The gusts on the Petrobras platform, in the Campos basin, reached 103 km/h. There’s a hangover alert on the southeast coast.
A large extratropical cyclone is moving over the ocean off the coast of the southeast region. This system tends to move away from Brazil, but causes strong winds on the ocean surface, which make the sea rough.
Hangover
Due to the strong winds produced by the cyclone, the Brazilian navy has issued a special warning for high tides on the coast of the southeast region, from Ilhabela on the coast of São Paulo to Linhares in Espírito Santo. There are conditions for waves between 2.5 and 3.0 metres.
This notice is valid until 21:00 on Friday 19 May
In addition to the rough seas, the Navy has also issued a warning for strong winds in the coastal area between Maricá, in Rio de Janeiro, and Vitória, in Espírito Santo, for the entire area up to about 555 kilometers offshore.
This notice is valid until 21:00 on Thursday 18 May.

Wind on Petrobras platforms
The Petrobrás oil rigs, located in the Campos Basin, in Rio de Janeiro, began experiencing strong gusts of wind caused by the extratropical cyclone on Tuesday afternoon. The most intense occur on the Albacora shelf, where many gusts reached speeds between 60 km/h and 80 km/h. But since dawn this Wednesday the wind is even stronger, with frequent gusts between 70 and 85 km/h. Around half past midnight a gust reached 92 km/h and at 1 am another gust reached 103 km/h
For the north coast of Rio de Janeiro and the Lagos region, the forecast is for gusts of 50 to 65 km/h
Lots of clouds on the coast of RJ
Most of the clouds in this cyclone are over the sea, but some reach the coast and can cause rain showers. This is what is expected for Rio de Janeiro this Wednesday May 17th. But the rain that will fall will be of little intensity and there is no cause for alarm.
