LAHORE: Mist hung in and around Lahore in the early morning hours of Friday, with the Met Office saying more was expected as the days grew colder in December.
“As humidity decreases and the weather gets colder, more of this mist called fog is expected and we can often see it early in the morning,” a Met Office spokesperson told Dawn.
“The fog will increase except when rainfall occurs, or a northwesterly wind blows. Fog usually occurs when visibility is less than 1km; on Friday morning at Lahore airport it was around 100 metres.”
In the coming days there is no rainfall expected across the province of Punjab.
