Breaking News: 18 & Over Mixed Nationals going to short sets due to weather

I wrote a few days ago that the weather forecast for Mobile for this weekend's 18 & Over Mixed Nationals didn't look good for Friday,  an 80% chance of thunderstorms, and the current forecast still calls for scattered thunderstorms and 60% chance of precipitation.

Looking closer, the hourly forecast says a 40-60% chance of rain nearly all day which might make it difficult to get many matches in as any gaps in the rain may allow the courts to dry, right before it starts to rain again.

I'm guessing as a result of this forecast, I'm hearing that the USTA is preemptively going to a shorter scoring format from the start to get as many matches in as possible on Friday, and then be able to catch up on Saturday if needed.

I have not heard specifics, but I'm guessing it will be a format like what was done in Arlington using a modified Fast 4 with sets to 4 with no-ad, a set tie-break at 4-4, and either a set tie-break at 3-3 or just first to 4, and a match tie-break for the third set, perhaps just to 7 points instead of 10.

It is unfortunate it comes to this, I really was hoping the forecast would improve and the rain would clear out sooner, but this is perhaps the best that can be done given the site selection.

I will post more or update this as I learn more.

Update: Sets 1 and 2 will have a standard set tie-break at 4-4.  Here is the text sent to captains in an e-mail:

We will be playing best two out of three short sets with NO AD scoring and a 10 point coman tiebreak rotation if teams split sets. Teams will play to the first to 4, win by 2. If the set reaches 4-4 teams will play a 7 point coman tiebreak.
