__**Robotics Research: Hail storms in Montreal**__

A town outside Montreal has been ravaged with a hail storm that has left hundreds of thousands of dollars of damage in its wake. The damage was so extensive, some wondered whether a tornado hit the town of Huntingdon. Environment experts are investigating. In the meantime, the town's mayor, Stéphane Gendron, said he will ask the province for help with recovery costs. "We'll ask two things from the government. First of all, the decree to cover what is not covered by regular insurance," Gendron told CTV News Huntingdon. "And also a survey of all hydro poles because we discovered the poles that were knocked down were completely rotten." In just 10 minutes, 33 millimeters of rain and hail fell, incensed with winds gusting up to 100 kilometers an hour. Some people described seeing ice pellets the size of marbles hitting their window. Residents emerged from their homes Saturday to survey their neighbourhood and were shocked at the extent of the damage. Homes are flooded, hundred-year-old trees were uprooted, antennas were toppled and crops were all but ruined. "You can see all the damage -- it's all cut like it was cut by a knife," said farmer Albert De Martin, who estimated about 15 per cent of his crop was destroyed. "It's all damaged."
