Slovenia: Heavy rains flood Ljubljana

After a quiet September, which on Wednesday was marked by the sun and very high temperatures in the afternoon, the weather in Slovenia last night showed its less pleasant side. In the late afternoon, northeastern Slovenia was hit by local storms with torrential rains and torrents, during which more than 50 liters of rain per square meter fell in a short time, and even more, violent events of the weather shifted over central Slovenia in the evening, even over the capital Ljubljana where such heavy rain has never been seen in a 160-year history of meteorological measurements, writes 24ur.com.

According to the Environment Agency of the Republic of Slovenia (Arso), 96 liters of rain fell at the meteorological station after Belgrade between 21 and 22 hours, and a total of 122 liters of rain per square meter, which exceeds the 250-year record. Prior to that, the worst rain in the Slovenian capital was measured on August 11, 1951, when 62 liters of rain per square meter fell in one hour, and the maximum rainfall of 5 hours was recorded on October 22, 2014, respectively 113 liters per square meter.

The Administration for Protection and Rescue of the Republic of Slovenia reports that the regional center of Ljubljana has received more than 2,700 calls from citizens from 20:00 to midnight. It flooded more than 500 buildings, as well as roads, parking lots and underpasses, and several personal vehicles were blocked in high waters. Ljubljana firefighters reported that they had intervened in 364 reported incidents as of 6 p.m.

As 24ur.com predictor Rok Nosan explains, a combination of volatile atmosphere and weak wind, which blew into the lower atmosphere (up to an altitude of about 2000 meters) from the northeast, and to a higher level from west, led to the formation of such violent storms. Namely, a weakened cold front was moving through Slovenia in the late afternoon and evening, and the weather was also slightly affected by a small cyclone at altitude, which was moving northeast across Central Europe. As a result, wind shear over Slovenia has increased, which we talk about when the wind changes direction and speed with altitude. Due to the weak winds at high altitudes, fortunately, the storms did not cover larger areas, and the front also weakened as it moved south of the country, so in many places in Primorska, Dolenjska and Bela Krajina there were only a rain sample.

A new change of weather, according to his forecasts, can be expected on Sunday, when the periphery of a very deep and wide cyclone concentrated near the British Isles will come. As a result, the southwest wind will intensify, bringing very warm and humid saturated air over the Mediterranean Sea. In the hilly world of western Slovenia, it will rain occasionally on Sunday morning, and a few drops of rain will be able to reach central Slovenia in the afternoon. This will be just an introduction to the very volatile weather early next week when citizens can again expect storms with longer rainfall.
