At last, some signs of activity in the Northern Arabian Sea and the Pacific Ocean (27Jun2022)

When queried, a senior meteorologist had this explanation:

                            Deep trough in upper troposphere at 18Z/22Jun2022👆
This is La Nina year. When Equatorial Pacific will be unusually cool and equatorial Indian Ocean will be warm to give rise to good monsoon.
Lows help transporting energy from lower latitude to higher latitude. Currently the deep troughs associated with Western Disturbances is doing the job. In this low zonal Index phase chances of low formation will be less but deep trough activity will be more.

Update on 28Jun2022
JTWC had yesterday issued an ORANGE warning on storm 94A in the North Arabian sea which meant that it was likely to develop into a cyclone. Today, they have removed 94A altogether as such the entire northern Indian Ocean remains placid and calm - no low, depression or cyclone likely to form.
