May has brought unusually intense pre-monsoon rainfall across parts of Maharashtra, creating monsoon-like conditions much earlier than expected. On Tuesday alone, Chinchwad recorded the highest rainfall at 80mm, followed by Lavale (34.2mm), Lohegaon (33.8mm), Shivajinagar (23.6mm), and Koregaon Park (5.5mm). The downpour, accompanied by thunder and lightning, led to severe waterlogging in several areas, disrupting daily life and traffic. The India Meteorological Department (IMD) attributed this unusual weather to the early setting of westerly winds and favorable global climate indicators such as the El Niño Southern Oscillation and Indian Ocean Dipole, which could result in an above-normal monsoon this year.
Independent weather forecaster highlighted that a strong Western Disturbance had extended unusually far south into the Arabian Sea, disrupting the typical high-pressure system and enabling significant moisture incursion. This, combined with a wind discontinuity and the early onset of the southwest monsoon over the Andaman and Nicobar Islands, has intensified pre-monsoon activity. The IMD has issued an orange alert for the ghats of Pune, Kolhapur, and Satara, and yellow alerts for Marathwada and Vidarbha, warning of heavy to very heavy rainfall, lightning, gusty winds, and the possible collapse of weak trees or structures in the coming days.
