Heavy rains can be annoying for the individual out in it but its good for Israels aquifers, the Kineret and farmers crops. The snow in the Golan will hopefully give the ski resorts what they need to open brining them in some money and of course when the snow melts it flows into the Kineret. The rains even saved a soldier when a parachutist was blown off course and end up landing in Gaza and the terrorists couldn't snatch him because the heavy rains made it difficult to get to him. So thanks to the rain there is only 1 soldier in Hamas hands and not 2.
