Question: Hurricane Irma and Hurricane Wilma we're which category of hurricane at their strongest?
Context: The effects of Hurricane Wilma in The Bahamas were generally unexpected and primarily concentrated on the western portion of Grand Bahama.  Hurricane Wilma developed on October 15, 2005 in the Caribbean Sea, and after initially organizing slowly it explosively deepened to reach peak winds of 185 mph (295 km/h) and a record-low pressure of 882 mbar (hPa).  It weakened and struck eastern Mexico as a Category 4 hurricane on the Saffir-Simpson scale, and accelerated northeastward to make landfall on southwestern Florida on October 24.  After crossing the state, Wilma briefly restrengthened in the open Atlantic Ocean, moving north of The Bahamas before weakening and later becoming an extratropical cyclone. The 1924 Cuba hurricane is the earliest officially classified Category 5 Atlantic hurricane on the Saffir–Simpson scale, and one of two hurricanes to make landfall on Cuba at Category 5 intensity, the other being Hurricane Irma in 2017.  It formed on October 14 in the western Caribbean, slowly organizing as it tracked northwestward.  By October 16, it attained hurricane status to the east of the Yucatán Peninsula, and subsequently executed a small counterclockwise loop.  On October 18, the hurricane began undergoing rapid deepening, and the next day it reached an estimated peak intensity of 165 mph (270 km/h).  Shortly thereafter, it struck extreme western Cuba at peak intensity, becoming the strongest hurricane on record to hit the country.  Later the hurricane weakened greatly, striking southwestern Florida with winds of 90 mph (150 km/h) in a sparsely populated region.  While crossing the state it weakened to tropical storm status, and after accelerating east-northeastward, it was absorbed by a cold front on October 23 south of Bermuda. Hurricane Felix was the southernmost landfalling Category 5 hurricane in the Atlantic; surpassing Hurricane Edith of 1971.  It was also the most recent Atlantic hurricane to make landfall as a Category 5 until Hurricane Irma in 2017.  It was the sixth named storm, second hurricane, and second Category 5 hurricane of the 2007 Atlantic hurricane season.  Felix formed from a tropical wave on August 31, passing through the southern Windward Islands on September 1 before strengthening to attain hurricane status.  A day later it rapidly strengthened into a major hurricane, and early on September 3 it was upgraded to Category 5 status; by 2100 UTC, the hurricane was downgraded to Category 4 status, but was upgraded to a Category 5 hurricane for the second and final time by the morning of September 4. Hurricane Maria was the tenth-most intense Atlantic hurricane on record, the worst natural disaster in Dominica in its recorded history, and the strongest to make landfall in Puerto Rico since 1928.  The thirteenth named storm, seventh hurricane, fourth major hurricane, and the second Category 5 hurricane of the unusually active 2017 Atlantic hurricane season, Maria caused catastrophic damage during its journey across the Northeastern Caribbean as the second more intense landfall and the costliest hurricane ever to hit the region.  It was the third major hurricane in a row to threaten the Leeward Islands with a direct strike or major impacts within two weeks, after Hurricane Irma caused catastrophic damage there and Jose, then a Category 4 hurricane, passed dangerously close just days after. The effects of Hurricane Wilma in Florida were catastrophic, becoming the second costliest Florida hurricane ever recorded.  Hurricane Wilma was first evident near Jamaica and was classified as a hurricane on October 18.  Initially, orange future prices soared on October 19, 2005.  As the system drew closer, schools and government offices closed on October 21.  Professional and college sports games were rescheduled during Wilma's advance towards Florida.  Evacuations were ordered for southwestern Florida and the Keys.  As the storm made landfall, a storm surge swept into coastal sections of southern Florida and high winds led to significant damage near and along Wilma's path, particularly to the power grid.  Some locations were without power for 2–3 weeks after the storm.  Wilma spawned ten tornadoes in Florida.  