UPDATE: A fog advisory has ENDED for the Parry Sound Area.

A Fog advisory has been issued for the Parry Sound area as Environment Canada says near zero visibility is expected later tonight or is already occurring in some parts of the region.

The agency says it expects winds will also become light this evening.

With all the moisture on the ground from the recent rain, conditions are favourable for the formation of fog.

Widespread fog is expected to continue well into Sunday morning and then should dissipate by around noon.

Visibility may be significantly and suddenly reduced to near zero.

Travel is expected to be hazardous due to reduced visibility in some locations.

If visibility is reduced while driving, slow down, watch for taillights ahead and be prepared to stop.

If you wish report severe weather, send an email to ONstorm or tweet reports using #ONStorm.
