Monsoon 2019 has had a delayed arrival this time initially, with Kerala only seeing the arrival on June 8, which is a week late. Monsoon remained sluggish, and weak thereafter resulting in very less rains over the region.
However, in the last few days, Monsoon was seen picking pace. In fact, until June 19, Southwest Monsoon had made an onset over just 20 percent of the country. By June 23, more than 50 percent of area saw Monsoon arrival with 17 states being covered fully, and Monsoon partially arriving over Maharashtra, Chhattisgarh and Uttar Pradesh.
During the next 48 hours, Monsoon will move further, covering entire Konkan and Chhattisgarh, entering parts of South Gujarat, and Madhya Pradesh and some more parts of Uttar Pradesh.
In West Madhya Pradesh, Monsoon will arrive over Indore, Ujjain, and Ratlam while it has already made an onset over Chhindwara, and Mandla
Monsoon progress takes place due to two branches, the western and the eastern, with the western being associated with the Arabian Sea and the eastern with the Bay of Bengal.
Southwest Monsoon in the first phase covers from south to north, with Kerala and West Coast including Maharashtra being covered via the Arabian Sea branch and Northeast India being covered by the Bay of Bengal branch. For the second phase, Monsoon covers east to west, with mainly Bay of Bengal advancing Monsoon over Bihar, Jharkhand, West Bengal and Chhattisgarh. Thereafter, in the third phase, both the branches act in tandem wherein the Monsoon arrives over Northwest India.
This time, unusually, the Bay of Bengal branch was more active wherein the Arabian Sea was silent, due to Cyclone Vayu, which made it quite sluggish. The Northern Limit started with Kannur then Mangaluru, and furthermore Ratnagiri, thereafter covering Alibag, staying just short of Mumbai.
The Low pressure area resulted in the revival of progress of Monsoon this year with the advancement speeding up. Now, the Arabian Sea branch is also picking up pace with Monsoon reaching Mumbai and southern parts of Gujarat as well in the next 48 hours.
Thereafter, the current low pressure area will lose its current, thereby slowing the progress of Monsoon once again. Therefore, Northwest India including Delhi and the NCR region may have a delayed onset.
