Update: Friday, 2/24/2023, 5:15 pm to all Head Coaches and Principals

Due to the unsafe weather conditions, UCI campus leadership has made the decision that all outdoor events this weekend should be moved inside or canceled. As a result, we can no longer plan to have students outside as their home base, canopies or not, for tomorrow’s competition.

Thankfully, UC Irvine is not canceling our event.  In place of setting up home bases in the Physical Sciences Plaza, we are being directed to have all students and parents report to the Pacific Ballroom and the Student Center to set up their home bases.  The Ballroom will be set up with chairs for our awards ceremony later that night.  Teams can also use the lobby and any other open spaces in the Student Center. Please note that all teams will need to share this space, so please be thoughtful of your fellow competitors in your actions and in terms of how much space you take up.  Just as in before, participants must not block emergency exits or walkways.  If you are asked to move, please do so immediately.  Registration for head coaches will now take place outside the Pacific Ballroom.

Students may travel on foot or via private vehicle to arrive at their events throughout the day.  Please plan for a 15-minute walk to the Physical Sciences Plaza from the Student Center and Pacific Ballroom.  Umbrellas and rain attire are still definitely needed.

Your Park-by-Plate registration will work for the Student Center Parking Structure.

Please do your best to communicate this information with all expected attendees so that we get everyone safely to where they need to be in the morning.  If you are coming via bus, please direct your driver to the new drop-off location.  We have sent an email to all official coaches and principals, and have additionally texted all head coaches with a request to check their email.

We understand that the timing of this communication is a challenge for all parties.  To assist everyone in finding the right location, please see the maps below.  We will try to have staff on hand in the morning to help redirect any participants who show up at the original drop-off location.

We remain hopeful for a great event even with these extenuating circumstances.  And, again, we are deeply thankful that UC Irvine is not canceling our event at this time.
