A Tempestade Tropical Jerry desloca-se para Leste com ventos máximos sustentados de 64/65 km/h. Deverá rodar para Oeste, deslocar-se para Noroeste seguindo depois para Nordeste.
the structure of Jerry has evolved considerably during the last
several hours. Earlier today the cloud pattern resembled a sheared
tropical cyclone with deep convection mainly confined to the
eastern portion of the circulation. Recently...banding features
have become established and the cloud pattern is now much more
symmetric. The initial wind speed is increased to 45 kt based on
a Dvorak classification from TAFB.
The shear that has been plaguing the storm during the past couple of
days has apparently slackened...given the more symmetric structure.
However...water vapor imagery shows strong west-northwesterly
upper-level winds and drier air impinging on Jerry. These
unfavorable conditions should limit significant additional
intensification during the next few days. After 72 hours...
weakening should commence due to even stronger shear. It should be
noted that this intensity forecast is of low confidence since there
is a large spread in the guidance ranging from dissipation within a
few days...as shown by the HWRF and ECMWF models...to a hurricane
as indicated by the lgem.
Jerry is still moving eastward...but it will soon slow down and
meander when it becomes embedded in very weak steering currents. A
westward motion is forecast to begin by late Tuesday followed by a
northwestward motion on Wednesday when some ridging builds to the
north and northeast of the storm. After that time...the cyclone is
forecast to recurve ahead of an approaching trough. The new NHC
track forecast is shifted to the east of the previous one but lies
to the west of the multi-model consensus.

Parece que vai passar já sem ser tempestade tropicar, por cima de São Miguel.
Depressão Tropical Jerry: A Depressão Tropical Jerry encontrava-se às 09:00 UTC de hoje localizada a cerca de 1580 km WSW dos Açores deslocando-se para NE com uma velocidade de 15 km/h. Prevê-se que este sistema meteorológico ao deslocar-se para norte venha a perder intensidade, pelo que deverá afectar os Grupos Central e Oriental do arquipélago na madrugada/manhã de domingo com a classificação de Depressão Pós - Tropical. Assim, para domingo prevê-se um aumento da intensidade do vento (vento do quadrante sul com rajadas até 70 km/h ) e da agitação marítima (ondas de 4 a 5 metros do quadrante sul, passando a noroeste) bem como precipitação que por vezes poderá ser Forte. Sugere-se o acompanhamento da evolução da situação meteorológica através da página do IPMA da Internet (www.ipma.pt) e a obtenção de eventuais recomendações junto do Serviço Regional de Protecção Civil e Bombeiros dos Açores (www.prociv.azores.gov.pt).
