Yes. Bar-b-que/outdoor cooking is allowed during red flag warnings. According to the National Weather Service (NOAA), a Red Flag Warning means warm temperatures, very low humidities, and stronger winds are expected to combine to produce an increased risk of fire danger.

Also, according to Wikipedia, a red flag warning is a forecast warning issued by the United States National Weather Service to inform area firefighting and land management agencies that conditions are ideal for wildland fire combustion, and rapid spread.[1] After drought conditions, when humidity is very low, and especially when there are high or erratic winds which may include lightning as a factor, the Red Flag Warning becomes a critical statement for firefighting agencies. Red flag warnings don’t necessarily indicate local fire restrictions.
Albany County Fire Warden enacts restrictions on burning within the county, and restrictions don’t always indicate a full-on fire ban.
Restrictions are typically accompanied by guidelines such as “fire must be supervised at all times” and “must have a means of extinguishment on hand” and other requirements.