At least 35 Wilma-related deaths were reported in the United States, all in Florida.  Wilma was also blamed for at least 26 indirect deaths.  Damage in Florida totaled $20.6 billion (2005 USD; $22.7 billion 2008 USD). Hurricane Wilma was the most intense tropical cyclone ever recorded in the Atlantic basin, as well as the most intense recorded in the western hemisphere until Hurricane Patricia in 2015.  Part of the record-breaking 2005 Atlantic hurricane season, which included three of the top ten most intense Atlantic hurricanes ever (along with #4 Rita and #7 Katrina), Wilma was the twenty-second storm, thirteenth hurricane, sixth major hurricane, fourth Category 5 hurricane, and second-most destructive hurricane of the 2005 season.  A tropical depression formed in the Caribbean Sea near Jamaica on October 15, headed westward, and two days later intensified into a tropical storm which turned abruptly southward and was named "Wilma".  Wilma continued to strengthen, and eventually became a hurricane on October 18.  Shortly thereafter, explosive intensification occurred, and in only 24 hours, Wilma became a Category 5 hurricane with wind speeds of 185 mph . Hurricane Irma was an extremely powerful and catastrophic Cape Verde-type hurricane, the strongest observed in the Atlantic since Wilma in 2005 in terms of maximum sustained winds.  It was the first Category 5 hurricane to strike the Leeward Islands on record, followed by Hurricane Maria only two weeks later.  It was also the most intense Atlantic hurricane to strike the United States since Katrina in 2005, and the first major hurricane to make landfall in Florida since Wilma in 2005.  The ninth named storm, fourth hurricane, and second major hurricane of the 2017 Atlantic hurricane season, Irma caused widespread and catastrophic damage throughout its long lifetime, particularly in parts of the northeastern Caribbean and the Florida Keys. Hurricane Floyd was a very powerful Cape Verde-type hurricane which struck the east coast of the United States.  It was the sixth named storm, fourth hurricane, and third major hurricane in the 1999 Atlantic hurricane season.  Floyd triggered the fourth largest evacuation in US history (behind Hurricane Irma, Hurricane Gustav, and Hurricane Rita) when 2.6 million coastal residents of five states were ordered from their homes as it approached.  The Cape Verde-type hurricane formed off the coast of Africa and lasted from September 7 to September 19, peaking in strength as a very strong Category 4 hurricane—just 2 mph short of the highest possible rating on the Saffir–Simpson Hurricane Scale.  It was among the largest Atlantic hurricanes of its strength ever recorded. Hurricane Mitch was the second deadliest Atlantic hurricane on record.  The storm was the thirteenth tropical storm, ninth hurricane, and third major hurricane of the 1998 hurricane season.  Along with Hurricane Georges, Mitch was the most notable hurricane in the season.  At the time, Hurricane Mitch was the strongest Atlantic hurricane observed in the month of October, though it has since been surpassed by Hurricane Wilma of the 2005 season.  The hurricane matched the fourth most intense Atlantic hurricane on record (it has since dropped to seventh). Hurricane Dean was the strongest tropical cyclone of the 2007 Atlantic hurricane season.  It was the most intense North Atlantic hurricane since Hurricane Wilma of 2005, tying for eighth overall.  Additionally, it made the third most intense Atlantic hurricane landfall.  A Cape Verde-type hurricane that formed on August 13, 2007, Dean took a west-northwest path from the eastern Atlantic Ocean through the Saint Lucia Channel and into the Caribbean.  It strengthened into a major hurricane, reaching Category 5 status on the Saffir–Simpson hurricane wind scale before passing just south of Jamaica on August 20.  The storm made landfall on the Yucatán Peninsula on August 21 as a powerful Category 5 storm.  It crossed the peninsula and emerged into the Bay of Campeche weakened, but still a hurricane.  It strengthened briefly before making a second landfall near Tecolutla in the Mexican state of Veracruz on August 22.  Dean drifted to the northwest, weakening into a remnant low which dissipated uneventfully over the southwestern United States.
