Citing the potential for extreme heat conditions, the Columbus City School District will initiate an early dismissal for all students Tuesday, Aug. 28.

Interim Superintendent John Stanford made the call Monday, Aug. 27, as temperatures are expected to reach 90 degrees Tuesday afternoon, according to a news release from the district.

All high school and middle school students will be dismissed starting at noon, the release said. Students in elementary, K-6 and K-8 schools will be dismissed starting at 1 p.m.

All students will be served lunch before they are dismissed.

Afternoon buses will run about 2.5 hours earlier, the release said. Families should make alternative plans to meet children at the bus stop early or arrange for early pickup at the school.

After-school sports and extracurricular activities are canceled for Tuesday afternoon.

Latchkey will still be open and ready to welcome students at 1 p.m.

Teachers and staff will remain at the buildings until the end of the regular day, according to the release. Faculty and staff will be able to work in the limited cool/air-conditioned spaces. Teachers also will assist in supervising any students who cannot be transported home early.

The precautionary dismissal is only for Aug. 28, the release said. Stanford and other district leaders will continue to monitor building conditions and make decisions about future early dismissals as early as possible to give families as much time as possible to plan for schedule changes, the release said.

Columbus Public Health reminds residents of ways to stay healthy and safe in hot weather:

•Drink plenty of water – do not wait until you are thirsty.

•Stay inside in air conditioning whenever possible. If you do not have an air conditioner, use movie theatres, malls, libraries and other public places that are cool.

•Avoid beverages with alcohol, caffeine and sugar because they will dehydrate you.

•Eat light meals.

•Wear lightweight, light-colored clothing and a hat.

•Stay in the shade.

•Limit your outdoor activity to morning and evening hours.
