Which of the following weather conditions is indicated by a sudden fall in barometer reading ?

A sudden fall in the barometer indicates a rapid drop in atmospheric pressure and typically signals the approach of a low‑pressure system or depression, which brings unstable conditions such as clouds, wind, rain or storms [1]. Meteorological references note that severe storms appear as deep, wide dips on a barograph and that falling readings often presage rain or storms, while rising readings generally indicate fair, improving weather [1]. Textbook pressure thresholds also link pressures below about 1000 mb with depressions, supporting that a sharp barometric decline corresponds to stormy or disturbed weather [2]. Thus, the best choice among the options is 'Stormy weather.'
