An air quality health advisory will be expanded to include all of New York with more smoke from Canadian wildfires reaching the state, Gov. Kathy Hochul on Wednesday said. 

New York will be using a first-time emergency alert system that will issue notifications when the air quality index for an hour exceeds the 200 threshold, considered "very unhealthy" air, Hochul said. 

"With smoke from the Canadian wildfires once again impacting air quality throughout our state this week, we're urging New Yorkers to remain vigilant," Hochul said. "We're activating emergency cell phone alerts to ensure New Yorkers have the latest information and are continuing to coordinate with local counties to monitor conditions and distribute masks. I encourage all New Yorkers to stay informed about the latest updates and take the necessary precautions to protect yourselves and your loved ones."

Parts of New York are seeing poor air quality on Wednesday after smoky conditions engulfed many parts of New York earlier this month from the same wildfires. 

Health officials have recommended people with underlying health and respiratory conditions wear masks outside when the air quality is considered poor. 

"DEC expert meteorologists have updated the forecast for today as the plume progresses further east," said Environmental Conservation Commissioner Basil Seggos. "We will continue to keep the public informed of the significant near surface smoke impacts expected statewide as conditions change."
