Well, it looks like a chilly Halloween for local ghosts and goblins. In the wake of the strong moisture-laden frontal system that brought 78 millimetres of rain to our region this past weekend, a westerly onshore flow will bring unsettled conditions with showers and possibly flurries across the South Coast today, according to Squamish meteorologist Jason Ross. Ross said that an upper trough will develop on Tuesday, bringing another chance of isolated convective showers or flurries. "The air mass will be cold enough that flurries are possible down to a few hundred metres above sea level in the Squamish area if heavy showers develop," he said.
