The smog situation no longer applies in the Pilsen, South Bohemia and Hradec Králové regions and in the Vysočina.
“The threshold values of the 12-hour averages at the measuring stations have been exceeded for more than three hours, and we do not expect a further rise in the concentration of Saharan dust in the air,” meteorologists said on the X network on Monday.
In Moravia and Silesia, dust concentrations should decrease only after the passage of a cold front from the west in the evening. “During the afternoon and evening, we will disrupt the situation in other places as well,” added the ČHMÚ.
The ČHMÚ declares a smog situation when the 12-hour moving average of PM10 dust particle concentrations exceeds the threshold value of 100 micrograms per cubic meter at at least half of the stations in a given region and is not expected to fall below this value in the next 24 hours.
According to the ČHMÚ, concentrations of dust particles were particularly high in the Moravian-Silesian Region, where in several places even short-term, hourly concentrations of dust reached almost 200 micrograms per cubic meter.
When there is an increased amount of dust particles in the air, meteorologists recommend avoiding heavy physical exertion, especially for children and the elderly and people with chronic respiratory problems.
