A MODIS satellite image posted on Twitter by meteorologist Kelly Butt, showing a trail of smoke over Newfoundland from forest fires in Quebec. According to NASA. MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites.

Smoke from forest fires in Quebec is expected to persist over Newfoundland today, according to the latest air quality statement issued by Environment Canada and the provincial Department of Environment and Conservation.

The advisory says most of the smoke is confined to the upper atmosphere giving the sky a hazy appearance. "It is possible that a perceptible odour of smoke may be detected at ground level as air quality health index (AQHI) levels have risen slightly as a result of the forest fire smoke."

It was expected that the smoke would blow out to sea today, but that hasn't happened yet.

The area that currently appears to be affected the most is western Newfoundland. Today, the maximum AQHI in Corner Brook is four or moderate risk, according to Environment Canada and the provincial Department of Environment, dropping to three tonight and two on Tuesday.

The forecasted AQHI values for areas on the island are as follows:
