A coloured subdistrict outline identifies a point report in that subdistrict; it does not confirm flooding across the whole subdistrict. · Corroborated means at least two different publishers reported a similar level in the same subdistrict within 12 hours. · A solid fill shows an observed flood extent supplied with polygon geometry. · Tap a coloured area to see water depth, time, and corroborating source count. · One wave per metre of water at the labelled point
