At Least 14 Dead In Massive Athens Flooding; As Much As 15 Inches More Rain In Forecast
Unfortunately, with human-caused climate change, these kinds of devastating events have become far more frequent. With the Earth warming by around 1.1 to 1.2 C above pre-industrial averages, there are now four times as many instances of extreme weather than there were as recently as the 1970s.
What this means is that anywhere around the world now, the hammer of severe weather and related damages is four times more likely to fall than in the past. That the tempo of such events is now greatly increased. All thanks to continued fossil fuel burning, atmospheric CO2 levels that will average around 407 ppm over the coming months, the heat that these greenhouse gasses are continuing to add to the Earth’s climate system, and a failure to transition swiftly enough to more sustainable practices and zero carbon energy sources to prevent ramping damages.
Major Rain Event Strikes Athens — With More Severe Weather in the Forecast
Today, the major blow appears to have fallen on Greece. To the west of this country, over the Mediterranean, a cut off low is creating instability throughout the region. An intense, thick, moist warm air flow is moving in from the south. This warm and very water dense air is then colliding with a colder air mass to the north. Upper level instability is feeding powerful convection erupting in the atmosphere above Greece. And this convection is producing some mountainous thunderheads.

Last night, torrential downpours dropped 2-15 inches of rain over the outskirts of Athens. A biblical flood of water ripped through the region — rocketing vehicles down roads, prompting more than 600 calls for water rescues, killing 14 people, and leaving streets flooded or buried in mud while depositing cars into trees or on the tops of dwellings.
The rains stretched over a broad area from Greece to the Turkish coast — spurring declarations of emergency throughout the area. As with many of the increasingly fierce new disasters, it will take weeks or more to get a final tally of the total damages. But this event is probably not over.
Unfortunately, the cut-off low is expected to continue to circulate near this already flooded region for the next 3-4 days. Forecasts call for additional rainfall totals of up to 15 inches as the low churns and continues to generate outsized convection over an already hard-hit area.
