Excetuando-se a estação do Pico Santos de Cima, que está localizada numa zona alta, a estação do Aeroporto de Santa Maria (LPAZ), que fica a 96 m de altitude, foi a única que registou vento de tempestade tropical (vento médio), no limite inferior (≥39 mph ≈ 63 km/h).
 
Mesmo no fim do seu percurso sub-tropical, Patty gera agora convecção forte.

Ia postar isso agora mesmo:

Na atualização das 21h00 UTC, Patty mantinha a sua intensidade.

Subtropical Storm Patty Discussion Number 7
NWS National Hurricane Center Miami FL AL172024
900 PM GMT Sun Nov 03 2024

After being devoid of deep convection for much of the day,
thunderstorms have reformed near the center of Patty. Therefore,
Patty will hold its subtropical storm designation for now.
The
initial intensity is held at 40 kt in deference to the earlier
scatterometer data. However, strong vertical wind shear, dry
mid-latitude air, and cool sea surface temperatures should weaken
Patty during the next couple of days. No changes have been made to
the latest NHC intensity forecast.

The storm is moving eastward at 15 kt and is forecast to move
eastward to east-northeastward for the next couple of days. Patty
is still expected to open into a trough near or over western Europe,
and only minor adjustments have been made to the official track
forecast.

Tropical Storm Patty Discussion Number 8
NWS National Hurricane Center Miami FL AL172024
300 AM GMT Mon Nov 04 2024

Patty has continued producing deep convection since the time of the
previous advisory, although the convective structure has recently
degraded slightly on the latest infrared images. The infrared
satellite images and an 03/2138 UTC ASCAT pass depict a more compact
cyclone with a confined radius of maximum winds than earlier in the
system's life. Patty is also no longer co-located with the
upper-level low that was earlier responsible for its hybrid
characteristics. Based on these observations, Patty has made the

transition into a tropical storm. The earlier ASCAT pass showed
tropical storm force winds as high as 39 kt in the southern
semicircle. The initial intensity is therefore held at 40 kt.

Deverá ser uma TT de curta duração, perdendo as suas características tropicais à medida que avança para águas tendencialmente mais frias, em direção à Península Ibérica.
