The India Meteorological Department (IMD) has issued a thunderstorm and lightning alert for various states, including Tamil Nadu, Telangana, and Delhi-NCR. These storms are expected to bring gusty winds of 40-50 kmph and pose risks such as lightning strikes, falling trees, and power outages. The IMD emphasizes the dangers associated with lightning, which can cause severe injuries or fatalities, particularly in open spaces or near tall structures. To ensure safety, individuals are advised to move indoors at the first sign of thunder or lightning, avoid seeking shelter under trees, and stay away from open fields and water bodies. Additionally, unplugging electrical devices and avoiding wired electronics during storms is recommended to prevent damage from power surges. For those caught outdoors, finding shelter quickly is crucial, and if none is available, crouching low with feet together can minimize risk. The IMD also warns of heavy rainfall in coastal areas, raising concerns about waterlogging and other weather-related hazards.
