What is causing Balkans weather misery?

CNN) -- The Balkans are enduring the worst floods since records began 120 years ago. The situation is being exacerbated by the risk of landmines from the Bosnia war resurfacing.

Already 26 bodies have been recovered, and rescuers expect to find more as flood waters recede. Even though the intense rainfall subsided Monday, the disaster is far from over. CNN meteorologist Pedram Javaheri said flooding in the region will last at least another week -- and in some places, it could get worse.

Southern Europe is no stranger to heavy rain events: the low pressure system currently drenching the Balkan Peninsula was detached from the main weather pattern and is known as a "cutoff low." This meteorological event has slowly dumped more than 100 millimeters of rain in only a few days, leaving rivers swollen and towns underwater.
