(CNN) Florida candidates in hotly contested races for governor and US Senate are adjusting their campaign plans as Tropical Storm Michael is poised to slam the state's Panhandle.

Florida Gov. Rick Scott, the Republican nominee for Senate, declared a state of emergency Sunday and activated 500 Florida National Guard troops in preparation for the storm. Scott will be leaving the campaign trail for the "next few days," a campaign spokesperson told CNN.

Sen. Bill Nelson, the Democratic nominee, will be meeting with emergency management officials in the Panhandle tomorrow "to make sure local officials have everything they need," a campaign spokesperson told CNN.

The forecast indicates the tropical storm could strengthen into a hurricane by early Wednesday and will likely target the Panhandle later that day, according to CNN meteorologist Gene Norman.
