The Brazilian Navy, through the Navy Hydrography Center (CHM) and multiple collaborators, has issued a warning predicting the formation of a cyclone with possible subtropical characteristics, starting on the 23rd, when it may be classified as Subtropical Depression. The formation of the cyclone is associated with the establishment of a convergence zone over a region where the sea surface temperature is being observed between 26°C and 27°C. If the intensity of the observed winds reaches or exceeds 63 km / h (34 knots), the phenomenon will be reclassified as Subtropical Storm “Kurumí”, an expression in Tupi-Guarani that means “boy”. The nomenclature will be officially established by means of a Special Notice published on the CHM website, according to the list of names contained in the Norms of the Maritime Authority no. 19, available at https://www.marinha.mil.br/dhn/?q= en / norms- legislation.
The probable area of formation of the subtropical cyclone will be on the high seas, between the north of the state of Rio de Janeiro and the south of the state of Espírito Santo, with displacement initially towards the south, affecting the weather and sea conditions between the states of Santa Catarina and Bahia, starting on the 23rd in the morning. Winds are expected with direction from Northeast to North and intensity up to 87 km / h (47 knots) on the high seas, between the state of Rio de Janeiro, north of Arraial do Cabo (RJ) and the state of Bahia, south Caravelas (BA), between the 23rd morning and the 25th. Winds are also expected with direction from Northeast to North and intensity up to 61 km / h (33 knots) on the high seas, in the state of Bahia, between cities of Caravelas (BA) and Ilhéus (BA), between the 23rd in the morning and the 25th.
The winds may cause sea agitation resulting in direction waves from Southeast to East and height between 3.0 and 4.0 meters at sea, between the state of Santa Catarina, north of Laguna (SC) and the state of Rio de Janeiro, north of Arraial do Cabo (RJ). Maritime agitation is also expected resulting in direction waves from Northeast to North and height between 3.0 and 4.0 meters at sea, between the state of Rio de Janeiro, north of Arraial do Cabo (RJ) and the state from Bahia, south of Caravelas (BA), between the 23rd in the morning and the 25th.
The development and deepening of the cyclone may reinforce the convergence of humidity over the DELTA and ECHO areas, causing large accumulations of rain over the coast of the state of Espírito Santo and the south of the state of Bahia and over the maritime area where the phenomenon operates.
