Another day passed Tuesday as smoke remained in Lodi and throughout the San Joaquin Valley.
That brown haze, caused by a number of fires burning in Northern California, isn't expected to go anywhere in the immediate future, if wind forecasts hold up.
The heavy smoke and particulate pollution prompted the San Joaquin Valley Air Pollution Control District to issue a warning on Tuesday morning declaring the air in the central region "unhealthy for everybody."
Officials are urging residents with asthma and other respiratory ailments to stay indoors and limit outdoor activity. Exposure to particulate pollution can cause asthma attacks and acute bronchitis.
Despite the warnings, several local baseball teams kept to their schedules Tuesday playing in the haze.
Firefighters did make progress overnight on the blazes, including one in Napa and Solano counties that is likely causing to most of Lodi's haze.
But winds are expected to remain as they have - about 8 to 10 mph from the west - until Thursday night, according to private forecasting firm AccuWeather.com. As of late Tuesday afternoon, the forecasting service was predicting the wind to shift to the south around 9 or 10 p.m. Thursday.
The National Weather Service was predicting smoke to remain until 11 p.m. Thursday.
A wind shift would move the smoke out of the valley, bringing in southern air from the less smoky half of the state.
Fire control is also a factor in the amount of smoke drifting through the air, and by Tuesday morning the "Wild Fire" near Fairfield had been 80 percent contained. By 7:30 p.m. the fire had burned 4,089 acres, according to the California Department of Forestry and Fire Protection (CAL Fire) and is being fought by 540 firefighters.
Wildfires raging across California are being blamed for unhealthy air quality throughout the San Joaquin Valley.
