Ciclone Mediterraneo in approfondimento a sud della Sicilia,sul mar di Gabes.

ESTOFEX 13/01/09 :-Warning-Sicily, Malta, southern Italy, western Greece-
Active convective weather is found around the low pressure system between Tunesia and the Balkan. A plume of warm air surges into southern Italy and beyond, with 0-1 km theta-w values of 15°..
This is when the highest CAPE is present of about 1000 J/kg and capping is forecast to be weakest. Deep layer shear of 20-25 m/s is forecast over 0-6 km and 1-8 km, sufficient to sustain long-lived MCS and development of supercells. 0-3 km SREH is enhanced to >200 m²/s² and a factor of two higher at the warm front itself, where however predicted CAPE is lower or absent.
The main threat of the storms is large hail. Secondary is the possibility of isolated tornado occurrence, given 0-1 km shear is at least 10-15 m/s, relatively low LCL heights, and weak downdraft CAPE. The highest potential is over Sicily and southern Italy. Waterspouts are possible also in weaker shear.





Continua il pesante maltempo al sud a causa dei fortissimi venti (superiori a 50 nodi nello Ionio e asud della Sicilia) e delle abbondantissime precipitazioni anche superiori ai 200 mm)che il ciclone sta portando.Alcune celle temporalesche che si formeranno durante il suo transito potrebbero essere piuttosto violente.
A differenza di un normale ciclone extratropicale,questo ha una warm core (cuore caldo).
