What should be a warm, hot Valentine's Day business frenzy could turn menacingly cold this year for florists located in the U.S. South, northeast parts as well as along the East Coast. The snow storm may well be going out, but the road conditions continue to be icy and dangerous for flower deliveries.

"We are hoping it's not going to be too bad," Gina Zimmerman Fries, a member of the family that owns Jen-Mor Florist in Dover, told USA Today.

"We don't make money unless the trucks are moving," Tracy Callahan told Washington Post as she waded into knee-high snow with a shovel and tried to free the flowers. She also tried to chip away the ice surrounding the delivery van.

"Valentine's Day is the ultimate procrastinator's holiday," Matthew Rosenheim, president of Washington, D.C., jeweler Tiny Jewel Box, told CNBC. "The storm has the potential to have a major financial impact on the business."

Even major freight companies FedEx and UPS have issued service delay warnings by late Wednesday, which carried on Thursday for the South.

"The biggest problem with weather like this would be if the product didn't arrive. All you can do is not argue with mother nature and plan in advance," Sandy Baumann, co-owner of Nielsen's Florist in Darien, was quoted by CT Post.

Some business owners believed on Valentine's Day itself, they would be lucky to get calls from customers placing orders or receive them at their shops scouting for ready-made arrangments.

"I have a feeling tomorrow's going to be quite a wasted day, as far as people coming in," Catherine Amodio, owner of Creative Flowers by Amodio's, said.

Still most of them would do everything they can to make Valentine's Day 2014 worthwhile.

"We are ready for anything," Stephen Minoff of Hansen's Flower Shop said. "We just have to roll with the punches and work as a team to make sure Valentine's Day goes as planned and is the very best for the customers."
