Hurricane Michael Third Most Powerful to Hit U.S

2020-02-19 15:14:35    阅读:298702

Hurricane Michael made landfall in Mexico Beach, Fla. on Wednesday with sustained winds of 155 miles per hour. That put it just shy of a Category 5 hurricane, which would require wind speeds of 157 mph, but Michael is nevertheless one of the strongest storms to ever strike the American mainland. Michael was continuing to intensify even

as it made landfall Wednesday, an unusual phenomenon that surprised some experts. Hurricanes typically lose power as they move inland away from the warm waters that fuel them and encounter less favorable wind conditions. I think that if people are comparing storms, what was really fascinating was that it was still intensifying when it was making landfall, which is similar to Hurricane Camille also intensifying as it moved inland, says AccuWeather Senior Mete999966WWWCom港澳超级 orologist Dan Kottlowski. Other storms like Hurricane Opal in 1995 actually went from a Category 4 to 3, just like most storms that make landfall on the Gulf Coast tend to weaken. Related Stories

U.S.   Florida Weather Alert Warns of 'Falling Iguanas' There are several ways to measure a hurricanes strength. The most recog

nizable measurement, the Saffir-Simpson Hurricane Wind Scale, rates hurricanes from 1-5 based on their sustained wind speeds. But hurricanes can also be measured by their barometric pressure: generally speaking, the lower the pressure, the more intense the storm. And so f

ar, Hurricane Michaels pressure ranks as the third-lowest for any hurricane to strike the U.S. mainland, at 919 millibars. The only storms with lower pressure were Hurricane Camille in 1969, and the unnamed Labor Day hurricane of 1935. But Kottlowski noted that meteorologists are still analyzing Hurricane Michael, and its possible that it will be retroactively upgraded to Category 5 status based on wind speeds. Thats what happened

with Hurricane Andrew [the National Hurricane Center] looked at the pressure and reanalyzed and upgraded it to a Category 5 storm. It was very close. I think its possible that it will happen with Michael. It was only two miles per hour slower than a Category 5. Theyll do a thorough reanalysis of the data but itll take two to three months at least until the final report.  Regardless of Hurricane Michaels ultimate c

lassification, those in the path of the storm are facing life-threatening winds, storm surge and other dangerous conditions. The NHC said Michael could cause a storm surge of up to 14 feet, for instance. Storm surge will be the most damaging aspect of the storm, says Kottlowski. A lot of places on video showed houses under water. Were seeing up to nine feet of inundation in parts of Apalachicola, Florida, and that wasnt even where Michael made landfall.
