The southwest monsoon has fully set in across India, beginning its four-month rainy season with significant rainfall in South and Northeast regions. The India Meteorological Department (IMD) has reported that the monsoon has advanced into several states, including Kerala, Tamil Nadu, Karnataka, and parts of the Northeast like Mizoram and Manipur. Heavy rain alerts have been issued, particularly in Kerala, where a red alert is in effect for five districts due to expected intense rainfall and strong winds. In the National Capital Region, pre-monsoon rain has provided temporary relief from the heat, although temperatures are expected to remain high, nearing 40 degrees Celsius. Rajasthan may see a resurgence of heatwave conditions after a brief period of cooler temperatures. Meanwhile, Tamil Nadu is also on alert for heavy rain and thunderstorms, with warnings for fishermen to avoid venturing into rough seas. Overall, the IMD anticipates further advancement of the monsoon into new areas in the coming days, highlighting the need for caution in affected regions.
