National Weather Service United States Department of Commerce

Effective Tuesday, March 30, 2021, at 200 PM Eastern Daylight Time (EDT), 1800 Coordinated Universal Time (UTC), the NWS Weather Forecast Office in Miami, FL, (MFL) will change Fire Weather Forecast Zones encompassing Collier, Glades, Hendry, and Palm Beach Counties in south Florida. After this change, all fire forecasts and related products will use the new zone numbers and names shown below.

If March 30, 2021, is declared a Critical Weather Day, this implementation will be postponed to April 1, 2021.

These changes are intended to provide increased flexibility and improved accuracy of forecast, watch, warning, and advisory products in the fire weather program.

Four current zones will be converted into nine separate zones. These new zones are being divided to optimize issuance of hazard products for conditions that vary significantly near Lake Okeechobee and across Collier County due to sea breeze influences.

The new zones are as follows:
