NBC Montana checked in with rafting and lodging workers who say the rain is changing visitors' plans.
A worker at Glacier Park Lodge in East Glacier said people have not been wanting to go on their tours with the constant rain.
People are still coming through to stay at Glacier Park Lodge since the flooding started, but moving farther north is a problem.
"The majority of the frustration has definitely been with guests who are trying to get to St. Mary's," said Lauren Theune, an employee at Glacier Park Lodge.
An employee at the Campground of America in St. Mary's sent NBC Montana flood footage. This weather is even throwing off the locals.
"A couple people have said that they haven't seen rain like this in a long time," said Theune.
Making the commute to St. Mary's has been difficult because the Looking Glass section of Highway 49 is closed and it's the quickest way to get to St. Mary's.
Glacier National Park officials advise using caution while traveling in this weather. They said that there's rain on snow which can make some hazardous situations, so make sure you are prepared before you travel that way.
