The flight landed at the alternate airport due to weather conditions. Can passengers get off the plane?

The flight was diverted to the alternate airport due to weather conditions, and passengers were not allowed to get off the plane.

Generally, diversions due to weather conditions are mostly due to thunderstorms, and thunderstorms come and go quickly, so usually the crew will not let you off, just add some fuel and leave immediately to disembark the passengers, which is very troublesome.

If there is heavy fog, this time is usually relatively long, a few hours is common, or even a whole day, so the crew will let the passengers off the plane.
