Karnataka is currently facing a severe heatwave, with temperatures soaring close to 45°C. The India Meteorological Department (IMD) has issued alerts for heavy rainfall and hailstorms expected to begin on April 20, particularly affecting coastal districts like Dakshina Kannada, Udupi, and Uttara Kannada. This weather shift is attributed to increased air pressure over the sea, which will likely bring thunderstorms and strong winds over the next few days. Hill districts such as Kodagu and Chikkamagaluru may also see sudden weather changes, raising concerns for farmers cultivating sensitive crops like coffee and mango. In North Karnataka, areas like Belagavi and Vijayapura are predicted to receive moderate to heavy rainfall, providing some relief from the ongoing heat. Meanwhile, Bengaluru and parts of South Interior Karnataka may experience cloudy conditions with light showers expected later. Authorities are urging residents, especially vulnerable populations, to avoid outdoor activities during peak heat hours and to take necessary precautions against heat-related illnesses. The unusual combination of extreme heat and sudden storm activity necessitates caution among residents as they navigate these changing weather conditions.
