The India Meteorological Department has issued heat-wave alerts for Delhi, Uttar Pradesh, and Rajasthan as the southwest monsoon slows [1, 2].
This weather shift is critical because the monsoon provides the primary water source for India's agriculture and cooling relief from extreme summer temperatures. A delay or slowdown in these rains can lead to crop failure and public health crises related to heat exhaustion.
While the monsoon reached Kerala early this year [1], its progress toward the north has stalled. The India Meteorological Department said that the slowdown is affecting several regions, including Haryana, Maharashtra, and Gujarat [1, 2]. The lack of precipitation has left northern states vulnerable to spiking temperatures.
Meteorologists have analyzed the atmospheric conditions contributing to this pattern. Experts said the slowdown is linked to a weak Somali Jet, a low-level wind current that typically helps push moisture from the Indian Ocean toward the mainland [2].
Changing weather patterns have disrupted the expected timing of the rains. This atmospheric instability has created a gap in the seasonal transition, allowing heat-waves to intensify in the northern plains [2].
Local authorities in the affected states are monitoring the situation as they wait for the monsoon to resume its northward trajectory. The India Meteorological Department continues to track the Somali Jet's strength to predict when the relief of rainfall will arrive in the heat-stricken regions [1, 2].

The disruption of the Somali Jet highlights the fragility of the Indian monsoon system. When these atmospheric currents weaken, the resulting delay in rainfall creates a dangerous window where extreme heat and drought conditions overlap, potentially stressing the national power grid and agricultural output before the rains finally arrive.
