"The ground is already incredibly soaked and the forecast appears to be well... even wetter," said Stephanie Elder, community representative for the American Cancer Society office in Paducah.
Elder said the decision was made before noon today by event co-chairs Frank Blackburn and Sue Padget.
Everything will run as planned, Elder said, with Relay beginning at 5 p.m. Friday and ending at 5 a.m., Saturday.
"We will have the luminaria ceremony as planned, but modified because of the fire risk with candles," Elder said. "We will still have lots of activities throughout the night as well as food and drinks being sold by the teams."
The National Guard Armory is located on Rochester Avenue in Marion.
