The cumulative precipitation recorded by the meteorological station of the National Observatory of Athens / meteo.gr, which is located on the Plateau of Askifou in Chania, from 1 February until the morning of Monday 25th of the month – a period during which “Hioni” and ” Oceans “- reached 1,202 millimeters.
The previous monthly record in a residential area belonged to Grental of Norway with 1,190 millimeters, a record it kept since 1989.
Extremely high rainfall was also due to the “Ocean” in the rest of Western Crete, from Saturday (23 February 2019) until Tuesday morning (24 February 2019).
“Hioni” – “Ocean” twin destruction
According to the recordings of the network of automatic meteorological stations of the National Observatory of Athens / meteo.gr, from Saturday (23.2.2019) to Tuesday morning (26.2.2019) in the area of Semprona of Chania fell 40.9% of the average annual rainfall.
Very high are the corresponding rates for the rest of the prefecture of Chania, surpassing 31% of the Plateau Askyfou, Vrysses, Agios Pantes and Alikianos.
Another main feature of the bad weather was the stormy and very windy winds that lived mainly in the eastern continental segments, in the Aegean and in the western parts of the Corinthian Gulf.
Gusts of wind reached 100 kilometers per hour, and their duration was particularly impressive.
From 23/2 to 26/2 in the morning, bursts daily reached or exceeded 100 km / h, and the duration in consecutive hours, where the bursts exceeded 60 km / h.
The three reasons that Crete was “drowned” by the rains!
The strong rains that have fallen on Crete are generally due to a combination of three factors, said Kostas Lagouvardos, director of research at the Institute of Environmental Research of the National Observatory of Athens (NSA) and meteorological meteorologist, at the Athenian and Macedonian News Agency.
These three factors that have acted together are:
* The passage of a barometric low south of Crete.
* The existence of a cold gaseous mass in the middle layers of the atmosphere, about 5,000 meters, which favored intense instability. For this reason, there was also a major lightning activity on the island, but also on the sea, the Cretan Sea and the Libyan Sea.
* Topography, especially the extensive mountain ranges of Western Crete, further favors instability and hence the occurrence of heavy rains and storms.
“These three factors,” the scientist stressed, “have worked together for a long time, beyond 24 hours, resulting in the persistence of the phenomena, especially the heavy rainfall, for many hours over Crete, with the strongest phenomena in the west Island’s. This persistence has caused the great rainfall that fell to the west, resulting in very significant disasters. “
Mr. Lagouvard pointed out that “the predictability of the phenomenon was very good in that case, that is, from Saturday and especially Sunday morning, the forecast maps of the rain showed the unprecedented intensity of the expected phenomenon, for this reason the National Observatory of Athens had issued a warning, stressing the gravity of the situation. “
