What's Typhoon Yagi? The rare meteorological occurrence behind delayed rainfall in UP

September has been unusually rainy across Lucknow and much of North India. According to the meteorological department, this surge in rainfall can be attributed to the remnants of Typhoon Yagi, the strongest storm to hit Vietnam in 30 years.

Typhoon Yagi, which originated in the Central Pacific, travelled thousands of kilometers, affecting weather patterns across Asia. As it weakened, the storm’s remnants interacted with the monsoon system, resulting in the delayed monsoon that is currently drenching parts of North India, especially Uttar Pradesh.

This late-season rain has been a welcome relief for regions like East UP, West Bengal, Bihar, and Jharkhand, which had been facing significant rainfall deficits. The extended rains are helping these areas recover from the shortfall, providing much-needed water for agriculture and reducing the impact of drought-like conditions.

By bringing delayed rains, Yagi has inadvertently aided regions dependent on the monsoon for their agricultural needs.
