All District 200 after-school activities are canceled Tuesday due to weather conditions. The District 200 Board of Education candidate forum is also canceled.

The new date for the forum is not yet determined.

The National Weather Service's winter storm watch for this area started Tuesday afternoon, when a combination of rain, snow and sleet switches over to all snow by Tuesday night. Although there is a "higher than usual amount of uncertainty with respect to snow accumulations," several inches are "probable," according to the latest forecast.

More problematic than the snow is the wind, forecasters said.

"Heavy, wind-whipped, wet snow could result in very low visibilities and difficult travel," the Romeoville-based weather service said. "Heavy snow could impact the late afternoon commute so persons planning travel should anticipate potentially significantly elevated travel times."
