Typhoon Michael has actually made landfall near Mexico Beach, Florida.

The storm got steam as it sped throughout the Gulf of Mexico towards the Florida Panhandle When its eye struck Florida’s Gulf Coast on Wednesday afternoon, the storm had actually sustained winds of 155 miles per hour, according to the National Typhoon Center, putting it simply shy of a Classification 5 cyclone

Michael’s minimum main pressure– a crucial step of cyclone strength– was determined at 919 millibars when it made landfall. That makes Michael the 3rd greatest cyclone to ever strike the United States, and the greatest in 50 years.

Lower main pressure shows a more powerful storm. Michael’s measurement shows that it’s more extreme than Typhoon Andrew, which struck Florida in 1992 with a pressure of 922 mb. Katrina, which ravaged New Orleans in 2005, had a pressure of 920 mb.

Main pressure is the step of just how much the environment in the middle of a storm weighs. Regular atmospheric pressure is about 1010 mb; when main pressure is considerably lower than that, things end up being more rough, with more air motion and wind kicking up.

Main pressure is really a much better step of the damage that a cyclone will trigger than wind speed, according to a research study released in the journal Nature Communications in 2017, though wind is the basis for cyclone classifications.

However Michael is a beast storm by wind speed also. The continual 155 miles per hour winds make it not far from a Classification 5 storm– the cut off in between Classification 4 and 5 is 156 miles per hour. There’s just been one storm with greater continual wind speeds this far north in the Gulf of Mexico prior to: Typhoon Camille in1969
