Smoke From Canada's Wildfires Triggers Health Scare In US
Skies turned hazy, compromising the visibility. Wisconsin, Michigan, and Minnesota experienced concerning levels of air pollution this weekend.
Parts of Illinois and Indiana were also under air quality alerts, with authorities urging people to stay indoors or limit time spent outdoors, NPR reported.
In the Northeast, states including New York, Vermont, New Hampshire, and Maine are seeing smoke-related pollution, and officials warned residents against venturing outdoors.
The way wind moves through the atmosphere is making smoke from Canada's wildfires travel to the US, National Weather Service Lead Forecaster Bob Oravec told NPR.
The wind is blowing at many levels of the atmosphere, and in many cases, it's blowing in the same direction, he said.
As the wildfire smoke rises, it gets caught in these winds and is carried along, just like how a leaf gets blown by the wind, he explained.
The Minnesota Pollution Control Agency (MPCA) on Friday announced the statewide air quality alert and mentioned it would remain in effect until Monday, August 4, at noon. The smoke is expected to reach New York City on Monday, NBC reported.
The Air Quality Index (AQI) in the region is currently between 101 and 150, which falls under the 'Orange' category. According to the Pollution Control Board, this level of air pollution is considered unhealthy for sensitive groups.
Those at higher risk are senior citizens above 65, children under the age of 14, people with respiratory conditions such as asthma or bronchitis, and pregnant women.
The smoke from Canada's hundreds of wildfires is the primary cause of the pollution. This marks the state's longest air quality alert since 2008, according to Minnesota Public Radio (MPR). The entire duration of the alert is likely to be seven days.
The country has recorded almost 4,000 wildfires already this year.

Why is the air quality so bad in Las Vegas today? These neighborhoods have 'unhealthy' AQI
Several neighborhoods in Las Vegas, including Downtown, Angel Park, and Summerlin North, reported 'unhealthy' air quality levels on Monday, with hazy, smoky skies particularly affecting the western part of the valley. Las Vegas residents are reporting poor air quality.(UnSplash) What's causing the poor air quality? The poor air quality is primarily due to smoke drifting from the Gifford Fire burning near Santa Maria, California. Wildfire smoke has spread into the Las Vegas Valley, reducing visibility and increasing fine particulate matter (PM2.5) in the air. Current air quality readings As of 11 a.m. PDT, the average Air Quality Index (AQI) in Las Vegas stood at 184, which falls into the 'unhealthy' category according to AirNow. The worst AQI readings have been recorded in the following areas: Downtown Las Vegas – 184 AQI · Unhealthy Angel Park – 171 AQI · Unhealthy Summerlin North – 167 AQI · Unhealthy Rancho – 165 AQI · Unhealthy AirNow warns, 'Some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects.' Residents react to the smoky skies Many Las Vegas residents have taken to social media to express concern over the conditions. One person wrote on Facebook, 'Be careful out there Las Vegas that Grand Canyon fire is filling the air with smoke.' Another wrote, 'This is smoke, you can't see the mountains - our air quality is bad here in the Vegas. We need some wind - can I request a lake wind from WI/MN please - to blow it out of the Valley.' A third person reported, 'It is smoky out there, Vegas peeps, worse now than early this morning (I can even smell it now). If you're elderly or have respiratory issues, please consider staying indoors as much as possible. The usual strip view is completely smoky.' Another resident reported, 'Unbelievable! This is the air quality in in Las Vegas today! No wonder I felt so stuffy and having a hard time breathing this morning! Yikes!'
