PALM BEACH COUNTY, FL (WFLX) - South Florida residents have called to report smoke and falling ash.
We've also received photos of the smoke which can be seen in the western part of Palm Beach County and northwest Broward County.
The U. S. Fish & Wildlife Service is conducting a prescribed burn in the Arthur R. Marshall Loxahatchee National Wildlife Refuge.
But wind is pushing the smoke into Broward. Ash has fallen as far south as Lauderhill. Residents could experience periods of ash for the next couple of hours according to the National Weather Service.
Complaints have reached the Broward Sheriff's Office which urges anyone with respiratory and/or cardiovascular ailments and the very young and elderly, "to limit their outdoor exposure until the conditions improve".
