More than 50 counties of the districts of Pharaoh, braganza, real town, Guard, Coimbra, view, White Castle, Santarem Y Portalegre presents this Thursday a maximum rural fire riskaccording to the Portuguese Institute of the Sea and the Atmosphere (IPMA).
The IPMA also placed various counties of all districts of mainland Portugal in very high and high rural fire risk.
According to the IPMA forecast, the the fire danger will worsen in some regions of the continent at least until Monday.
In the coming days, mainland Portugal will face a situation of persistent hot weatherwhich should lead to heat wave in many areas of the territory.
“This situation is due to a eastern quadrant flow in an anticyclonic circulation located to the northeast of the Azores, extending in a ridge to Central Europe, which will carry a very hot and dry air mass over the territory of the continent”, according to the IPMA.
The forecast points to a rising temperature valuesespecially the maximum, with values above 35 degrees centigrade in most of the territoryexcept in some places on the western coast, where the values will be between 30 and 35 degrees.
In the interior, especially in the southern region and in the Tagus and Duero valleys, temperatures should reach values greater than 40 degrees starting Friday, being able to arrive locally at 42 degrees.
The minimum temperature will also increase, predicting the persistence of tropical nights (minimum above 20°C) in much of the territory.
“These meteorological conditions, also associated with low values of relative humidity, will also result in a significant increase in rural fire riskwhich should be in the maximum and very high classes in almost all of the North and Central interior and in the interior of the Algarve”, warns the IPMA.
A minimum temperatures this Thursday vary between 15 degrees (in Guarda and Viseu) and the 22 (in Portalegre) and the maximum between 30 (in Guarda) and the 39 (in Lisbon, Santarém and Évora).
Fire danger, determined by the IPMA, has five levels, ranging from low to high.
The calculations are obtained from the air temperature, relative humidity, wind speed and the amount of precipitation in the last 24 hours.
