Heavy rainfall in Uttarakhand, particularly in districts like Pithoragarh, Chamoli, and Rudraprayag, poses risks for pilgrims undertaking the Char Dham Yatra. Bihar and Jharkhand may experience thunderstorms and lightning, affecting cities such as Patna, Ranchi, and Dhanbad. Strong winds reaching up to 50 kmph are expected in eastern Madhya Pradesh, potentially disrupting daily activities. Delhi's moderate to poor air quality could exacerbate respiratory issues for vulnerable populations. Flooding and waterlogging risks are heightened in areas receiving heavy rainfall.
