Two EF0 tornadoes in NB on June 30
NTP investigation, including our first-ever ground/drone survey east of Quebec, has concluded that two tornadoes occurred in New Brunswick on the afternoon of June 30. The first tornado at Carlow caused house and tree damage while the tornado at Centre Glassville 5 minutes later caused a longer and wider path of just tree damage. EF0 ratings are preliminary pending analysis of high-resolution drone imagery.
