Aí está ela, é oficial!
A 29ª tempestade da época, o record a ser quebrado. :winner:
Veremos então como se comportará nos próximos dias.
De tempestade sub-tropical passará a tempestade tropical, mantendo-se nos 50 nós de intensidade nas próximas 120h.

Theta continues to exhibit a mix of tropical and subtropical characteristics. The cyclone has a fairly compact radius of maximum winds with a central dense overcast over the northern portion of the circulation. However, there is a strong subtropical jet located just to the south of Theta, and strong upper-level winds in the surrounding environment in the presence of an upper trough. Based on this inconclusive data, Theta is being maintained as a subtropical storm for this advisory. An ASCAT-B overpass this morning revealed 50-kt winds in the northwest and southwest quadrants, with several 55-60 kt wind vectors, some of those vectors outside of the deep convection making them more believable. Based on this, the initial advisory intensity has been set to 60 kt.

Theta is still expected to transition to a tropical storm later today as it separates from the upper-level trough. Although Theta will be tracking over progressively cooler SSTs and within moderate wind shear conditions, the air mass is expected to remain unstable for the next couple of days, which should be supportive of deep convection. Therefore, little change is strength is indicated during that time. Some weakening is anticipated later in the forecast period as the airmass becomes more stable. The NHC intensity forecast is higher than the previous one primarily due to the higher initial intensity, and is near the IVCN and HCCA consensus models.

As rajadas máximas de 75 nós (força de furacão) e ventos máximos de 60 nós (110 Km/h) estão previstos durarem só até amanhã às 12h. Daí em diante a intensidade irá diminuir até à maior proximidade à Madeira, no Sábado à tarde, e nessa altura os ventos máximos previstos serão já na ordem dos 40 nós ( >70 Km/h):
