For nearly 20 years, meteorologists had questioned the safety of these structures; however, they lacked incidents involving loss of life.
10 buildings were damaged, including a business that was nearly destroyed. [41] By May 13, roughly $1.6 million in disaster funds had been approved for housing and businesses loans.
A modular home, 3 regular homes, and several sheds, barns, and outbuildings were destroyed. Flights were grounded at Will Rogers World Airport as the northern edge of the supercell (containing hail up to 1.25 inches (3.2 cm), straight-line wind gusts up to 70 mph (110 km/h), and moderate to heavy rain) approached the area; the tornado turned right, away from southwestern parts of the city proper located within Oklahoma County, shortly before airport officials began evacuating employees and visitors at the terminals. Several vehicles were picked up and tossed nearly 0.25 mi (0.40 km) away from their previous location. No injuries took place at the school, though a horse was found dead between a couple of destroyed cars in this area.
Damage to an industrial complex, including a factory which lost parts of its roof.
Three months later, as homes were being built in the damage path, Marshall found their construction to be scarcely superior to that of the homes destroyed in the May 3 storm.
Several sheet metal buildings were destroyed. Oklahoma City, Oklahoma is slammed by an F5 tornado killing forty-two people, injuring 665, and causing $1 billion in damage.
The tornado outbreak of April 8–9, 1999, was a widespread tornado outbreak that affected the United States in early April 1999.
176 structures, including homes and businesses were damaged or destroyed including two destroyed homes in Warsaw, with many businesses and neighborhoods destroyed in Hamilton. Three homes were also damaged.
David Andra, a meteorologist at the NWS Norman office, said that, in drafting the enhanced warning, he wanted to "paint the picture [to residents in the areas that were to be affected by the storm] that a rare and deadly tornado was imminent in the metro area."
Several sheds were destroyed and homes were damaged. Caused damage to houses and mobile homes. You may need to download version 2.0 now from the Chrome Web Store. This page has been named "1999 Oklahoma tornado outbreak" for quite a long time now -- since 2004, as a matter of fact.
At one point, there were as many as four tornadoes reported on the ground at the same time.
Large-scale search and rescue operations immediately took place in the affected areas. [9][12], Conditions became highly conducive for tornadic development by 1:00 p.m. CDT as wind shear intensified over the region (as confirmed by an unscheduled balloon sounding flight conducted by the NWS Norman office), creating a highly unstable atmosphere.
14 homes were also damaged. [+], Doppler reflectivity: A National Weather Service NEXRAD radar image of central Oklahoma at 7:00 pm on May 3rd shows four tornadic supercell thunderstorms occurring simultaneously.

