According to Rui Oliveira, ANPC operations officer, "during the night period there was a decrease in the number of occurrences compared to what had been recorded since the beginning of the alert." "From the beginning of the alert [12:00 on Thursday] until 08:00 today there were a total of 1039 occurrences that engaged 3,847 operational," said the operating. The districts that registered the greatest number of occurrences were Coimbra, Lisbon, Viseu and Porto, all with more than 100 occurrences.
The district of Coimbra was the one that registered more occurrences , followed by Lisbon, Viseu, Porto and Aveiro. The Civil Protection added that "There are no injuries to register so far". According to information from the National Civil Protection Authority (ANPC), 2435 operational and 919 vehicles were mobilized. The great majority of occurrences are relative to tree fall, as well as to the fall of elements of construction in built structures and to floods of structures or surfaces by intense precipitation.
According to information available on the IPMA website, the districts of Viana do Castelo, Braga, Porto, Aveiro, Coimbra, Leiria, Lisbon, Setúbal, Beja, Faro and the North Coast of Madeira are in yellow warning until 6:00 p.m. The Portuguese Institute of the Sea and the Atmosphere foresees for today in the North and Center regions periods of very cloudy sky, becoming usually little cloudy from the middle of the afternoon. Helena, the sixth storm since the start of winter, shook Galicia on Friday with all its intensity activating the orange alert on land by heavy snowfalls located in the province of Orense and the red warning on the Atlantic coast by waves that came to reach the ten meters. The forecast forced to cancel the classes in fifty schools of the provinces of Lugo and Orense, where thicknesses of twenty centimeters of snow were recorded, which left about three thousand schoolchildren without class.

The ANPC advises that people adopt a series of preventive and self-protection measures, including ensuring the clearing of rainwater drainage systems and the removal of dirt and other objects that may create obstacles to the free flow of water. Drivers are warned to take extra care on the roads and to be aware of ice and snow in affected areas, while in coastal areas fishing, water sports and coastal walks are not advised until the weather improves.

Already in the middle of this afternoon the storm Helena finally appeared. As a result of a low-pressure system in circulation in southern Greenland, the storm is significantly affecting mainland Portugal.

The low pressure associated with frontal surfaces, especially in the north-west of the continent, is creating conditions of great atmospheric instability, which is according to the most recent forecasts in periods of heavy rain (showers), mediated by strong winds that in some moments reach 100 km/h and strong sea turmoil.

In the center, in a chaotic beginning of the month of February, the production of ripples up to 9 meters high is planned on the west coast of Portugal, north of Sines, in a west-northwest direction. What is truly frightening and worrying is the energy associated with the ripple, in addition to the storm tide, the so-called Storm surge that can contribute to the rise of the ocean and promote the formation of shorelines. Some beaches may lose huge amounts of sand due to the strength and intensity of this process.

There is also a veritable gale, from 70 to 80 km/h and bursts up to 110 km/h in the continental range that extends from Viana do Castelo to Sintra , and may eventually cause damages typical of these situations. As for precipitation, it will be in the form of downpours, predicting the occurrence of thunderstorms stimulated by frontal occlusion and associated convective instability lines.

The critical period is expected to take place between 12 and 21 hours on Friday, February 1, where the districts of Viana do Castelo, Braga, Porto, Aveiro, Coimbra, Leiria and Lisbon will be under red warning. In the previous and later periods, the alert in these districts will be orange, maintaining until Saturday, moment in which the effects of Helena will have to diminish considerably. Until then, rest assured and watch the evolution of the weather.
