On Friday, August 3, 2018, an EF4 tornado hit Alonsa, Manitoba. It was the strongest 2018 tornado in North America.

At 4:00 p.m., a low-pressure system was on the Saskatchewan/Manitoba border. Another low-pressure system was coming up from North Dakota. The surface heating from Manitoba terrain enhanced the systems and ultimately led to rapid supercell development.

At 8:15 p.m., the tornado touched touch near Alonsa, with winds reaching speeds of 275 km/h. The twister travelled for 15.7 km, reaching widths of 1.2 km. The twister flattened several homes and buildings, causing around $2 million worth of damage.

Large items, including vehicles, building fragments, and panes of glass were blown into Lake Manitoba. The province brought an excavator machine to remove the debris from the beach area, but many of the larger items couldn't be retrieved from the water.

The Alonsa tornado was the first EF4 since Canada switched to the Enhanced Fujita scale.
