With thunderstorms in the forecast for Saturday, Mayfest has prepared for a potential change of Dillo Day venue.

In the event of thunderstorms, Mayfest will decide 5 a.m. Saturday whether to move the performances inside Patten Gymnasium and alert students with a university-wide email. The National Weather Service reported Thursday night likely thunderstorms for Saturday until the evening and a 70 percent chance of precipitation.

Mayfest spokeswoman Bri Hightower said that in the event performances are moved into Patten, only 1,200 undergraduate students with WildCARDs will be admitted to the concert. Graduate students, faculty, staff, guests and non-students will not be admitted.

In the event of a rain call, some of the Mayfest activities will be moved to reserved campus buildings, including Annenberg Hall. Hightower said the second stage and Dillo Village activities such as hookah and body painting would need to be canceled.
