The adverse weather is likely to impact millions of women observing the Karwa Chauth fast, as the moon sighting is a crucial part of the festival. Thunderstorms, lightning, and hail pose risks to those participating in outdoor rituals, such as moon-watching on terraces or in open spaces. Gusty winds of 30-40 km/h may also cause damage to loose objects and increase the risk of falling trees and power lines. The persistent cloud cover is expected to obscure the moon, creating uncertainty for those observing the festival.
