Weather delays occur when adverse weather conditions, such as heavy rain, snow, fog, or thunderstorms, disrupt scheduled activities, particularly in transportation. These delays can affect flights, trains, and even road travel, leading to cancellations or extended wait times for passengers. Airlines and transportation companies monitor weather forecasts to ensure safety. When conditions are deemed unsafe, they may delay or reroute services. Travelers are often advised to check for updates and plan accordingly, as weather delays can lead to significant disruptions in travel itineraries.
