Fallowfield, ON F2 Tornado of June 23, 2002

City of Ottawa

The tornado was only on the ground for 1 kilometre, but it had a width of 500 metres and passed directly through Fallowfield. The twister snapped and uprooted trees, caused structural damage to almost all houses in the village, and sent debris scattering throughout. At one home, a large pice of lumber was found piercing the bottom of an in-ground swimming pool that was full of water.

Throughout the village, garages, barns and outbuildings were demolished; one barn was torn entirely from its foundation and destroyed, and Mowat’s silos on the south side of town were heavily damaged.

Figure 1 depicts the surface observations at 5:00 pm EDT, which shows a cold front extending into southern Quebec and central Ontario. This cold front, sitting roughly over Ottawa, became the focus for intense thunderstorms in the afternoon of June 23rd, which ultimately led to this F2 tornado.
