Sudden weather changes refer to quick shifts in atmospheric conditions that can occur within a short period. These changes can include unexpected rain, temperature drops, or strong winds. Factors such as cold fronts, warm fronts, and thunderstorms can contribute to these rapid transitions, often catching people off guard. Such weather changes can impact daily activities and safety. For instance, a sunny day can quickly turn into a stormy one, leading to potential hazards like flooding or lightning. Being aware of local weather forecasts and using tools like weather apps can help individuals prepare for these unpredictable conditions.
