MOSES LAKE – The fires below are burning nearly 139,000 acres across Washington as of Thursday afternoon. This is around 9,000 acres more than Monday and 29,000 more acres than last Thursday.  

Fires that showed a lot of growth over the week include the Lower Sugarloaf Fire, which grew around 3,000 acres, making it the largest fire in the state. The Labor Mountain Fire also had growth of around 7,000 acres from Monday to around 17,000 acres as of Thursday.  

These fires were causing air quality concerns regionally. As the Columbia Basin goes into the weekend, there are several cities where the air quality is unhealthy for sensitive groups until Monday.  

According to the United States Environmental Protection Agency, sensitive groups include people with lung or heart disease, older adults, children, teenagers, pregnant women, minority populations and outdoor workers.  

When the air quality is unhealthy for sensitive groups EPA recommends making outdoor activities shorter and less intense. It also recommends watching out for symptoms such as coughing or shortness of breath. For those with asthma, be sure to keep medicine readily available. For those with heart disease, if symptoms such as palpitations, shortness of breath or unusual fatigue happen, EPA recommends reaching out to a health care provider.
