The California Retailers Association President warned consumers to shop early this holiday season due to supply chain bottlenecks.

"Shop early. If you've got certain gifts in mind…I would definitely purchase them early and have some patience," California Retailers Association (CRA) President Rachel Michelin told Fox News. 

WATCH:

Cargo ships stuck at California ports have contributed to a supply chain crisis nationwide. Trucking and warehouse shortages, as well as pandemic-induced e-commerce shopping sprees, have all fueled the crisis.

"The Ports of Los Angeles and Long Beach account for 40% of the imports nationwide, so this is the gateway for many national retailers," Michelin explained. "While it's focused on California, this is national problem."

Michelin explained that because ships stuck in California ports have merchandise meant for retail stores, the retail industry has had to adapt.

"We're trying to do everything we can from the retail industry," Michelin explained. "We have products coming out that might have been there from last year." Additionally, some bigger retailers are using their own chartered planes and smaller ships to get merchandise, and the  California Retailers Association is "working with the Port of Los Angeles to try to move cargo as quickly as possible," she said.

Beyond shopping early and having patience, Michelin also recommended consumers shop at small businesses this holiday season. 

"Anything you can do to support local businesses and small businesses this holiday season I think is really important," the CRA president said.

"They're impacted by this too, because they have goods on these cargo ships." Michelin also said that CRA is encouraging shoppers to buy gift cards if they can't find the perfect gift.

In terms of how long the crisis will continue, the CRA president said: "I think you've got the immediate crisis, which is between now and probably mid-January, but we're looking at supply chain challenges well into 2022."
