IndiGo issued a travel advisory for its passengers on Wednesday, amid predictions of heavy rains in Mumbai and its surrounding areas.

According to the advisory, the heavy rains could lead to air traffic congestion, which could impact flight operations.

"While we want your journey to be as hassle-free as possible, Mother Nature has her own plans. With heavy rains expected again in Mumbai, there's a chance this could lead to air traffic congestion and impact flight operations," the advisory said.
