For example, .25 miles (0.4 km) away from a 10 kiloton blast, the air pressure could exert a force in excess of 5 pounds per square inch (psi). This 5 psi (0.35 kg/cm2) "overpressure" is the same as a force of over 180 tons (160,000 kg) slamming against the side of a typical two-story house.

At the same place, there would be a wind of 160 miles per hour (260 km per hour).

Although your body -- out in the open and not inside a rigid structure -- could withstand overpressure up to 30 psi (2.1 kg/cm2), the winds accompanying an overpressure of as little as 2 to 3 psi (0.15 to 0.21 kg/cm2) could blow people out of a typical office building.
