Conteúdo: 	Several strong sea-level oscillations in the southern region of Brazil with periods in the
range of tsunamis, but attributed to atmospheric disturbances, have been publicized in
the media or in scientific articles in recent years. However, only a few were registered by
instruments. On October 29, 2019, a squall line, linked to an atmospheric storm and a positive
jump in atmospheric pressure, spread from south to north along the coast of Santa
Catarina. The atmospheric disturbance generated, through Proudman?s resonance mechanism,
at least two tsunami-like waves with heights greater than 0.70 m and periods around
15 min. These waves were recorded by a network of tide gauges, allowing to monitor their
evolution and transformations for more than 200 km. Although there were no reported
fatalities, there were significant material losses linked to this occurrence. The objective
of the present work is to analyze and connect atmospheric conditions and wave signals in
order to further understand the circumstances leading to the formation of this type of event
in the southern coast of Brazil.
