Punjab is in the normal bracket so far and is within plus-minus 10% while Haryana is deficit and is in the bracket of 25 to 30%.
The last two days have been quite silent for these two regions hence leading to rise in the deficiency levels. In the first five days of August, a mixed scenario was seen. By this, we mean that the first three days showers of rain over these states were fairly okay and in the last two days it was almost a dry weather with isolated spells in pockets. Like for instance, yesterday, Punjab recorded 0.3 mm of rains against the normal of 5.9 mm while Haryana witnessed 1.3 mm of rains against the normal of 6 mm.
This is generally the peak period of rains for these states. This region generally witnesses rains due to the oscillation of the Monsoon Trough. This oscillation of Trough is because of the Western Disturbance which induces a Cyclonic Circulation either over Central Pakistan or Rajasthan or over Punjab.
The Monsoon Trough needs some trigger for its oscillation. Thereby, if the Monsoon Trough gets stagnant, then the rainfall activities become minimal.
As per the experts, in the next 48 hours, fairly widespread rains with light to moderate in nature will be seen all along the foothills of Punjab and Haryana. The plains of these regions can also see rainfall activities. Places like Pathankot, Gurdaspur, Ropar, Chandigarh, Anandpur Sahib, and Nangal in Punjab along with Ambala and Yamunanagar in Haryana will see these rainfall activities.
The areas close to the proximity of Delhi might see more showers and they will be of moderate nature. These rains are in the wake of an upper air system which is prevalent over the northern parts of Pakistan and has induced a Cyclonic Circulation over parts of Pakistan and adjoining Punjab. Also, the Monsoon Trough is running from this circulation to the Depression in the Bay of Bengal. During this time, thunderstorms can also be a sight.
It is likely that post 48 hours, isolated activities will continue over the region. However, these rains won’t be of much help in pulling down the deficiency figures substantially.
