The UK is experiencing a dramatic weather shift from the year's hottest day to heavy rains and possible thunderstorms, particularly in the south and southwest regions. India is also under severe weather alerts, with heavy to extremely heavy rainfall predicted in Maharashtra, Gujarat, Goa, and other states over the weekend, prompting red and orange alerts from the IMD. Mumbai and Mangaluru are particularly affected, facing severe waterlogging and traffic disruptions due to incessant rains. In Kerala, authorities have urged residents to remain vigilant amid forecasts of heavy rains and strong winds. Additionally, rising humidity and damp conditions have led to an increase in asthma and other respiratory issues during the monsoon season in India.
