Hurricane Nate comes ashore in Louisiana & Mississippi as 4th US hurricane of 2017

Written by on October 8, 2017 in Summer 2017, Tropical, United States of America with 0 Comments

Hurricane Nate made it’s first landfall near the mouth of the Mississippi River, LA at 7pm ET Saturday night and later made a 2nd landfall near Biloxi, MS at 12.30am Sunday. Both landfalls were Category 1 with 85 mph winds. Nate weakened slightly prior to landfall due to land interaction, dry air and cooler waters from it’s peak intensity of 90 mph out over the open Gulf of Mexico.

Nate’s record forward speed of nearly 30 mph may also have aided some weakening prior to landfall as well as providing it’s raged appearance.

VERY significant storm surge in Biloxi, MS.

4th US hurricane of 2017

Following a record 3 Category 4 US landfalls, Nate becomes the 4th US landfalling hurricane of the 2017 season. The last time this occurred with during the epic 2005 season.

That 2005 season featured five U.S. landfalling hurricanes: Cindy, Dennis, Katrina, Rita and Wilma.

The previous season, 2004, also featured five U.S. landfalls, including the infamous Florida four of Charley, Frances, Ivan and Jeanne.

According to NOAA’s Hurricane Research Division, only 13 other years featured at least four U.S. hurricane landfalls in the same season:

  • 6 landfalls: 1985, 1886
  • 5 landfalls: 2005, 2004, 1933, 1916, 1893
  • 4 landfalls: 1964, 1909, 1906, 1888, 1869, 1852

As you can see above, 2017 was only the third season in the last 50-plus years to have this happen.

The Three Category 4 U.S. Landfalls of 2017

Hurricane Maria made landfall with winds of 155 mph on September 20 in Puerto Rico.

In the weeks before Maria, hurricanes Harvey and Irma made landfall at Category 4 intensity with 130 mph winds on August 25 in Rockport, Texas, and September 10 in the Florida Keys, respectively.

Winds for a Category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale range from 130 mph to 156 mph. Winds of that strength are capable of causing catastrophic damage. The scale does not factor other major hazards from hurricanes such as storm surge and flooding rainfall.

The landfall of Harvey and Irma at Category 4 strength was already a historic event, marking the first time two Atlantic hurricanes struck the U.S. in the same year. With Puerto Rico taking a direct hit from Maria, the U.S. has now endured landfalls from three Category 4 hurricanes.

Category 4 or stronger Atlantic hurricane landfalls in the Lower 48 are a rare occurrence, with only 27 documented since 1851, including Harvey and Irma. Three of those 27 landfalls were Category 5 hurricanes.

Puerto Rico has experienced four Category 4 or stronger landfalls, including Maria, which was the strongest landfall there since 1928.

As mentioned earlier, the names Harvey, Irma and Maria could be retired from being used in future hurricane seasons.

Atlantic hurricane and tropical storm name lists repeat every six years unless one is so destructive and/or deadly that the World Meteorological Organization votes to retire that name from future lists.

The last time three Atlantic tropical storm or hurricane names were retired in a single season was 2008, when Gustav, Ike and Paloma were eliminated from future use.

Only 10 other years since 1954 have had three or more Atlantic tropical storm or hurricane names retired, according to the National Hurricane Center. 2017 could be the 11th year to have that many retirees after the WMO meets next year to make their decision on what names will be removed from use.
