Cold front brought severe weather across N Adriatic region – Oct 11, 2013

A cold front was crossing the MDT risk area of Day 1 Outlook 11/10/2013 over northern Mediterranean this morning and brought heavy rain and strong winds into W Slovenia, NE Italy and NW Croatia. 30-60mm was accumulated over larger area in 12 hours between 00 and 12 UTC, while along the CRO/SLO border just north of Kvarner bay radar estimated even around 150-200mm of 12hr total. Unfortunatelly no weather stations are in that area, the closest one Matulji (source: Istramet) just N of Rijeka, Croatia reported 104mm/12hrs which fits into the radar estimation.
