The 1990 Azkali cyclone was a devestating off-season Volic Gulf cyclone that struck Azkali and Sunteria on 12 Agotzo 1990 (27 Snoiguia 3116). It remains the cyclone with the fastest recorded wind speed and lowest barometic pressure on record. It was the deadliest tropical cyclone in recorded history, and greatly exacerbated the at the time ongoing Azkali societal collapse, resulting in one of the most devestating humanitarian disasters in the history of the world. It caused approximately 400,000 deaths, and possibly as much as 750,000. These casualties were almost solely in Azkali, and caused damages there estimated at $440 billion dollars. The 1990 Azkali cyclone was the first cyclonic storm of the 1990 Volic cyclone season.
The 1990 Azkali cyclone caused apocalyptic flooding across Azkali and Sunteria, rendering it visible from space, breaking many local and national meteorological records. As it made landfall, it caused a 12.2 meter (40 foot) storm surge that completely destroyed all coastal communities in its wake.
Meteorological history
On the 24th of Uni, 1990 (Sunterian time), a tropical wave moved from northern Tyrosia northeast into the Volic Gulf. It was monitored by the Ari Island Volunteer Meteorological Center for several days, but was discontinued from being monitored as it failed to produce atmospheric convection. Over the coming days thereafter, however, the tropical wave slowly organized, and on the 3rd of Agotzo, the wave organized into Tropical Depression 1. Despite the wave's organizing, the AIVMC failed to further monitor the storm until the 10th of Agotzo.
Over the next three days, the tropical depression moved northeast, entering into a zone with anomalously warm water temperatures and little wind shear. By the 6th of Agotzo, the depression had organized further, and began to be monitored by the (Sunterian Meteorological agency). The same day, the (SMA) categorized the depression as a Severe Tropical Storm - however, it was not given a name, being several months before the start of the cyclone season. At noon on the 7th of Agotzo, hurricane hunters reported the intensification of the cyclone from a Severe Tropical Storm to a Cyclone, with sustained winds of 95 miles per hour, with recorded gusts of up to 110 miles per hour. A mid-level ridge to the north of the cyclone steered it west along an elongated arcing path, into waters with cooler water temperatures. The cyclone stalled and weakened slightly into a Severe Tropical Storm starting at around 10:00 PM on the 7th.
Around this time, Western Azkali and Kalilonde were experiencing significant amounts of rainfall, on average approximately 3 or 4 inches so.
The next day, the cyclone started again west, into an environment with ocean temperatures exceptionally conductive to explosive intensification. By 4:00 AM on the 8th, it had re-intensified into a cyclone, but was prevented from strengthening that day due to significant wind shear in the cyclone's path. Wind shear gradually dissipated over the day, and by 11:00 PM on the 8th, the cyclone weakened slightly once more to a severe tropical storm, before explosively intensifying into a Super Cyclone, starting at 9:00 AM on the 9th of Agotzo. Hurricane hunters around this time reported the increase of the cyclone's 10 minute sustained wind speed from approximately 85 miles an hour to 200 miles an hour in six hours, an intensification of 115 miles an hour within 6 hours, or approximately an increase of 20 an hour.
In the days before landfall, the cyclone intensified to its record breaking maximum wind speed, an estimated 230 miles an hour. In the hours before it made landfall, it slightly weakened, leaving it's landfall wind speed at a staggering 220 miles an hour.
The cyclone made landfall at 11:40 AM on the 12th of Agotzo, in the village of Hengatzeisu. As it made landfall onto the southern Azkali coast, the cyclone stalled for several days, causing catastrophic rainfall; the maximum recorded being in the village of Ngetetz, a suburb of Retzal, with a record breaking 212 inches of rainfall over thirty-six hours, a world record. The cyclone slowly weakened from a super cyclone to a cyclone, still sustaining winds of over 100 miles an hour until the 16th of Agotzo. On the 17th, the cyclone began to weaken further and headed northwest, reentering the Volic Gulf on the 18th. It curved northeast, quickly intensifying into a Super Cyclone with winds of 160 miles an hour, before making a second landfall at Ichatzoaka. The cyclone weakened into a severe tropical storm several hours before landfall, and curved northwest, heading into Kalilonde. The cyclone continued to drop catastrophic levels of rainfall, and the cyclone even re-intensified into a proper cyclone as it continued into Kalilonde, perpetuated by the massive amount of rainfall that had occured in western Azkali and Kalilonde days before; a textbook example of the Brown ocean effect.
However, starting on the 19th, as it entered into dry land, the cyclone quickly weakened, and by 9:00 AM on the 20th, it transitioned into an extratropical system. The remnants continued to move northwest it was absorbed another extratropical system
Preparations
There was no preparation for the cyclone as it struck Azkali. The widespread lack of any utilities in the area made it impossible for any news of the cyclone's existence to reach the area from the outside world. As described by one anonymous survivor, "we were struck in the back [of] the head while on the ground weeping".[1] The only prior warning that reached the zone where the cyclone made landfall occurred late in the afternoon on the 11th of Agotzo from the AIVMC, which published a two sentence bulletin severely underestimating the date of landfall and wind speed of the cyclone: "A cyclone has been spotted in the Volic Gulf, which will make landfall approximately late in the evening of the 13th of Agotzo in the South of Azkali. The cyclone's wind speed is estimated at 100 miles an hour, so people there are recommended to prepare several days of supplies in anticipation of this cyclone." By this time, the cyclone was at its maximum estimated wind speed, with ten-minute sustained winds of approximately 230 miles an hour.
