Strong and prolonged heatwave will hit Greece from Monday 21 Julywith temperatures that will reach or even exceed 45 degrees Celsius in some areas.
Three -day “fire” – when the phenomenon peaks
According to the provisions of the National Observatory of Athens/meteo.gr, the most difficult time is expected to be from Tuesday 22/7 to Thursday 24/7, while in some areas thermal pressure will be maintained at very high levels until Friday.
The transfer of hot gas masses from North Africa to the Balkans is stepping up the scientists’ concern, with meteorologist Costas Lagouvardo referring to “one of the strongest heatwaves of the last summer”.
Comes the most severe summer heatwave – mercury “flirting” with 46 ° C – 33rd nights in Athens
Nights without dew – high humidity and air pollution
Particular concern is the fact that the temperature will remain at high levels in the evening, with thermal burden being felt mainly in large urban centers. At the same time, increased humidity rates and reduced air quality (due to concentration of suspended particles) may aggravate the state of healthy groups.
Red alarm – Warnings for serious dangers
The state and scientific agencies are emitting a risk signal, as the population’s health is expected with an increased risk of heat stroke, even for healthy people. At the same time, the chances of power outages due to overload of the network are increased.
As the Observatory points out, the sun exposure is required, sufficient hydration, avoidance of physical fatigue, as well as stay in cool or air -conditioned spaces.
The following days – what do maps show
The temperature divergence of 850 HPA (about 1,500 meters) from the average of 1991–2020 reaches +10 ° C, one of the highest values of recent years. This, combined with the dry atmosphere and the weak winds, creates the conditions for extreme surface temperatures.
