The Azores regional delegation of the Portuguese Institute for Sea and Atmosphere (IPMA) has given the name Therese to a new storm on the horizon, set to bring rain, strong winds, and rough seas from the evening of Tuesday, 17th March, through to Saturday, 21st March, with the Centre and South of the country, including the Algarve, expected to be hardest hit.
According to the IPMA, “an increase in cloud cover is expected across the entire territory, with the possibility of showers from late afternoon onwards, more likely along the southern coastline”.
From 18th March, as the storm system rotates, it is expected to bring “bands of instability over mainland Portugal, leading to a spell of showers, more likely in the Centre and South, particularly along the coast”, which “may at times be heavy and accompanied by thunderstorms”.
Winds will shift between the easterly and southerly quadrants, depending on the storm’s position, and are expected to strengthen, blowing at times strongly along the coast and in higher ground, with gusts of up to 65 km/h.
A temporary increase in sea agitation is also forecast along the western seaboard, with north-westerly waves potentially reaching heights of around four metres.
IPMA has not yet issued any weather warnings in connection with the situation, citing “a high degree of uncertainty regarding the position of this storm in the coming days, which will influence both the location and the amount of rainfall that may occur”.
