Funnel cloud near Ottawa: “normally no danger”
Environment Canada issued a weather advisory Wednesday afternoon to reassure the people of the federal Capital Region after a whirlwind was seen in the skies above Rockland, east of Ottawa.
L es weather conditions are conducive to the formation of “funnel clouds” like the one that was seen in Rockland. Environment Canada adds that this phenomenon is “caused by a low rotational movement due to rapidly forming clouds or a lightning storm.”
Environment Canada is reassuring, stating that “this low rotation normally does not pose a danger near the ground”, but is careful to add that we must still be on guard because it “could intensify and cause a weak tornado like a terrestrial bomb. ”
Although the onshore storms generally do not cause significant damage, “they can be intense enough to uproot trees, damage roofs or transport debris over short distances.”
