Rainbow appears above Parkland high school as teachers return to work for first time since mass shooting

Teachers reporting back to work at Marjory Stoneman Douglas High School on Monday for the first time since the deadly Feb. 14 mass shooting were greeted by a remarkable sight.

A rainbow appeared in the sky over the Parkland, Florida, high school as faculty members returned to the site of the tragedy to prepare for the official reopening on Wednesday.

WTVJ reporter Darryl Forges shared a photo of the stunning occurrence on Facebook.

On Sunday, many students and faculty members attended a voluntary orientation at Marjory Stoneman Douglas High School.

Students walked through the halls where 17 of their classmates and teachers were gunned down in order to collect their backpacks and other belongings that they left behind while fleeing the massacre.

Tears were shed and hugs were exchanged during the difficult return, with multiple students sporting T-shirts that read "Douglas Strong" and "Parkland United," according to the New York Times.

The gathering on Sunday was the beginning of a "phased reopening" of the school, according to Broward County officials.

Monday begins a two-day planning period for teachers and staff members ahead of students making their official return to the school on Wednesday for a modified schedule.
