Thick fog is hanging over the southeast Wednesday morning, making for challenging highway travel.

The province's Highway Hotline cites reduced visibility on highways in the Estevan area as of updates posted shortly before 5 a.m.

"Near zero visibility in fog is expected or occurring," said a Environment Canada advisory. "Dense fog is being reported in parts of southern Saskatchewan this morning. The fog will lift later today, but will likely redevelop tonight.

"If travelling, be prepared for areas of near-zero visibility. If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop."
