Storm Forecast Valid: Mon 10 Mar 2014 06:00 to Tue 11 Mar 2014 06:00 UTC Issued: Sun 09 Mar 2014 18:44 Forecaster: TUSCHY
A level 1 was issued for Sicily and Malta mainly for excessive rain.
SYNOPSIS and DISCUSSION
There is no change in the synoptic setup with progressive troughs crossing N-Scandinavia from west to east. A mammoth high pressure area covers most of W/CNTRL and E-Europe with ongoing quiescent weather conditions forecast. A retrograde moving upper low over the S-CNTRL Mediterranean once again sparks numerous showers/thunderstorms over the warm waters of the far S-Mediterranean.
Similar to yesterday, Sicily and Malta probably see slow moving storms (less than 20 kn) which could dump lots of rain. Effective PWs increase to 15 mm east of Malta and that's where we see strongest LL convergence signals. Clustering storms with excessive rain are forecast and they could spread west/north to affect also parts of Sicily and Malta. Beside the rainfall risk, sleet/small hail, gusty winds and an isolated waterspout event are possible as well.
