In past, East India particularly East Uttar Pradesh and Bihar were reeling under the spell of dense to very dense fog. However, many areas observed clear sky conditions today as well.

In wake of this, humidity levels have come down signifivantly and wind speed has also increased marginally. These factors together have kept fog remain abated in North and East India.
The central parts of the country have also observed fog free morning today.
As far as South india is concerned, Bangalore in Karnataka has witnessed moderate fog with the visibility dropping to 400 metres due to localized phenomenon. This is only for a short period, conditions are likely to improve once sun comes up.
