What is the lowest pressure of a tropical cyclone?
Typically, atmospheric pressure at the surface of Earth is about 1,000 millibars. At the centre of a tropical cyclone, however, it is typically around 960 millibars, and in a very intense “super typhoon” of the western Pacific it may be as low as 880 millibars.
What is the low pressure Centre of a cyclone called?
the eye
A cyclone’s center (often known in a mature tropical cyclone as the eye), is the area of lowest atmospheric pressure in the region.

What was Hurricane Katrina’s pressure?
902 mb
Katrina also reached a minimum central pressure of 902 mb at its peak, ranking 4th lowest on record for all Atlantic basin hurricanes. The vicious storm killed over 1,800 people, disrupted thousands of lives over tens of thousands of square miles, and damaged or destroyed 275,000 homes.
Where was Cyclone Yasi in Australia?
north Queensland coast
Severe Tropical Cyclone Yasi slammed into the north Queensland coast near Mission Beach in the early hours of 3 February 2011. As a category 5 storm at landfall, it was one of the most powerful tropical cyclones to hit Queensland since records commenced.
What is a cat 2 cyclone?
Category two (tropical cyclone) Significant damage to signs, trees and caravans. Heavy damage to some crops. A category two cyclone’s strongest winds are DESTRUCTIVE winds with typical gusts over open flat land of 125-164kph. These winds correspond to Beaufort 10 and 11 (storm and violent storm).
How was Cyclone Yasi formed?
Severe Tropical Cyclone Yasi began developing as a tropical low northwest of Fiji on 29th January and started tracking on a general westward track. During this time, Yasi started to take a more west-southwestward movement and began to accelerate towards the tropical Queensland coast.
What was the lowest pressure recorded in Yasi?
Timeseries of atmospheric pressure recorded from the Bureau of Meteorology’s tsunami DART buoy as Severe Tropical Cyclone Yasi passed over it. The lowest pressure reading is 941hPa.
How did Cyclone Yasi weaken to a tropical low?
Because it was such a large, strong storm, Yasi maintained considerable intensity as it tracked inland into the state’s north-west, finally weakening to a tropical low near Mount Isa more than 20 hours after it crossed the coast.
Where did Tropical Cyclone Yasi hit in Queensland?
Being such a strong and large system, Yasi maintained a strong core with damaging winds and heavy rain, tracking westwards across northern Queensland and finally weakened to a tropical low near Mount Isa around 10pm on 3rd February. Yasi is one of the most powerful cyclones to have affected Queensland since records commenced.
When did Cyclone Yasi hit Tuvalu in 2011?
Tropical Disturbance 09F was first identified on 26 January 2011 by the Fiji Meteorological Service (FMS), while it was 330 km (205 mi) south-southwest of Tuvalu. Over a region of high sea surface temperatures and low to moderate wind shear, it was expected to intensify gradually as it moved southwest.
