Lower pressure generally means higher wind speed. The relationship is approximately 1050-mm=Kt where mm is the pressure in millibars of Mercury and Kt is the wind speed in knots. 1 knot = 1.15 mph.
At extremely low pressures, the relationship can become a bit skewed due to eyewall replacement cycles but the formula is a good rule of thumb.
Examples: Katrina (2005) Min pressure 902mm, max wind 150kt. Hugo (1989) min pressure 918mm, max wind 140kt.

What does the increase or decrease of millibars have to do with hurricanes?
The decrease in millibars indicates a drop in atmospheric pressure, which correlates with the increasing intensity of a hurricane. A lower pressure system allows air to rise and fuels the storm's development and strength. Conversely, an increase in millibars signifies a rise in atmospheric pressure, which can weaken the hurricane.
What causes the winds to rush toward hurricane areas?
Winds rush towards hurricane areas due to the pressure difference between the high-pressure system surrounding the hurricane and the lower pressure within the storm. Air moves from high pressure to low pressure, creating strong winds that spiral towards the center of the hurricane.
Why is a hurricane stronger with less pressuere?
Hurricanes feed on warm, moist air that they pull in. The lower the pressure, the more air they can pull in. Also, the lower pressure creates a larger force on the air, causing it to go faster. As more warm moist air gets pulled in the convection intensifies, causing the pressure to drop even further.
The center of a hurricane is characterized by very low what?
A hurricane has very low barometric pressure.
Why does low pressure make a hurricane stronger?
In simple terms, wind is driven by pressure differences. A larger pressure difference over a given distance will produce a larger force on the air and thus create faster winds. As with most storms, air pressure in a hurricane is lower than that of its surroundings. Lowering the pressure in a hurricane creates a larger pressure difference and thus stronger winds.
What type of air pressure is associated with a hurricane?
A hurricane is associated with low air pressure.
What does the increase or decrease of millibars have to do with hurricanes?
The decrease in millibars indicates a drop in atmospheric pressure, which correlates with the increasing intensity of a hurricane. A lower pressure system allows air to rise and fuels the storm's development and strength. Conversely, an increase in millibars signifies a rise in atmospheric pressure, which can weaken the hurricane.
How does the low pressure associtated with a hurricane help them grow big and powerful?
Air in the atmosphere tends to move toward low-pressure regions, which would increase the winds surrounding a hurricane. Air in the atmosphere moves from areas of high pressure to areas of low pressure. Air rushing toward a hurricane causes the hurricane to grow in size and strength.
Is there low air pressure or high air pressure in the eye of a hurricane?
There is low air pressure in the eye of a hurricane. This low pressure causes the surrounding air to spiral inwards towards the center of the storm, producing the strong winds characteristic of a hurricane.
Do people really die from lack of air from a hurricane?
No, there is plenty of air (and air pressure) in a hurricane, and plenty of other ways to die in a hurricane.
Does air pressure increase as you go towards the center of a hurricane?
No. Air pressure decreases.
Where is the lowest air pressure typically found within a hurricane?
The lowest air pressure in a hurricane is typically found at the center of the storm, known as the eye.
Does the air pressure change during the formation of a hurricane and why is that important?
yes the air pressure changes
Does air pressure increase or decrease towards the center of the hurricane?
Air pressure decreases towards the center of a hurricane, reaching its lowest point at the eye of the storm. This decrease in pressure is a key factor in the strong winds and intense storm surge associated with hurricanes.
Would the air pressure in the center of a hurricane be lower or higher than standard air pressure?
higher
What causes the winds to rush toward hurricane areas?
Winds rush towards hurricane areas due to the pressure difference between the high-pressure system surrounding the hurricane and the lower pressure within the storm. Air moves from high pressure to low pressure, creating strong winds that spiral towards the center of the hurricane.
