The storm, which has a chance to escalate to a hurricane, is expected to douse South Florida with heavy rains and winds between Sunday and Monday morning.
If the storm stays on its projected path, it could be making an impact on the Miami area about the time the Marlins are scheduled to arrive home from Los Angeles.
Like the rest of Florida, the Marlins are monitoring to see if the weather will cause their flight to be either delayed or canceled for a day.
"We don't know anything yet," manager Ozzie Guillen said. "We have a day off Monday anyway. Sunday to Monday we're supposed to arrive the same time the storm is coming. So we have to wait and see what is the deal.
"If we stay, we stay. If we had a game Monday, it would be a little bit different. Major League Baseball will have to get involved."
