Deep depression after crossing Odisha coast has moved northwestward. The intense weather system rolled over entire breadth of Odisha, including interiors parts, and is now marked over Chhattisgarh.
For the 2nd consecutive day, the depression left a spate of rainstorms drenching most parts of Odisha. The prominent amounts of rainfall being : Angul-202mm, Cuttack-120mm, Balasore-135mm, Chandbali-84mm, Keonjhargarh-64mm, Sambalpur-62mm and Bhawanipatna-60mm. The forward peripheral of the system also impacted Chhattisgarh and Vidarbha region.
The depression will move further northwest, albeit slowly and reach Madhya Pradesh in the next 24 hours. From this position, the weather system will have a large area of influence covering Madhya Pradesh, Uttar Pradesh, Vidarbha, Marathwada, East Rajasthan and Delhi.
Heavy to very heavy rainfall is expected at many places over these states in the next 48 hours. The proximity of this system to another low pressure over Gujarat will together enhance rainfall over the erstwhile most deficit state.
Weakened system as a low pressure will travel deep in to Rajasthan and lash the border areas also with wide spread rainfall. Prolonged stay of cyclonic circulation associated with the low pressure will extend the weather activity for nearly 3-4 days over that region between 17th and 21st Sep.
While centered over Rajasthan, the weather system will give rains over Haryana and Punjab, though mostly of moderate intensity. Northward shift of rain belt will take the weather activity deep in to hilly states of Jammu & Kashmir, Himachal Pradesh and Uttrakhand, at least for 3 days, from 19thSep to 21stSep.
The extended stay of this weather event will lead to delayed withdrawal of monsoon from the westernmost posts of Rajasthan. The cascading effect may trickle further to other parts of North India and Delhi. The Pan India rainfall deficiency lingering at 7% will drop to safe margin towards fag end of the season.
