With cold temperatures looming, several Iowa school districts have already canceled classes on Monday.
In the metro, districts are still waiting to make that call.
Officials with the Des Moines School District said they must make a decision on whether to cancel school by 6 a.m. Monday morning at the latest, but anticipate announcing the decision much sooner.
There isn't a specific temperature that must be reached for school to be called off.
District leaders say they collaborate with other districts and keep in mind students that have to ride the bus or walk.
"We know it's an inconvenience for families. They will have to make other arrangements for child care that day, they might have to plan around work. We know that it's a decision that has a huge ripple effect across the community,” said Phil Roeder with Des Moines Public Schools.
School closings strictly due to cold weather are rare.
The Des Moines school district hasn't canceled school because of the cold in five years, and has only done so three times in the past 40 years.
