grande Ronde Valley of Oregon, 695 Eagle Cap Wilderness and 699 Western Forested Blue Mountains. * TIMING...Until 8 PM PDT this evening. * IMPACTS...Any fire that develops will catch and spread quickly. Outdoor burning is not recommended. * THUNDERSTORMS...Isolated to scattered dry thunderstorms Thursday after 1200. * OUTFLOW WINDS...Gusts from 25-45 mph Instructions: A Red Flag Warning means that critical fire weather conditions are either occurring now, or will shortly. A combination of strong winds, low relative humidity, and warm temperatures can contribute to extreme fire behavior.

Thunderstorms will develop late Wednesday night and move from south to north across the area. * OUTFLOW WINDS...Any storms that develop will be capable of gusty and erratic outflow winds between 25 and 30 miles per hour. Outflow winds can occur ahead of and behind storms and cause erratic wind directions. * TEMPERATURES...Up to 77. * IMPACTS...Scattered lightning in dry fuels can cause multiple fire starts. Thunderstorms can also bring sudden sharp wind shifts on existing fires, causing rapid changes in a fire's rate of spread and direction of spread. Thunderstorm outflow winds can be a threat for several hours following the start of a new lightning-caused fire. If a fire were to begin, air quality may diminish in the surrounding area.

Thunderstorms will develop late Wednesday night and move from south to north across the area. * OUTFLOW WINDS...Any storms that develop will be capable of gusty and erratic outflow winds between 25 and 30 miles per hour. Outflow winds can occur ahead of and behind storms and cause erratic wind directions. * TEMPERATURES...Up to 77. * IMPACTS...Scattered lightning in dry fuels can cause multiple fire starts. Thunderstorms can also bring sudden sharp wind shifts on existing fires, causing rapid changes in a fire's rate of spread and direction of spread. Thunderstorm outflow winds can be a threat for several hours following the start of a new lightning-caused fire. If a fire were to begin, air quality may diminish in the surrounding area. Instructions: A Red Flag Warning means that critical fire weather conditions are either imminent or occurring now. Any fires that develop will likely spread quickly.
