The India Meteorological Department (IMD) has announced that the ongoing intense rainfall spell over the west coast, particularly in the regions of Konkan, Goa, and Gujarat, is expected to reduce from Friday. However, rainfall activity is likely to increase over northern parts of the country from July 9. The current weather patterns have been influenced by several atmospheric phenomena, according to meteorologists. The monsoon trough, which is the band of low pressure that typically brings heavy rains, is currently positioned south of its normal location. Additionally, an east-west shear zone is running roughly along South Peninsular India.
Furthermore, an off-shore trough at mean sea level extends from the south Gujarat coast to the north Kerala coast. These factors, combined with the presence of cyclonic circulations over Gangetic West Bengal and adjoining north Odisha, as well as the northeast Arabian Sea adjoining the Gujarat coast, have led to a surge in monsoon activity over the west coast and north India. Weather experts predict that intense rainfall will continue over the west coast for another two days due to a significant monsoon surge in the region. A cyclonic circulation over north Pakistan and Punjab, along with the monsoon trough’s southern position, is bringing easterly winds from the Bay of Bengal.
Furthermore, a cyclonic circulation over Gujarat is contributing to southwesterly winds from the Arabian Sea. These combined conditions create a favorable environment for widespread rain over north and northwest India, spanning from Uttarakhand to Punjab, Haryana, and Delhi, as well as the Indo-Gangetic Plains, for the next five days. Additionally, a weak western disturbance impacting the Western Himalayan region is expected to further enhance rainfall in the area. Over the next two days, the South Peninsular region can anticipate light to moderate widespread rainfall, with isolated instances of heavy to very heavy rainfall.
Northwest India is likely to experience moderate, fairly widespread to widespread rainfall, with isolated heavy rainfall over the next five days. Uttarakhand and East Rajasthan may also face isolated instances of very heavy rainfall during this period, while West Uttar Pradesh can expect similar conditions over the next two days. Central India should anticipate light to moderate, fairly widespread rainfall over the next two days, followed by a reduction in activity.
In the eastern and adjoining northeastern regions of India, widespread light to moderate rainfall, with isolated heavy to very heavy rain, is expected over Sub-Himalayan West Bengal, Sikkim, Assam, Meghalaya, Arunachal Pradesh, Nagaland, and Manipur in the next five days. Odisha and Bihar may experience isolated heavy rainfall over the same period. As weather patterns continue to evolve, it is important for residents and authorities in these regions to stay updated with the latest forecasts and take necessary precautions to mitigate the impact of heavy rainfall.
