Thanks to my friend Vince_and_Grace_fans who has not escaped these system. I followed this system very well. This was a real
Tropical Storm. Central Mediterranean temperatures were rather high, 26-27 ° C. The system was developed on the 20th day on the Tyrrhenian Sea as a tropical disturbance. On day 21 was a subtropical depression. On the evening of the 21st show a transition in a Tropical depression. In some moments, the LLC is partially exposed on the south side of the convection. However this has been observed many times in tropical depressions/storms. On the early hours of 22 the system has all the characteristics of a Tropical storm. It is a tropical storm. Symmetric warm core, Deep central convection, closed circulation, outflow bands are present. Unfortunately Ascat skips two passes in this phase at the probable peak intensity (estimate 40kt). However, during the landfall over the Tunisa Ascat shows winds of 35kt, consistent with a minimal tropical storm. During these system formation, almost stationary, he downloaded many hundreds of mm of rain offshore of the sea, and it was lucky, otherwise we could have severe floods on Lazio, Sardinia and Sicily. However, minimal flooding took place in Sicily and Sardinia. The landfall on Tunisia has caused serious and extensive floods, with a maximum of 225mm of rain Beni Khalled in a few hours and winds up to 62 km/h. The are
many damages, destroyed strees and 5 victims, but they could be more.
https://www.youtube.com/watch?v=IJGlLh4zMBEThe tropical systems in the Mediterranean, although ascertained by all of us, continue to be ignored by the main sources of tropical cyclones tracking. SAB SSD-Noaa inserted the Mediterranean between its basins a few years ago, but seems to have stopped observing this basin. Estofex (ESTOFEX: European Storm Forecast Experiment) warned about possible heavy rains on the central Mediterranean but underestimated the potential of this system, by simply describing it as a "warm core depression". Estofex staff are unprepared on tropical systems and this type of dynamics . The Mediterranean is not part of the NHC sector, but.. why this? What changes to them also include the Mediterranean? They are only 1-2 systems per year. On the other hand, geographically, the Mediterraeno is actually a branch of the north-eastern Atlantic. We should send numerous emails to attract attention, this situation has been going on for decades and seems to have no reason, a way out seemed to be SAB SSD-Noaa but this too was a disappointment. Usually in Italian media these systems have a little 'attention only when the meteo-models provide for these rather intense, but we forget that a simple tropical depression, although not strong in winds, can' cause severe floods, damage extend, fatalities.
