what does the minimum pressure in a hurricane mean
Eye (cyclone) In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. 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 pressureâ€”where the atmospheric pressure at sea level is the lowest.[1][2]
1921 Tampa Bay hurricane The Tampa Bay hurricane of 1921 (also known as the 1921 Tarpon Springs hurricane) is the most recent major hurricane to strike the Tampa Bay Area. The eleventh tropical cyclone, sixth tropical storm, and fifth hurricane of the season, the storm developed from a trough in the southwestern Caribbean Sea on October 20. Initially a tropical storm, the system moved northwestward and intensified into a hurricane on October 22 and a major hurricane by October 23. Later that day, the cyclone peaked as a Category 4 on the modern day Saffir–Simpson scale with maximum sustained winds of 140 mph (220 km/h). After entering the Gulf of Mexico, the hurricane gradually curved northeastward and weakened to a Category 3 before making landfall near Tarpon Springs, Florida, late on October 25, becoming the first major hurricane to hit the area since a hurricane in 1848. The storm quickly weakened to a Category 1 hurricane while crossing Central Florida, before reaching the Atlantic Ocean early on the following day. Thereafter, system moved east-southeastward and remained fairly steady in intensity before weakening to a tropical storm late on October 29. The storm was then absorbed by a larger extratropical cyclone early the next day, with the remnants of the hurricane soon becoming indistinguishable.
