IMD Director General Mrutyunjay Mohapatra said the conditions are ripe for the advancement of the Southwest Monsoon over Delhi as humidity has also increased due to easterlies. He said the formation of a low-pressure area will also boost its advancement.
However, there have been several instances this season when the IMD got its monsoon forecast for Delhi and nearby regions wrong, leaving the area high and dry.
At present, Delhi is the most rain-deficient district in India. Overall, Delhi has received 64% less rainfall than normal, so far.

The weather department has also issued alerts for several north Indian states and a red warning for coastal Maharashtra.
