Oklahoma Union Schools are taking steps to help students stay hydrated as much of Oklahoma remains under a heat advisory this week.

The District says water will be available on school buses in the mornings, as well as on afternoon bus routes, although supplies will be limited. Students are encouraged to drink plenty of water and avoid wasting it.

School officials are asking parents to send children to school with a refillable water bottle they can use throughout the day and on the bus ride home. The district will have additional cups available for students who do not have a water bottle.
