By the strong wind, the gathered wind rolls have been stacked on the two floor or even the rooftop of the residential buildings. Many residents are trapped in the house for several hours and can not go out. The victor and backyard of about 150 homes in Victor, California, are surrounded by thousands of wind rolls. According to reports, the National Weather Service issued a strong wind warning, the wind speed can reach 70 miles per hour (about 113 kilometers). But many local residents say that despite the fact that tumble is common in Victor, it is the first time that such a large-scale outbreak has occurred. Local residents were carrying gloves and carrying pitchforks in an attempt to stop the invasion of the tumble. It is reported that there are about two tons of wind pits planted outside the houses of one household, and more than 10 staff members spend about 1.5 hours to clean them up. Tumbleweed is a prickly vegetation. It can roll freely in open space under the impetus of wind, and its sharp thorn can scratch the skin, which makes them extremely difficult to handle. Local residents said: we clean up almost every time, the gale will bring a wave. And they will hide from people. You can go outside and see that they can fly overhead.
