Weather is being watched closely to confirm selected primary & alternate sites are good for return, and we’ll conduct another weather review about 24-hours before undocking to determine whether we are GO to proceed. More to come.

After separating from the space station, Crew 3 will make a splashdown off of the Florida coast around 12:37 am, Friday, May 6, 2022.
The decision is not final, because according to Kathy, NASA will review the weather ahead with 24 hours of undocking in order to confirm that the crew can return safely to Earth.
The decision to make the undocking on May 5 and the splashdown on May 6 was made by both SpaceX and NASA.
