The unseasonably warm temperatures and low humidity in the valley is adding fuel to the fire causing more air pollution. Doctors are recommending those with asthma or allergies to avoid the outdoors. But some aren't exactly following doctors orders.
Just off of Highway 180 in Fresno County you can see the smoke from the sheep fire appearing as a haze in the hills. Forest officials at headquarters are working to contain the fire which re-ignited Friday.
"Local community residents should certainly expect to see smoke, especially if you're in Cedar Grove and the Hume Lake community. Where those levels can be high enough that people who are sensitive to smoke really should be cautious about going there," David Bartlett said.
Hazy conditions could also be seen from Downtown Fresno.
With temperatures in the mid 90s, doctors say smoke added with the heat can equal big health problems for some residents.
"The more you end up with the high pressure overhead causing us to be like a bowl, the more the fire burns the more smoke. The dirtier it gets," Dr. William Ebbeling said.
At Woodward Park in northeast Fresno some soccer players weren't aware of the added air pollution from the sheep fire.
Gustav Rojas says despite his health being at risk he wants to play and avoid the sidelines. "No, I mean if you really like something and you enjoy playing it, you actually pursue it and keep playing regardless you know."
Dr. Ebbeling adds air quality is at its worst late in the afternoon when the sun goes down.
According to the San Joaquin Valley air pollution control district most Central Valley counties are listed in the unhealthy for sensitive groups category for Sunday.
