was on a VFR flight plan from Flin Flon to Brandon with the pilot and one passenger. The a/c flew into an area of low cloud and heavy rain, from which the pilot was unable to get out. The a/c was above the village of Pelican Rapids and the pilot decided to attempt a forced landing on a street. The pilot was able to land without hitting any power lines, but on roll-out, he hit a soft spot on the side of the road which caused damage to a wing, the horizontal stabilizer and the propellor. There were no injuries. A local police constable had seen the a/c above the village and he anticipated a possible landing, given the weather conditions, and cleared the street of vehicles. The nearest METAR from The Pas at the time of the occurrence showed 1000 foot scattered, 3000 foot broken, and 7200 foot overcast. UPDATE On departure from Flin Flon, the weather was reportedly a cloud ceiling of 2500 feet and at The Pas, the weather the pilot encountered was about 1500 feet, then it improved for a while before deteriorating. The pilot had received some weather information prior to the flight, including destination weather, but did not request a full weather briefing from the Winnipeg FSS. The en route weather had been forecast to deteriorate.
