Which weather change could indicate an approaching hurricane?

A significant drop in atmospheric pressure is indeed a strong indicator of an approaching hurricane. This phenomenon occurs because hurricanes are characterized by a low-pressure center. As a hurricane approaches, the atmospheric pressure in the area decreases markedly, which can be measured using barometers. The drop in pressure can often be observed a day or two before the storm makes landfall, giving crucial information about its proximity and potential intensity.

In contrast, a rapid increase in temperature is not a typical precursor of hurricanes and does not provide weather-related signals that would predict such an event. Similarly, decreasing humidity levels are more commonly associated with fair weather and do not indicate the moisture-laden environment typical of hurricanes. A sudden change in footing conditions may suggest local disturbances or flooding but doesn’t relate directly to the broader atmospheric changes associated with an approaching hurricane.
