From the Henderson Fire Department:

The City of Henderson has requested us to burn the vegetation from the levee. We will be conducting this controlled burn tomorrow night, September 14th. We will start burning at approximately 6:00 P.M. and will last most the evening. Please avoid the areas around the levee during the burn, and keep all windows closed as a large amount of smoke is typically generated during this event. Right now the winds will be coming out of the South at 10-11 MPH tomorrow evening. Please spread the word, and as always, we appreciate your cooperation!
