TALLAHASSEE, Fla. — Florida’s unemployment rate is dropping again but the latest number does not reflect the potential impact of Hurricane Irma.

State officials on Friday announced that the state’s jobless rate in August was 4 percent and that 408,000 Floridians are unemployed. That’s a slight drop of .1 percent from the previous month. Florida’s unemployment rate is below the national rate of 4.4 percent.

The surveys, however, that are used to calculate the rate were done before Hurricane Irma slammed into the state.

During August, Florida added 20,100 jobs. The state has added more than 221,000 jobs in the past year. Only Texas and California have added more jobs in the past year.

Monroe County, which includes the Florida Keys, had the lowest unemployment rate in the state at 2.7 percent. The Keys have been badly damaged by the storm.
