The IMD added that the post-monsoon rains have been reported in the national capital due to a western disturbance and that the easterly wind phenomenon is the reason behind very high moisture incursions from the Arabian Sea that has spread from Gujarat, Rajasthan, Uttarakhand and Delhi, resulting in rains.

Explaining further, an IMD official said the western disturbances which always move towards the west make rain and clouds move Northeastwards to Uttar Pradesh or Bihar, reported PTI. He added that in order to sustain rains for two days, the winds have linked from the Arabian Sea which is what is happening. Such intense interactions are mostly found from October to March.
