Severe flooding today in Catania, Sicily. At least two deceased and one missing person and significant material damage.

Yes, the floods in Catania, Sicily

from 24 Oct 2021 and onwards, have been pretty catastrophic - while pretty quiet in the international media reporting.

Due to powerful, large thunderstorm complex, of which one rose right over the area. In total and at the most Etna Nord station reported 600 mm rain. Catania got 300+ mm on 25 Oct 2021 - because the complex weather pattern later shifted in such a way, that the thunderstorms moved constantly in from east to west, right against the coast of East Sicily (Syracusa, Augusta, Catania, Giarre).

In the town of Lentini, just south of Catania, I remember that within 1 hour only - a whopping 147.4 mm came down, and 237 mm within 3 hours (24 Oct 2021)

This weather situation later spawned a subtropical system "Apollo" - located south of Sicily - which now is active (28-29 Oct) affecting Sicily with more rain (up to 227 mm in Syracuse, today), but isn't as bad or particularly dramatic compared to the first storm event from 24-26 Oct, which lead to the widespread floods.



The above Facebook video, collects different footages from the flood events in Catania into one. Especially the first scene, shows how the waters pour from the center of Catania (Piazza Duomo) into the (lower seated) fish market - truly impressive to watch ! Oh and yes, it happens at least once a year... albeit this time the total rainfalls where unusual high half the amount you get during a whole year - which happens perhaps 3+ times per decade (is my loose estimation)


Here below
you can see that extreme amounts of rain fell within 72 hours (24-26 Oct 2021)

After the flood 27 Oct 2021, near the harbor in the city of Catania, just a couple 100 meters away from wherer my husbands friend and ex-wife lives.

BOSNIA & HERZEGOVINA

Severe flooding caused significant damage in Sarajevo, the capital of Bosnia & Herzegovina after uninterrupted torrential rains that have hit the region since Thursday. Dozens of people were evacuated from their homes on Friday in the Sarajevo suburbs of Otes and Rajlovac and in the city of Konjic, some 50 kilometers further south. Other areas in the vicinity of the Bosna and Neretva rivers and their tributaries also reported damage.


Sarajevo without power​

The rising waters caused power outages in much of Sarajevo as residents of the capital went without electricity for hours.

Elektroprijenos, the power transmission company, said the grid had been hit by rain in many places and the continued precipitation was not helping efforts to reroute power. By evening though, power had been restored to much of the city.

The only certified medical oxygen-refilling plant in the country, part of the German Messer Group, was evacuated after it flooded.

"We could not save the equipment," Avdo Delic, the general manager of Messer's branch in Bosnia, told The Associated Press. "We had to save lives." He added: "Water came fast like a tsunami and it is fortunate that the Civil Protection was there with rescue boats."

Delic expressed concerns that Bosnian hospitals could run out of oxygen cylinders to treat COVID-19 patients unless the operations are restored elsewhere.

Bosnia, with a population of 3.5 million people, has a vaccination rate of under 20%, one of the lowest in Europe. On Friday, officials reported 1,100 new daily coronavirus infections and 32 deaths.

Landslide in Sicilia Italy



Flash flooding has turned roads into rivers in the port city of Catania, on the Italian island of Sicily.

The situation is "very critical," Giuseppa Maria Spampinato, a government official based in Catania, told CNN on Tuesday. From the view of her office's window, Spampinato said the main street in the city -- Via Etnea -- appeared completely flooded.

In Canada the town of Merritt, British Columbia (population: ~7000) has been evacuated due to massive flooding.



Nearby several major highways have collapsed as well.

It's a pretty dire situation. The government isn't sending out crews to repair the roads yet because they're worried there's worse to come.
