This current hook echo with pronounced couplet makes that clear:30 Sep 2026 10:22 +0000at://did:plc:gcmtkmllc3ou26che7kqagyo/app.bsky.feed.post/3mwq4qzvemk2hhttps://bsky.app/profile/bramvantveen.bsky.social/post/3mvrwedw6tc2kYesterday there were many waterspouts in the Gulf of Genoa, and quite a few of them were associated with Doppler-detectable circulations:18 Sep 2026 10:08 +0000at://did:plc:gcmtkmllc3ou26che7kqagyo/app.bsky.feed.post/3mvrwedw6tc2khttps://bsky.app/profile/bramvantveen.bsky.social/post/3mv5tpbge7s2pAn earlier supercell just east of Corsica also produced a number of low-level circulations, in this loop I'm counting 3 small ones:10 Sep 2026 10:27 +0000at://did:plc:gcmtkmllc3ou26che7kqagyo/app.bsky.feed.post/3mv5tpbge7s2phttps://bsky.app/profile/bramvantveen.bsky.social/post/3mv5sxymwcc2pInteresting couplet over Pianosa Island currently @federicopavan.bsky.social10 Sep 2026 10:14 +0000at://did:plc:gcmtkmllc3ou26che7kqagyo/app.bsky.feed.post/3mv5sxymwcc2phttps://bsky.app/profile/bramvantveen.bsky.social/post/3mtu4yed63s2qWe had a strong tornado in France today, moving through Pomas, with a clear TDS and debris ball. Besides this one, we had another highly likely TDS a bit farther east, southwest of Montlaur @corentinaugris.bsky.social . Additionally, many mesovortices were apparent in the subsequent QLCS.24 Aug 2026 20:21 +0000at://did:plc:gcmtkmllc3ou26che7kqagyo/app.bsky.feed.post/3mtu4yed63s2qhttps://bsky.app/profile/bramvantveen.bsky.social/post/3msinmewrfs2gFor volumetric renderings, this monster supercell from South Dakota is one of my favourites. Look at the size of that BWER and region of strong cyclonic (in)flow! This storm produced hailstones up to 15 cm, 100 mph RFD winds and an EF2 tornado.07 Aug 2026 13:22 +0000at://did:plc:gcmtkmllc3ou26che7kqagyo/app.bsky.feed.post/3msinmewrfs2ghttps://bsky.app/profile/bramvantveen.bsky.social/post/3msgfjurtm222A look at the very large hail producing supercell over NE Poland this afternoon:06 Aug 2026 15:52 +0000at://did:plc:gcmtkmllc3ou26che7kqagyo/app.bsky.feed.post/3msgfjurtm222https://bsky.app/profile/bramvantveen.bsky.social/post/3mrz5nqr44k2nA beautiful rotating convective structure passed through northern Finland yesterday. In at least one region it downed a lot of trees: https://www.tilannehuone.fi/tehtava.php?hash=03c5c73f22947a07e427a348c9cb449401 Aug 2026 09:26 +0000at://did:plc:gcmtkmllc3ou26che7kqagyo/app.bsky.feed.post/3mrz5nqr44k2n
