FARMINGTON — Students will not return to Lydia Rippey Elementary School in Aztec until Thursday as crews continue to clean up from damage caused by last week's thunderstorm.

Heavy rainfall, hail and wind rolled through San Juan County on Wednesday evening, flooding buildings and knocking out power.

Flooding forced the Aztec Municipal School District to cancel school on Thursday. Classes at all schools expect Lydia Rippey resumed Friday.

Rain damaged up to 12 classrooms at Lydia Rippey, as well as hallways and the gym, Superintendent Kirk Carpenter said on Friday. He said crews have been working since Thursday to clean up water damage.

"Obviously, the biggest thing is making sure everything is done professionally and carefully," Carpenter said. "It's not a clean-and-shampoo process."

The staff is scheduled to return to the school Wednesday to prepare for students, and classes are expected to start the following day.

To make up for the lost instructional time, Carpenter said administrators will likely modify the schedule to extend hours on certain days. Once that information is finalized, it will be communicated with parents, he said.

About 475 students are enrolled at the elementary school on Rio Pecos Road in Aztec.
