July 2, 2006 19:00 South Johnville-Argyle, New Brunswick F2 Confirmed tornado around 22:00 UTC. Severe damage to power lines and houses. Downed trees. Heavy rain and hail 2-3 cm in diameter. NTP (2024) - A large set of photographs was sent which led to revisiting this case. Sentinel-2 and Google Earth aerial imagery show a long track with heavy forest damage and multiple buildings (all assumed barns) destroyed and later removed. Globe and Mail article also has local resident saying barn was flattened. Rating upgraded from F1 to F2. 19.5km 1.2km 0 0
July 2, 2006 19:25 Nashwaak Lake, New Brunswick F2 EC-Operations had noted that there was also damage reported in the vicinity of Miramichi Lake. Following the work on the South Johnville - Argyle tornado, this area was examined for evidence of damage. A long path entirely through forested areas was found using Sentinel-2 and Google Earth aerial imagery, with multiple large areas with most or all trees down (harvesting was clearly underway as seen in Google Earth imagery). The path has several curves but no sharp bends. It is likely that this tornado was caused by the same supercell, therefore the time was estimated as being 25 min following the start of the first tornado. This and the previous tornado are the widest tornadoes confirmed in Atlantic Canada. 22.8km 1.2km 0 0
August 15, 2006 18:00 Pokemouche-Evangeline, New Brunswick F1 Tornado impacted the area of Pokemouche and Evangeline. Hail, damaging winds and intense lightning were reported in the region. A tornado swept along a corridor of 20-50 metres wide and 3-5 kilometres long extending from Pokemouche through Evangeline. The tornado, estimated in the lower F1 range (wind estimated around 120 km/h), caused structural damage to a few properties and uprooted/snapped a few trees along the corridor. The sighting of the actual funnel cloud/tornado was reported by a few members of the public. 4.02km 50m 0 0
June 16, 2007 Petitcodiac, New Brunswick F0 The storm knocked down trees and hurled pieces of playground equipment and wheelbarrows long distances. In one incident, the twister picked up a trampoline from a front lawn and threw it 18 metres into a pasture. It also hurled two cast iron rockers (weighing more than 50 kg each) about the same distance. Made F-scale assessment based on description above and using wind damage table. 0 0
July 29, 2007 16:00 Grand Falls-Windsor, Newfoundland F0 Witnesses describe seeing tornado touch down in a remote area (possible across a lake) near Norris Point. No office follow-up as it didn’t appear to cause any structural or property damage. Time estimated from archived radar. 0 0
July 29, 2007 17:30 Gander Bay, Newfoundland F0 Reports were that it first touched down at Wings Point, on the NW side of Gander Bay, crossed the Bay, then moved over Main Point on the SE side of the Bay. A few snowmobile trailers were flipped over as it passed, as well as a couple of ride-on lawnmowers, and a residential deck. Several trees were snapped. An area of grass was also flattened. Associated with a severe thunderstorm outbreak on July 29, likely a supercell. Time estimate from archived radar. No injuries or fatalities. 4km 0 0
July 20, 2013 19:20 Jesmeg-Whites Cove- Cambridge Narrows-Codys, New Brunswick EF1 ECCC in Atlantic Region apparently did a survey but files are unavailable. Media did report that ECCC rated the tornado as EF1 however. Canadian Press articles had enough information to get a rough start location, and Landsat was used to determine the first half of the track. There were reports of barns down in a few locations but unclear to what degree and the quality of construction, so used lower bound of DOD8 (EF1). Tree damage seen via Landsat also supports only EF1. The second half of the track is estimated from videos of the tornado crossing the lake and damage near Cambridge Narrows and Codys. Radar from US side shows a clear mesocyclone with a supercell crossing the area, which provided the time. 24km 500m 150km/h 0 0
August 1, 2015 15:50 Sheephouse Falls, New Brunswick EF1 Satellite imagery review revealed a historical damage track through forested area. EF-scale assessment based on swaths of worst tree damage is DOD5 for DI C-T, with max wind speed estimated at 145 km/h. No ground survey conducted, no damage reports found. 4.69km 160m 145km/h 0 0
July 18, 2016 17:30 Saint-Quentin, New Brunswick EF1 About 120 ha. of trees blown down. 30,000 tonnes of fallen timber salvaged by J. D. Irving Co. Lower-bound wind speeds because of shallow ground in the area. Tornado moved from WSW to ENE. Black Brook, NB WSW of Boston Brook, NB. NTP (2024) - Satellite imagery review revealed the tornado damage track, with a length of 8.85 km and max. path width of 330 m. 8.85km 330m 145km/h 0 0
August 7, 2016 Grand Mira South, Nova Scotia EF0 A tornado was confirmed near Grand Mira South, Nova Scotia. 0 0
August 7, 2018 18:15 Knowlesville, New Brunswick EF1 Satellite imagery review of a storm track revealed a tornado damage path through forested areas. High-resolution aerial imagery was collected in August 2018. Damage assessed as EF1, with an estimated max. wind speed of 145 km/h, track length of 38.3 km and max. path width of 490 m. 38.3km 490m 145km/h 0 0

Upon NTP analysis of survey photos and drone imagery collected by the public, EF1 tornado damage was confirmed at a farm property in the community, with an estimated track length of 620 m, max. path width of 50 m and max. wind speed of 155 km/h. 0.62km 50m 155km/h 0 0
July 22, 2021 15:44 Antrim, Nova Scotia EF0 Witness near Antrim captured video of a tornado passing within a few kilometres and could see trees bending in the distance. No damage reported and satellite imagery review revealed no visible damage. The EF-Scale assessment is default EF0. 0 0

Information available insufficient to accurately estimate track length, max. path width and tornado motion. 110km/h 0 0
June 30, 2024 15:15 Carlow, New Brunswick EF0 House and tree damage was reported in the Carlow area after a storm passed through. No injuries were reported.
