The German Meteorological Agency warns of extreme heat and the risk of wildfires
German weather service warns of extreme heat “The heat can be very stressful for the elderly and people in need of care,” the warning said. In densely built urban areas, additional pollution can be expected as night cooling is reduced.
Friday night it should be 22 to 17 degrees in northern Rhine-Westphalia, with temperatures dropping to 14 degrees only in the mountains. The heat warning is initially valid until 7:00 pm Friday. The DWT also pointed out that the risk of wildfires is high. The DWT map shows that the second highest alert level applies to most parts of the country.
Solar radiation increases ozone levels
Intense solar radiation also increased ozone levels on Thursday. At five measurement points, 180 micrograms of ozone per cubic meter of air was sometimes measured. From this value, people are informed. The state Environment Agency recommended ozone-sensitive people such as asthma to avoid outdoor work. “Athlete endurance programs should be postponed to early morning or evening,” the authority in Essex said.
