FORSYTH COUNTY — The Forsyth County school system has announced classes and schools will be closed Tuesday due to the threat of inclement weather from a fast-moving winter storm.

Jennifer Caracciolo, spokeswoman for the district, said 240-day staff should report to work only “if conditions are safe for travel.”

After-school activities and athletics, including several postseason girls’ high school basketball games, will not be held Tuesday.

Schools were closed to staff members Monday, who were supposed to work a professional development day while students enjoyed a long weekend for President’s Day.

That decision was made Sunday night, although sports practices were permitted from noon to 6 p.m. Monday.

Superintendent Jeff Bearden and administrative staff monitored the weather throughout the day, with Bearden making the final decision about classes Tuesday, according to Caracciolo.

Factors taken into consideration included timing and forecast predictions for snow and ice totals, building concerns and parking lot conditions.

The weather forecast calls for rain to continue into early Tuesday, with morning low temperatures below 30 degrees.

According to Caracciolo, Tuesday will not be an “online/itslearning day because we have two inclement weather days built into the 2014-15 school calendar, March 16 and April 3.”

“If we have to close school for three or more days, those days will be [online learning days],” she said.

In November, the Forsyth County Board of Education’s announced that no inclement weather days would be built into the 2015-16 school calendar.

School district personnel have assured parents and the community that itslearning — the virtual, interactive online teaching portal — has been and will continue to be successful in retaining high-level instructional time even when schools must close and students submit assignments from home.

The decision to nix snow days came after students stayed home for at least a week last school year during snow and ice storms.

Some of that lost time was made up via two built-in inclement weather days and the elimination of one early release day. But parents didn’t want to sacrifice spring break or extend the school year.
