Wedding website & Covid

Maybe something along the lines of:

"Due to the uncertainty that COVID-19 has bestowed upon us world-wide, it is at this time that we are awaiting further instruction on whether or not we will be able to proceed with our event. As of now, our event is as scheduled. Please check back often as we will be updating our site with any new information that we receive from our venue regarding possible postponement. We love you all and we greatly appreciate your patience."

Of course you can just use it as a template. Doesn't have to be exact but I do hope that it gives you some kind of idea of what you'd like to say.

I would just say "With the ever changing rules and regulations for COVID 19 there is a chance our event may have to be postponed. We are currently moving forward with our plans and we will contact you if plans change."

You're welcome!
