It could not have been a better goodbye to the Monsoon season, than this. Monsoon surge revived during the last 15 days, deluging more than 17 states of the country. All thanks to Cyclone Daye, which though lasted for a short duration but was strong enough to give the rains over the entire country, barring parts of extreme southern parts.
It all started with a cyclonic circulation, which saw rapid intensification from low pressure area over west central Bay of Bengal to a tropical storm over north central Bay of Bengal. It crossed Odisha coast as a cyclonic storm but shortly weakened into a deep depression, bringing heavy to extremely heavy rains initially over Odisha, Coastal Andhra Pradesh, West Bengal, and Jharkhand.
The system then travelled towards Central India bringing torrential rains over Chhattisgarh, East Madhya Pradesh and Maharashtra. Peripherals of the system also covered Telangana, North Interior Karnataka and Rayalaseema.
In the third phase, system as a well-marked low-pressure area headed towards further west, giving heavy rains over Gujarat, East Rajasthan and adjoining West Madhya Pradesh. During this time, the system started interacting with a Western Disturbance over Jammu and Kashmir, leading to fairly widespread rain and thundershowers over entire Northwest India.
While Himachal Pradesh, Uttarakhand and Punjab saw heavy to extremely heavy rainfall, rest of the plains of Haryana, Delhi-NCR and Uttar Pradesh recorded moderate to heavy rainfall.
According to weathermen, the last spell of rainfall over Northwest India has been more intense, triggering flash floods and series of landslides and mudslides. This was because whenever two weather systems move tandem, they tend to support each other and slowdown each other’s pace. This results in prolonged and intense weather activity.
Cyclone Daye has been instrumental in improving the rainfall deficiency across most parts of the country. Following table would give you a better insight.
Now, this low pressure area which is over Haryana, Delhi and adjoining Uttar Pradesh, is all set to fizzle out. However, the system would continue to give rains over Himachal Pradesh, Uttarakhand, Delhi, Northwest Uttar Pradesh, Punjab and Haryana till Tuesday.
Thereafter, rains would vacate this region, in fact from most parts of the country.
