Wednesday is expected to bring wet weather for most of Denmark as warm and humid air moves over the country once again. A few days ago, heavy rain caused traffic disruptions in both Kolding and Copenhagen, and similar weather conditions may be on the way. The Danish Meteorological Institute (Danish: Danmarks Meteorologiske Institut – DMI) has issued a risk bulletin regarding potential local cloudbursts and thunderstorms. A risk bulletin is the lowest level on DMI’s warning scale, which ranges up to very dangerous weather.
According to DMI, rainfall amounts could reach between 15 and 30 millimeters in just 30 minutes on Wednesday. In Jutland (Danish: Jylland), the warning will be in effect from 10:00 AM until 10:00 PM local time, while Funen (Danish: Fyn) should prepare for rain and thunderstorms from 1:00 PM to 9:00 PM. For the rest of the country—except for Bornholm—the warning is valid from 3:00 PM until midnight.
Meteorologist Anja Bodholdt from DMI explains that a cold front is moving into Denmark. This cold front is bringing warm and humid air from the southeast, which may cause temperatures in Zealand (Danish: Sjælland), Lolland, and Falster to reach around 26-27 degrees Celsius (79-81 degrees Fahrenheit) during the afternoon hours. Concurrently, the heavy showers and thunderstorms are expected to sweep in.
It is still uncertain how severe the downpours will be and which areas will be hit hardest. On Sunday, six cloudbursts were recorded in southwestern Jutland, Zealand, Funen, and Lolland. The highest rainfall was measured in Kolding with 32.6 millimeters, while Copenhagen experienced 27.8 millimeters, leading to the complete flooding of the Nordhavnsvej tunnel.
