Three EF0 Tornadoes Confirmed in Southern Manitoba

The Northern Tornadoes Project (NTP) has confirmed that three EF0 tornadoes touched down in southern Manitobaduring severe storms on August 5 and 6, 2025.

While all three tornadoes were considered weak by Enhanced Fujita (EF) scale standards, they were still capable of causing minor damage.

Grande-Clairière Tornado – August 5

The first tornado struck near Grande-Clairière, southwest of Melita, on the evening of August 5.

• EF rating: Default EF0 (weakest classification)

• Damage: No reported damage

• Details: Witness video captured the twister. Satellite imagery analysis is still pending.

Birds Hill Provincial Park Tornado – August 6

The second tornado touched down northeast of Winnipeg near Birds Hill Provincial Park at 5:06 p.m. on August 6.

• Path: 4.1 kilometres long, up to 270 metres wide

The confirmations came through a combination of radar data, witness reports, and ground and drone surveys conducted on August 7.

Satellite imagery reviews are still ongoing.

How Tornadoes Are Rated

The Enhanced Fujita (EF) scale measures tornado intensity based on damage.

• EF0 tornadoes: Winds of 90–130 km/h, typically causing light damage.

• Higher EF ratings indicate stronger, more destructive storms.
