The National Weather Service in Mount Holly issued the warning for gusty winds and low relative humidity, which is in effect from 7 a.m. to 6 p.m. Saturday.
A secondary cold front Tuesday will bring little opportunity for precipitation and another day of windy conditions across the region, forecasters say, setting the stage for risk of fire spread.

A ban on open fires in Northampton County will take effect Sunday. Charcoal and propane grills still will be allowed, along with fires in a fireplace or otherwise contained indoors.
The trend of above-average warmth continued Wednesday, with the National Weather Service reporting several high temperature records tied or broken at climate sites before noon. Thursday will threaten the record books again.
