990 to 1010 millibars. Lowest barometric pressure
Pressure and Winds the distribution across a hurricane. Atmospheric pressure and wind speed change across the diameter of a hurricane. To demonstrate, the diagram below shows a rough profile of wind speed (blue) and surface pressure (red) across a hurricane. Between 100 and 200 kilometers from the eye, the winds are fast enough to qualify as tropical storm force. The atmospheric pressure here will still be relatively high compared to the storm's center at about 990 to 1010 millibars. The most recognizable feature found within a hurricane is the eye. They are found at the center and are between 20-50km in diameter. The eye is the focus of the hurricane, the point about which the rest of the storm rotates and where the lowest surface pressures are found in the storm. The image below is of a hurricane (called cyclone in the Southern Hemisphere). Note the eye at the center. Image by: OSEI. Skies are often clear above the eye and winds are relatively light. It is actually the calmest section of any hurricane. Weaker or disorganized storms may also feature an eyewall that does not completely encircle the eye or have an eye that features heavy rain. In all storms, however, the eye is the location of the storm's minimum barometric pressure-the area where the atmospheric pressure at sea level is the lowest. There is, however, very little wind and rain, especially near the center. This is in stark contrast to conditions in the eyewall, which contains the storm's strongest winds. Due to the mechanics of a tropical cyclone, the eye and the air directly above it are warmer than their surroundings. The eye of the hurricane is an area of low pressure, generally  below 995 millibars. This may seem somewhat counterintuitive, as  air sinks in the eye of a hurricane, which … is more typical of high  pressure than low pressure. The eye of a hurricane is a calm area at the hurricane's center of rotation. It is free of rain and may be free of clouds. The eye wall of a hurricane is an area of intense co … nvection just outside the eye where the strongest winds occur. Best Answer: The eye is a region of mostly calm weather found at the center of strong tropical cyclones. The eye of a storm is a roughly circular area and typically 30–65 km (20–40 miles) in diameter. It is surrounded by the eyewall, a ring of towering thunderstorms where the most severe weather of a cyclone occurs. The cyclone's lowest barometric pressure occurs in the eye, and can be as much as 15% lower than the atmospheric pressure outside the storm. In all storms, however, the eye is the location of the storm's minimum barometric pressure: the area where the atmospheric pressure at sea level is the lowest.

At the center of the hurricane is the eye, a cloud-free area of sinking air and light winds that is usually from 10 to 65 kilometers in diameter. Bordering the eye of a mature hurricane is the eye wall, a ring of tall thunderstorms that produce heavy rains and very strong winds. The most destructive section of the storm is in the eye wall on the side where the wind blows in the same direction as the storm’s forward motion. The eye is a region of mostly calm weather at the center of strong tropical cyclones. The eye of a storm is a roughly circular area, typically 30–65 km (20–40 miles) in diameter. It is surrounded by the eyewall, a ring of towering thunderstorms where the most severe weather occurs. There is, however, very little wind and rain, especially near the center. This is in stark contrast to conditions in the eyewall, which contains the storm's strongest winds. Due to the mechanics of a tropical cyclone, the eye and the air directly above it are warmer than their surroundings. The eye that shows up in mature hurricanes represents the center of the storm. Counterintuitively to some, the eye represents an area of the hurricane where there is little to no precipitation, the sun or stars can be visible for a time, and the winds are light. Also within the eye is the lowest barometric pressure associated with the hurricane. The eye of a hurricane can range in size from about 5 miles (8 km) up to as wide as 120 miles (200 km) in diameter; however, a typical size is usually about 20-40 miles (30-60 km).  Within the eye wall, the wind speed reaches its maximum but within the eye, the winds become very light sometimes even calm. The surface pressure continues to drop through the eye wall and into the center of the eye, where the lowest pressure is found. Upon exiting the eye, the wind speed and pressure both increase rapidly. The wind speed again reaches a maximum in the opposite eye wall, and then quickly begins to decrease. Between 100 and 200 kilometers from the eye, the winds are fast enough to qualify as tropical storm force. The atmospheric pressure here will still be relatively high compared to the storm's center at about 990 to 1010 millibars.
