A  dry front is headed for the Valley come Monday morning.

The front will bring gusty north winds, extremely low humidity and continued hot temperatures through Monday afternoon.

 North winds surging over 25mph and gusting over 40mph will combine with rising temperatures and low humidity  causing for rapid to explosive wildfire growth.

The National Weather Service in Brownsville has issued a "Red Flag" Warning for Brooks, Hidalgo, Jim Hogg, Starr,  and Zapata counties from 10am until 6pm Monday.

A "Fire Weather" Watch has been issued for coastal Cameron, Coastal Willacy, Inland Cameron, Inland Willacy,  and Kenedy counties from 10am until 6pm Monday.
