Waterbury School District Snow Day Predictor
The odds of a closing or a delay on the next three school mornings in Waterbury, measured against Waterbury's own big snow morning of 6.5 inches.
Will Waterbury close tomorrow?
How Waterbury calls a snow day
When the call comes
Every attempt to reach a decision by 5:30 a.m.
“Every effort is made to inform our families as early as possible, but due to the unpredictable nature of severe weather events, a decision may be made in the morning. The District makes every attempt to reach a decision by 5:30 a.m.”Source
How families hear
By phone call, text message, email, the district website, social media, local TV and radio.
“ParentSquare: WPS utilizes the ParentSquare mass notification system. ParentSquare allows administrators to notify families by phone, text and/or email.”Inclement Weather Information
A 2 hour delay
On a delay morning every school starts 2 hours late.
“If WPS delays the start of school due to weather conditions, the school day will begin two hours later than the school's regular start time, and dismiss at the usual time. Morning buses will run two hours later than normal. Morning preschool will be cancelled.”Delay schedule
A snow day is a day off
Waterbury closes rather than going remote.
“students will have a traditional snow day. There will be no in-person learning, and state law does not allow remote learning on snow days to count toward the 180-day minimum.”Source
Making up a lost day
Added onto the end of the school calendar.
“Any such days will be added onto the end of the school calendar.”Source
