The National Weather Service included screen shots from that video on its Grand Rapids Facebook page expl. An unusual weather phenomenon called a “gustnado,” which looks like a small tornado ...
A gustnado is a brief, shallow surface-based vortex which forms within the downburst emanating from a thunderstorm. [2] The name is a portmanteau by elision of " gust front tornado ", as gustnadoes form due to non-tornadic straight-line wind features in the downdraft ( outflow ), specifically within the gust front of strong thunderstorms.
A tornado was reported on the south side of Hobart, although it was later determined to be a gustnado instead. [5] As the night progressed, a squall line developed in Western Texas and steadily organized as it moved eastward overnight producing more severe weather. [6] The main day of the outbreak was March 17.
The English word has been reborrowed into Spanish, referring to the same weather phenomenon. Tornadoes' opposite phenomena are the widespread, straight-line derechos ( / d ə ˈ r eɪ tʃ oʊ / , from Spanish : derecho Spanish pronunciation: [deˈɾetʃo] , 'straight').

Outflow boundary on radar with radial velocity and frontal boundary drawn in.. An outflow boundary, also known as a gust front, is a storm-scale or mesoscale boundary separating thunderstorm-cooled air from the surrounding air; similar in effect to a cold front, with passage marked by a wind shift and usually a drop in temperature and a related pressure jump.
Four tornadoes were reported across northern Germany and the Netherlands, one of which may have been a gustnado. The worst tornado, which was rated T4 (F2), snapped or uprooted hundreds of trees near Marienthal , Brandenburg, Germany.
A mesocyclone is a meso-gamma mesoscale (or storm scale) region of rotation (), typically around 2 to 6 mi (3.2 to 9.7 km) in diameter, most often noticed on radar within thunderstorms.
