News Forcasted drop in temperature prompts flash freeze warning SHARE ON: Andreas Pandikiu, contributor, Friday, Jan. 12th, 2018 Photo credit: Public Domain Pictures. A flash freezing warning has been issued for Bancroft. Environment Canada is forecasting a quick drop in temperature this afternoon, at which point today’s rain will turn to snow, with the possibility of a brief period of freezing rain. The weather agency says this could cause water and slush on roads, parking lots, and walkways to freeze, which could make them slippery and dangerous. You are being reminded to be extra careful when walking or driving.
