Path

The tornado formed northwest of Killeen, TX, or north of Copperas Cove as part of a supercell thunderstorm that moved southeast across Texas, extending from west central Texas to deep south Texas. As it started. It moved south at around 40 mph and tore through Killeen and Fort Hood, continuing south, accelerating to 60 mph as it reached the community of Florence.

It began to paralell Interstate 35, moving southwest, and tracking through many densely populated areas. As it approached Georgetown, a tornado warning was issued by the National Weather Service, and as it showed no signs of weakening, a tornado emergency was declared for Austin and surrounding areas. At this point, the tornado already was 1.5 miles wide in diameter and has caused significant damage to the areas around Georgetown and Round Rock. The twister moved straight across the Texas capital city, completely sweeping buildings from their foundations, scowering roads and destroying all government facilities, including the Texas State Capitol. As it left Austin behind, it accelerated to almost 70 mph, while tearing over San Marcos with windspeeds in excess of 322 mph, only to become larger and stronger.

At the same time, a few miles south, in New Braunfels, another tornado has formed in the area, moving east, then south, and then making a 180 degree turn, moving north at 40 mph. The megatornado that struck Austin and the tornado in New Braunfels were now on a direct collision course, and eventually fused near the community of Hunter, just off of I-35. With this, the twister has now gained even more width and strenght, and practically flew over New Braunfels, entirely levelling the city. It now had San Antonio as its next target.

As it approached Randolph AFB, it has reached its maximum confirmed width of 3.4 miles and hitting windspeeds near 370 mph, with a ground speed registered at about 70 mph, still moving southwest. It tore right through the heart of San Antonio, completely and utterly obliterating absolutely anything and everything in its path. After the impact on San Antonio, the tornado steadily weakened as the supercell moved southeast at a rapid rate, and after almost 3 hours, it finally dissipated near the community of D'Hanis, 50 miles west of San Antonio.

Aftermath

The tornado has caused at least 7000 deaths, hundreds of thousands of injuries, and countless people are missing, probably to never be found.

Damages are estimated to be at around 500 billion USD.

Killeen has sustained severe damage with this storm, homes being torn apart with only single walls standing and massive piles of debris blocking roads and any access ways.

New Braunfels, San Marcos, and Austin as well as the surrounding areas have sustained severe to devastating damage. Downtown Austin is unrecognizable. The Texas State Capitol as well as the state ministries surrounding it were swept clean off of their foundations. Road scowering occured through the downtown area as well as most suburbs of Austin. Popped gas lines caused explosions in Round Rock and Pflugerville resulting in additional deaths.

San Antonio was impacted the worst of all. The city has been reported to be completely wiped off the face of the earth, it will most likely take decades for these cities to return, if at all. Well built homes and businesses were entirely levelled, ground scowering occured up to 7 feet deep, some neighborhoods were swept clean with no debris left, as if this area was under construction or as if it was never built in the first place. A large trail of dirt can be seen from a height of 30000 feet, where the tornado tracked through the downtown area.

What once was the 3rd biggest city in Texas and the 7th biggest population center in the United States is no more.

Interstate 35 between Austin and San Antonio has been scowered so heavily that it is impassable. Entire chunks of pavement were ripped out of the ground leaving a dirt trail behind. Traffic jams up to 50 miles in length have formed on detour routes in rural areas. Air travel is the only way to assist those in need fast.

The Texas government has declared a state of emergency for the upcoming 3 months, and furthermore, abandoned Austin and declared Midland the new Texas capital city for the next 5 years, as it sustained the least damage from the severe weather events throughout the state.

Emergency management is absolutely overwhelmed with the ongoing situation, so the national guard and the US army stepped in to assist.

Historical rating of this storm

The Killeen-Austin-San Antonio tornado went down as the deadliest, most destructive tornado ever recorded on earth. It has the 2nd longest path length and was the widest tornado ever recorded with a 3.4 mile diameter. With a top wind speed of 377 mph, it also had the highest ever measured windspeed on earth. With a forward ground speed of 69.4 mph, it was also the 2nd fastest behind the tri-state tornado in 1925 with 73 mph. It was rated as the top of the top storms in history. However, some meterologists say the tornado should have been rated an EF6 due to the amount of damage, as some areas literally looked like they never existed before.

The governor of Texas has ordered that from now on, every home must have a basement or a storm shelter in order to be built. Furthermore, multiple cities will now get a new outdoor warning system, such as tornado sirens and other early warning devices.
