The Portuguese Sea and Atmosphere Institute (IPMA) issued yellow warnings for the nine islands of the Azores yesterday due to forecasts of “sometimes heavy precipitation, which may be accompanied by thunderstorms.”
In the case of the Western group (Flores and Corvo), the yellow warning is in effect from 8am local time until 8pm local time today.
The IPMA also issued a yellow warning for those two islands in the Western group regarding sea turbulence, with westerly waves of 6 to 7 meters between 11:11 a.m. local time and 5 p.m. local time.
For the Eastern group (São Miguel and Santa Maria), the yellow warning will be in force from 08:00 local time until 17:00 local time today because of heavy rainfall, which may be accompanied by thunderstorms.
The yellow warning, the least serious on a scale of three, is issued by the IPMA whenever there is a risk situation for certain activities depending on the weather.

The National Maritime Authority and the Navy warned yesterday of a “considerable worsening” of weather conditions and sea waves in the Azores starting Saturday. “The sea state forecast points to a considerable worsening of weather conditions and sea turbulence in the Azores archipelago between 00:00 on Saturday and 06:00 on Sunday,” the two entities said.
The forecasts point to sea turbulence characterized by “a swell from the West – Southwest quadrant, with a significant height” that could reach a maximum height of 13 meters, “with an average period varying between 12 and 14 seconds”, they warn. “Winds are expected to come from the South – Southwest quadrant, with an average intensity of up to 65km/h and gusts of up to 117km/h,” said the authorities, who recommend that the maritime community and the population take extra care, both when preparing to go to sea and when they are at sea or in coastal areas. The authorities call for strengthening mooring and “close monitoring” of moored and anchored vessels. They call on the population to avoid walking by the sea or in areas exposed to sea waves, such as the protective jetties of ports, cliffs, or beaches.
