Barometric pressure decreases as a hurricane gets stronger. A Category 1 storm will have barometric pressure of at least 28.94. At the other end of the scale, a Category 5 storm will have air pressure of 27.17 or lower. Meteorologists also use a measurement called a millibar, which is faster for them to calculate, but gives measurements equivalent to barometer readings. These measure the intensity of a storm. Hurricane Wilma, a Category 5 storm which came near the end of the particularly active and destructive 2005 season, holds the current record (as of mid-2014) for intensity. When the storm was strongest, its low barometric pressure was 26.82, or 882 millibars. By contrast, there is a tie for 10th place on the list of most intense Atlantic hurricanes. The Cuba storm of 1924 and Hurricane Ivan (2004) each had a low barometric pressure of 26.88, or 910 millibars.
What else can I help you with?
What Weather instrument indicates a storm is coming?
In order to know that a storm is coming, you need to know the air pressure. Storms are normally associated with a Low Pressure System. A Barometer can be a tool you can use to predict an oncoming storm.
How can you use a barometer to detect changes in air pressure?
A barometer is used in 2 ways. First you keep it stationary. You record the pressure. If the pressure drops, it means, a storm is coming. Second, in a car or airplane when the barometer falls, it means you are getting higher. When the barometer drops, it means you are getting lower.
What instrument measures air pressure decreases during a storm?
Barometers measure air pressure.
When the barometer is dropping what is the air pressure doing?
increasing
If the barometer shows rapidly falling air pressure what kind of weather should be expected?
Rapidly falling air pressure on a barometer usually indicates an approaching low-pressure system or storm, suggesting that stormy weather, such as rain, strong winds, or even thunderstorms, may be on the way.
What Weather instrument indicates a storm is coming?
In order to know that a storm is coming, you need to know the air pressure. Storms are normally associated with a Low Pressure System. A Barometer can be a tool you can use to predict an oncoming storm.
Use barometer in a sentence?
Since the barometer read that the air pressure was high, the boy brought an umbrella outside.
How does a barometer instrumental in predicting storms?
A barometer measures air pressure, which can decrease before a storm due to the approaching low-pressure system. A rapid drop in air pressure indicates an impending storm. Monitoring the barometric pressure allows meteorologists to forecast and predict the onset of storms.
Do mercury barometer fal or rise when a storm is approaching?
it falls , due to low pressure ...

How does an aneroid barometer measure atmospheric pressure?
A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury.An aneroid barometer is a barometer which measures pressure without using fluids!An aneroid barometer is somewhat different and uses a sealed chamber upon which the fluctuating atmospheric pressure acts. Through mechanical means a pointer is moved on a calibrated scale.
How would you expect the reading on a barometer to change as a storm moves into your area?
Yes. You would expect the pressure to drop. A low pressure system consists of rising warm air that swirl around a center. Because the air is rising, it lowers the air pressure pressed on the ground. Because of this the pressure-sensing barometer will read that the air pressure is lower. Lower pressure means rain because the warm rising air makes clouds. Expect the pressure to drop as a storm is a low pressure system. Note that cyclones/hurricanes have even lower pressure.
Does a borometer reading raise before a storm?
Yes, a barometer reading typically drops before a storm, suggesting lower air pressure. This decrease in pressure usually indicates that a storm or unstable weather is approaching.
What instrument measures air pressure decreases during a storm?
Barometers measure air pressure.
What is sudden fall of a barometer reading indicate is?
A sudden fall in a barometer reading typically indicates an approaching low-pressure system or storm. This drop in pressure can be a sign of worsening weather conditions, such as rain, strong winds, or thunderstorms.
Can a barometer track the activity of storms at different altitudes?
Highly accurate barometers take atmospheric pressure readings for use in many scientific applications. Changes in atmospheric pressures signal changes in weather, and pressure drops as altitude rises. So, adjusted to its altitude a barometer can track storms at different altitudes.
How the barometer is used?
A barometer is advice used to atmospheric pressure. They are commonly contain water, air, or mercury. The medium used raises and falls in a tube with a reservoir at the base. The pressure from the outside air pushes on the medium in the exposed reservoir. This push is what causes the medium raise or fall. The measure of the barometer can indicate local weather patterns. High pressure indicates fair weather, while low pressure indicates a storm.
