Monsoon trough shifts north, brings rain boost and flood fears
The monsoon trough, a key driver of India's monsoon system, has now shifted northwards, signalling a significant change in rainfall distribution across northern and central India. Meteorologists expect this shift to intensify rainfall activity across several regions in the coming days, raising hopes for farmers and concerns about potential the trough stabilises in its new position, all eyes are on Delhi and surrounding regions to see whether they too will receive much-needed rainfall in the days monsoon trough is an elongated zone of low pressure stretching from northwest India to the Bay of Bengal. This dynamic feature plays a crucial role in the Indian monsoon by aiding moisture convergence and triggering convective storms. As it oscillates north and south during the season, it directly impacts the timing and intensity of rainfall across the country. This current northward movement of the trough has already enhanced moisture inflow and convective activity. As a result, forecasts now indicate heavy to very heavy rainfall over northwest, central, east, and northeast India over the next week. States like Punjab, Haryana, Uttar Pradesh, and Bihar stand to gain from this surge, with improved soil moisture expected to benefit rain-fed agriculture and bolster crop this increase in rainfall also brings risks. Low-lying regions with poor drainage systems may face flooding and waterlogging, complicating both urban life and rural factors appear to have influenced the shift. An early onset of monsoon, driven by a persistent low-pressure area over the Arabian Sea and a trough over Vidarbha, ramped up moisture levels in the climate patterns such as neutral ENSO conditions, a stronger Mascarene High, and reduced Himalayan snow cover have also supported the monsoon's a low-pressure system forming over the Bay of Bengal is drawing the trough further north by attracting atmospheric moisture and energy.- EndsMust Watch IN THIS STORY#Delhi

Hot and humid with a chance of showers from Tuesday: IMD
Mumbai: The hot and humid weather will prevail in the city this month, but there's a possibility of thunderstorms too. The India Meteorological Department (IMD) has forecast thunderstorms and rainfall in several districts, including the adjoining Thane and Palghar, beginning May 6, bringing potential relief from the sweltering conditions that have gripped the state. IMD scientist Sushama Nair said the heat, coupled with humidity showing moisture in the air, is indicative of the monsoon setting in. "This is a normal feature every May, ahead of the first week of June," she explained.

Mumbai's temperature will remain around 35C due to moist westerly winds from across the coast, said Nair, adding that such weather suggested that larger phenomena, li-ke Mascarene High, heat low, and jet-stream, which are resp-onsible and indicative of monsoon activation, are working. On Friday, the maximum temperatures recorded by IMD's Santacruz and Colaba observatories were 34.4C and 34.2C, respectively, even as several locations across Maharashtra sizzled with temperatures hitting or surpassing 40°C. Akola recorded the highest temperature in the state at a scorching 44.9°C. Solapur recorded 44.7°C, Jalgaon 43.9°C, Pune's Lohegaon area 43.2°C, Satara 40.9°C and Shivajinagar 40.6°C. IMD Pune scientist SD Sanap explained that hot conditions were caused by an anti-cyclonic circulation over the region, which is now dissipating. "Westerly winds from the Arabian Sea will be penetrating the region, bringing moisture at upper levels, while we are also getting winds from the Bay of Bengal at lower levels. This is likely to create atmospheric instability which will cause convective rain in the coming days," he said. According to IMD's Regional Meteorological Centre Mumbai's five-day district forecast, Thane, Palghar, Raigad, Ahilyanagar, Ghats of Pune, Nashik, Satara, Chhatrapati Shambhajinagar, Jalna, and Beed among others will experience thunderstorms accompanied by lightning, with light to moderate rain and gusty winds reaching 30-40 kmph at isolated places from May 6.
