'''Hypercane Katia''' (also referred to as '''Superstorm Katia''' or '''The Storm of the Century II''') was the first [[hypercane]] ever recorded in history. It was also the deadliest, costliest and most intense [[tropical cyclone]] ever recorded, and also produced the highest winds recorded on the surface of the [[wikipedia:Earth|Earth]] measured by Hurricane Hunters:
549
miles per hour (
884
km/h). The eleventh named storm, seventh hurricane and sixth major hurricane of the hyperactive and record-breaking [[2041 Atlantic hurricane season (Mario's version)|2041 Atlantic hurricane season]], Katia formed out of a vigorous tropical wave that moved off the coast of Africa on August 7, while continuing westward across the Atlantic. Development did not occur until just before the wave reached the Lesser Antilles, where organization quickly took over and developed into a tropical storm while situated to the east of the Antilles late on August 15. The storm gradually strengthened until entering the western Caribbean Sea on August 20, where unprecedented explosive deepening took place, and Katia went from a tropical storm to a Category 6 in 24 hours – a record pace. It eventually attained its peak intensity in the middle of the Gulf of Mexico on August 29 before striking near New Orleans, Louisiana as a slightly weaker storm on September 1. It rapidly weakened while inland and eventually dissipated on September 9.

'''Hypercane Katia''' (also referred to as '''Superstorm Katia''' or '''The Storm of the Century II''') was the first [[hypercane]] ever recorded in history. It was also the deadliest, costliest and most intense [[tropical cyclone]] ever recorded, and also produced the highest winds recorded on the surface of the [[wikipedia:Earth|Earth]] measured by Hurricane Hunters:
602
miles per hour (
969
km/h). The eleventh named storm, seventh hurricane and sixth major hurricane of the hyperactive and record-breaking [[2041 Atlantic hurricane season (Mario's version)|2041 Atlantic hurricane season]], Katia formed out of a vigorous tropical wave that moved off the coast of Africa on August 7, while continuing westward across the Atlantic.

It eventually attained its peak intensity in the middle of the Gulf of Mexico on August 29 before striking near New Orleans, Louisiana as a slightly weaker storm on September 1. It rapidly weakened while inland and eventually dissipated on September 9.
Up to $1 trillion in damages were attributed to the storm, making Katia the costliest tropical cyclone on record. It also killed more then 100,000 people, making it the deadliest such storm on record, surpassing that of the [[Wikipedia:Great Hurricane of 1780|Great Hurricane of 1780]], nearly 260 years earlier. The [[Wikipedia:National Hurricane Center|National Hurricane Center]] (NHC) described the cyclone as "a warning sign that global warming is occurring and that we need to stop it before more storms of this magnitude strike causing more catastrophic damages and loss of life".

On August 7, a vigorous tropical wave moved off the west coast of Africa, with a decent amount of thunderstorm activity as it progressed westward at a steady pace of around 9–10 mph (14–16 km/h). The wave was not anticipated to develop until reaching the Caribbean or the Bahamas, due to moderate to high wind shear. By August 10, the wave was designated as a potential area for development (named ''Invest 91L'') by the National Hurricane Center (NHC) as it approached the Lesser Antilles. Moving west to west-northwestward, the disturbance then began to develop rapidly, and on late on August 15, a Hurricane Hunter aircraft confirmed the presence of a closed circulation center about 500 miles (800 km) to the east of the Lesser Antilles. This prompted the NHC to upgrade the disturbance to a tropical storm at 18:00 UTC on August
13
, and it was assigned the name ''Katia''.

The newly-formed tropical storm continued to gradually move westward towards the western Caribbean Sea while strengthening early on August 20, as an anticyclone began to build above it. As it reached the western Caribbean Sea, wind shear virtually vanished, extreme sea surface temperatures of around 42 °C (108 °F) and historic ocean heat content indexes prompted historic explosive intensification, and Katia went from a 70 mph (110 km/h) tropical storm on August 20 to a 220 mph (350 km/h) Category 6 hurricane on August 21. Its pressure also dropped nearly 150 millibars, going from 992 millibars (29.3 inHg) to 848 millibars (25.0 inHg) in the course of a day. The anticyclone over Katia continued to strengthen, prompting an outflow never before seen in any tropical cyclone – Katia was producing up to 90 knots of wind shear from its outflow, enough to destroy any tropical storm that got too close, which was the quick demise of [[Tropical Storm Jose (2041)|Tropical Storm Jose]]. Continuing to take advantage of the extremely favorable conditions, the hurricane continued to explosively deepen on a historic scale throughout the next few days as it progressed slowly to the west, and after gradually turning to the northwest, Katia made landfall on the western tip of Cuba as a Category 7 hurricane with winds of 445 mph (716 km/h) on August 26. Immediately after, the hurricane entered the Gulf of Mexico. A second period of explosive deepening took place as it encountered sea surface temperatures of up to 49 °C (120 °F), and Katia eventually reached its peak intensity on the afternoon of August 27 as a hypercane with maximum winds of
520
mph (
835
km/h) and a minimum pressure of 617 millibars (18.
22inHg
), making it the strongest tropical cyclone ever recorded on the planet. Shortly after attaining its peak intensity, a dropsonde from a Hurricane Hunters aircraft was dropped into the eyewall of the storm, and measured a sea-level sustained wind gust of
549
mph (
884
km/h), which was later confirmed to not be contaminated by heavy rainfall. This was officially the highest surface winds ever recorded on the Earth.

Continuing to move northwest, Katia maintained its peak strength for another 24 hours, before undergoing an eyewall replacement cycle, and weakening slightly to
510
mph (
800
km/h) on August 28. The final destination for landfall was predicted to be near New Orleans, Louisiana, with catastrophic or likely total damage predicted. Before landfall, an elongated trough associated with the remnants of Hurricane
Boris
from the Eastern Pacific began to move eastward through the United States, and Katia began to interact with this trough as it neared landfall. On September 1, at 12:30 p.m CDT, Katia made landfall about 20 miles (32 km) south of New Orleans as a hypercane with winds of
500
mph (
800
km/h) and a pressure of 658 millibars (19.4 inHg), making it the strongest landfalling tropical cyclone ever recorded. The eye of the cyclone passed directly over New Orleans, with reports of a "partly cloudy" sky in the eye. New Orleans was also hit with the worst part of the eyewall, which the National Hurricane Center described as "basically an EF5+ tornado that was 50 miles wide". Now inland, Katia began to steadily weaken as it made its second landfall about 105 miles (169 km) west of Gulfport, Mississippi as a Category 7 with winds of 315 mph (507 km/h), its winds having finally dropped below hypercane-force. The hurricane then underwent dramatic weakening as it began to accelerate to the northeast, with Katia weakening to a tropical storm by late on September 3. On September 4, Katia completed its transition into an extratropical cyclone while situated over Tennessee as a 35 mph (56 km/h) storm. Katia was last noted on September 9 off the coast of Boston, Massachusetts before dissipating.
