Just arrived in KHI yesterday. My journey commenced around 11:30 AM from ISB. I first planned to make a stop at RYK in case the fog get dense, leaving me with no option but to stay. However, upon reaching RYK, I found the weather to be better compared to the cities I had just passed.
The weather remained clear from RYK to Sukkur, particularly after Sadiqabad. I decided to stay in Sukkur due to the late hour and resumed my journey around 8 AM the next morning from Sukkur to Karachi. The weather was foggy throughout, although not densely, with visibility averaging around 100 meters. It was in Gambat where the fog became denser. However, just before Moro, everything cleared up.
For those planning to travel, it's advisable to do so during the day. The Multan-Sukkur motorway, at times, doesn't open until 1 PM.
