A strong whirlwind at the leading edge of a storm front or squall line.
- ‘As we raced westward to intercept, we came across a gust front with a number of gustnados.’
- ‘The gustnado typically forms along the leading edge of a thunderstorm outflow boundary called a gust front.’
- ‘That same day, Bobby Prentice had two side and the rear van's windows blown in by a gustnado north of Atwood, Kansas on Wednesday.’
- ‘I did sell some nice video of the gustnado and hail at the farmer's house to The Weather Channel.’
- ‘This tornado, like the others, gusted out, and we continued to watch a series of gustnados form after the main tornado in the outflow region of the storm.’
