This backward tornado burst to life in the wake of another odd twister, which was unusual in that it looped back over its own path, CNN reported. Tornadoes tend to travel from west to east, because the prevailing winds in the U.S. travel in that direction and thus push storm systems that way. However, tornadoes can sometimes turn back on themselves as they lose strength; in this case, the tornado completed a full loop over its original path before dying out.
As the looping tornado died down, the backward-spinning twister appeared a few miles southeast of Loveland, just before 10:30 p.m. Smith told CNN that both tornadoes were likely active for a brief period.
A weather service warning called the tornado "large and extremely dangerous" and noted that it was "nearly stationary or moving very slowly south." It warned people located in Loveland, Grandfield and Devol that "This is a PARTICULARLY DANGEROUS SITUATION. TAKE COVER NOW!"
According to the NWS, nearly all tornadoes in the Northern Hemisphere have winds that whip counterclockwise around a central point; this motion is known as "cyclonic." But in about 1% of cases, twisters spin in the opposite direction; these are called anticyclonic. (In the Southern Hemisphere, cyclonic tornadoes spin clockwise, while anticyclonic ones spin counterclockwise.)
It was unusual enough to see a backward-spinning tornado, but the cyclone's lack of movement was also odd, Smith told CNN. And radar suggested the storm was strong enough to chuck debris thousands of feet into the air, even though anticyclonic tornadoes are often relatively weak.
Thankfully, the tornadoes mostly traveled over farmland, according to recent updates issued by Tillman County Emergency Management on Facebook. There have been no injuries, deaths or extensive structural damage reported, according to CNN.
Oklahoma has seen more than two dozen tornadoes this week. On April 27 and 28, a "slow-moving, but potent" storm triggered at least 27 tornadoes in Oklahoma and Texas, with 24 confirmed in Oklahoma, the NWS reported.

In the area you have selected (Oklahoma) cyclone (also known as hurricane or typhoon) hazard is classified as medium according to the information that is currently available. This means that there is a 10% chance of potentially-damaging wind speeds in your project area in the next 10 years. Based on this information, the impact of cyclones should be considered in all phases of the project, in particular during design and construction. Project planning decisions, project design, and construction methods should take into account the level of cyclone hazard. Note that damages can not only occur due to wind but also cyclone induced heavy rainfall and subsequent flooding as well as coastal floods in coastal areas. Further detailed information should be obtained to adequately account for the level of hazard.
Climate change impact: Global average tropical cyclone wind speed and rainfall is likely to increase in the future, and the global average frequency of tropical cyclones is likely to decrease or remain unchanged. It is possible that the frequency of the most intense tropical cyclones will increase substantially in some ocean regions (IPCC, 2013). The present hazard level in areas currently affected by tropical cyclones may increase in the long-term. Projects located in such areas should be robust to future increases in cyclone hazard.
After construction is complete, plan to purchase a long-term hazard policy to protect your investment against cyclone wind damage, especially if it covers other significant hazards in your project area. Keep in mind multiple location policies can be an economical means of covering diverse risks across multiple locations. During financial planning, budget such a policy and prepare for potential premium increases resulting from higher risk levels in the future (for example, under climate change).
Context- In general, buildings constructed from masonry and reinforced concrete can withstand cyclone winds better than wood frame construction, although it is important to consider building design for cyclone wind alongside other hazards that might be present in the project area.
The most common, and often most costly, damage from wind is to the roof of a property. Complex architectural features (e.g., cupolas, lattice work, etc.) add visual interest, but they also tend to increase wind turbulence and the overall vulnerability of the structure. In general, wind pressures are highest at the corners of roofs.
An intense cyclone can bring torrential rains and have embedded severe thunderstorms that are accompanied by tornadoes. Buildings damaged by wind often suffer water damage as well. Water driven by hurricane-force wind can enter a building through otherwise sealed openings, and rain entering through a damaged roof can compromise the inside of the building and in some cases expose the building to dangerous mold.
Note that strong wind is not the only cause of direct physical damages from tropical cyclones. Wind-borne debris often initiates or enhances damages to a structure. Extensive damage can also be induced by heavy rainfall and subsequent inland flooding and, in coastal areas, by coastal floods and beach erosion, especially after the roof and/or windows or other openings are compromised by wind-borne debris.
Mitigation- Throughout the project from design to construction, consider all available mitigation strategies to reduce your wind risk from cyclones. Balance the cost of mitigation features with the long-term savings via reduced damage and lower cost of repair and replacement.
Further detailed information should be obtained to account for the risk from hazards related to tropical cyclones. Be sure to review the ThinkHazard! assessment for related hazards in this region: storm surge (coastal flood), river flood, and landslide.
Investigate national building codes for strong winds in your project area. Also determine from your local authorities whether local building codes override national codes, in particular along the coast where winds from cyclones are strongest. Be responsive to national and local building code requirements for wind hazards as following these codes may considerably reduce losses due to cyclone winds.
Start by consulting with widely accepted building code organizations such as the ICC (International Code Council) to access commercial and residential code (ICC/IRC) standards pertaining to your project.
Carefully consider roof construction in the design phase and select high quality materials in the construction phase. The most important construction measures to minimize wind damage to a roof include: proper installation of plywood sheathing, bracing of roof trusses, and use of hurricane straps.
The use of wind and impact resistant coverings to protect windows, doors, and other openings from breach by wind-borne debris can greatly reduce damage and loss from a tropical cyclone, particularly when a project is near other buildings (especially medium to high-rise construction), trees, and/or other surface obstacles. High-impact resistant glass can greatly reduce glass damage where debris is prevalent. Properly-rated storm shutters can be installed for use over windows and smaller openings. The tops and bottoms of doors can be reinforced using bolt kits. Garage doors and larger openings can be properly reinforced.
As a part of comprehensive risk management, consult the International Property Maintenance Code (IPMC) to assure your project has long-term resilience to wind damage. Be sure to plan for proper roof maintenance post-construction.
As a part of a long-term maintenance strategy, identify and remove small trees and branches from larger ones that could fall on the building walls or roof, or on nearby power lines. Identify and repair loose or damaged building components such as sheathing, soffit and fascia, shingles and roofing, brickwork, and jutting building features such as chimneys.
Special Considerations- Consider including a safe room in the design phase of your project. A safe room (wind shelter) provides a space to seek refuge and can provide an additional level of protection. Safe rooms are most effective atop the concrete slab foundation or garage/basement floor. Safe rooms built below grade provide the greatest protection, but must be designed to avoid accumulating water during the heavy rains that often accompany cyclones. A safe room must also be built to withstand flying debris even when the rest of the building is damaged or destroyed.
During the design and construction phases, thoroughly review the emergency response procedures laid out by your local and national governments and, if necessary, make changes to project design and implementation to account for these procedures. These procedures will have already taken into account the significant hazards inherent to your region, including cyclone wind hazards and other related risks to your project.
