Hurricanes are large circular storms that are formed over warm ocean water.
Hurricanes have winds that have a speed of 75 mph or more. The picture to the left shows a hurricane. Notice that the storm circulates around a central point in the center of the storm. This central point is called the eye of the storm.
Hurricanes form over the warm water of the Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico. They are most common during the summer months of August and September.
Changes in air pressure readings indicate shifts in weather patterns. A rising barometer typically signals increasing air pressure, often associated with fair weather, while a falling barometer suggests decreasing pressure, which can indicate approaching storms or inclement weather. These variations help meteorologists predict short-term weather conditions and can influence local climate patterns.

Decreasing air pressure typically indicates that a low-pressure system is moving into an area, which can lead to stormy weather. As air pressure drops, it allows for rising air, which can create clouds and precipitation. This process often results in storms, including rain, thunderstorms, or even severe weather conditions. Thus, a decrease in air pressure is often associated with the potential for unsettled and stormy weather.
Hot air tends to have lower pressure than cold air. This is because as air heats up, its molecules move faster and spread out, decreasing the air density and resulting in lower pressure.

decreasing
When the pressure is decreasing, what is likely happening is that air mass is getting less stable. So if the trend continues, expect the weather to become more unsettled. This could mean an increase ins surface winds, more clouds in the sky, or may precipitation may occur in the near future.

This is an indication that the air pressure is decreasing.

Altitude affects density and pressure by decreasing when it increases.