The 3 May 1999 Oklahoma City tornado was the largest death toll in over 20 years. Five coal cars were also knocked off a track.
According to a study by the National Oceanic and Atmospheric Administration (NOAA), seeking shelter in an overpass "is to become a stationary target for flying debris. Because Oklahoma has historically been climatologically prone to tornadic activity, Oklahoma City-area television stations KFOR-TV (channel 4), KOCO-TV (channel 5) and KWTV (channel 9) – each of which provided continuous coverage of the outbreak that spawned the Bridge Creek–Moore tornado and its ensuing aftermath from the event's start on the afternoon of May 3 through the evening of May 4 – have long relied on state-of-the-art radar technology and visual confirmation from news helicopters and in-house storm chasing fleets to cover severe weather events.
[26] Numerous industrial buildings were leveled in this area of the city. (In future issuances, tornado emergencies were issued within either the initial tornado warning issuance or a Severe Weather Statement providing updated information on a tornado warning already in effect.
May 3, 1999 Oklahoma/Kansas Tornado Outbreak. It was also the deadliest tornado ever recorded in the Oklahoma City metropolitan area; the previous record was held by an F4 tornado that affected southwestern portions of the city on June 12, 1942, which killed 31 people and caused $500,000 in damage ($11.5 million in (2020 USD) when adjusted for inflation). fD�w�z�&���$���-֊�ģ��I�7 ���̊�|W��'�v��O�i�T�i0�`P Z��k�
[7][17], As the supercell's mesocyclonic rotation began to rapidly strengthen at the cloud base, a tornado warning was issued for the counties of Comanche, Caddo, and Grady at 4:50 p.m. CDT;[18] one minute later, a small tornado roughly 25 yards (75 ft) in diameter − the first of 14 associated with supercell "A" (the National Weather Service Weather Forecast Office in Norman designated lettered names for the three tornado-producing supercells in the outbreak in storm surveys) − touched down seven miles (11 km) east-northeast of Medicine Park along U.S. Route 62. 5 homes, 4 barns, 2 grain bins, and 3 mobile homes were destroyed. A church was damaged and three tractor trailers overturned. Caused damage to ten farmsteads and a church. SPC analysis had detected the presence of a dry line that stretched from western Kansas into western Texas that was approaching a warm, humid air-mass over the Central Plains; the condition ahead of the dry line and a connecting trough positioned over northeastern Colorado appeared to favor the development of thunderstorms later that day that would contain large hail, damaging straight-line winds, and isolated tornadoes.
The F5 tornado killed 44 people in Moore, Oklahoma. [15] Tracking northeast, the storm strengthened and entered Comanche County shortly after 4:00 p.m.

While some of the damage through this area was rated high-end F4, low-end F5 was considered. One person was injured by the tornado. The most prolific tornadic activity associated with the May 3 outbreak – and the multi-day outbreak as a whole – occurred in Oklahoma; 14 of the 66 tornadoes that occurred within the state that afternoon and evening produced damage consistent with the Fujita scale's "strong" (F2–F3) and "violent" (F4–F5) categories, which, in addition to the areas struck by the Bridge Creek–Moore tornado family, affected towns such as Mulhall, Cimarron City, Dover, Choctaw and Stroud. A total of 40 people in Oklahoma were killed by the tornadoes on May 3-4, 1999 and another 675 persons were injured.
The American Red Cross had set up ten mobile feeding stations by this time and stated that 30 more were en route. The tornado proceeded through additional densely populated areas of Moore shortly thereafter, where several large groups of homes were flattened in residential areas, with a mixture of high-end F4 and low-end F5 damage noted in the survey. Despite these grim statistics, there were significantly fewer losses because of applied knowledge and new technologies developed through years of tornado research by NOAA scientists. By 7:30 pm, the The report acknowledged that federal construction code requirements needed to be revised above the then-current minimum standards to allow newer buildings to better withstand higher wind speeds consistent with tornadoes of lesser intensity than the one that devastated Bridge Creek and Moore, thereby lessening the degree of damage, fatalities and injuries that are probable in buildings of typically less reinforced construction. Two metal power line towers were toppled as well. 1 0 obj << /Type /Page /Parent 9 0 R /Resources 3 0 R /Contents 2 0 R /CropBox [ 18 0 594 792 ] >> endobj 2 0 obj << /Length 5123 /Filter /LZWDecode >> stream Several homes and barns were damaged, including one severely in Jefferson County.

[+], Damage paths and Fujita scale intensity: A total of 58 tornadoes were recorded in the National Weather Service Norman County Warning Area during the May 3rd outbreak. One house and several trees were damaged west of downtown Des Moines. [14], Paralleling along Interstate 44, the tornado moved into McClain County, where it crossed the highway twice at F4 intensity, killing a woman who was blown out from an underpass where she was attempting to seek shelter, after being dragged down the embankment by the intense channeling winds; her 11-year-old son − with whom the woman vacated their stalled car nearby − survived, staying held tight onto the steel girders of the overpass.
[21][22] About one inch (25 mm) of asphalt was scoured off a road by the violent tornado. Due to the higher standards for public safety, no one was killed by the 2003 tornado, a substantial improvement in just four years. A few farm equipment storage buildings, one barn, five grain bins, and a garage were destroyed.
