It might be a foggy drive to work in the morning, which is actually like driving into a cloud – because that’s what it is.  It’s also a sign that there’s a lot of melting going on and foggy overnight periods stretch well into the mornings at this time of year.

You see,  the moisture rising from  melting snow quickly turns into water vapor, very fine mist, that makes up the cloud. The cloud basically forms at ground level  because of a cool layer of air from the snow pack . With the right conditions such as little to no wind, warming air coming in and a thick snow pack on the ground, that fog can become very dense and that could lead to hazardous driving conditions.

Fog advisory in effect for:

  • Agawa – Lake Superior Park
  • Sault Ste. Marie – St. Joseph Island
  • Searchmont – Montreal River Harbour – Batchawana Bay

Near zero visibility in fog is expected or occurring.

Dense fog will develop this evening. The fog will persist into Thursday, becoming patchy in the afternoon.

If travelling, be prepared for areas of near-zero visibility. If visibility is reduced while driving, turn on your lights and maintain a safe following distance.
