Heat Safety Tips to Remember

Today's Records and Climate Data

The Heat Wave shows no signs of giving way as flash drought conditions continue across the entire Four State Region. As a result, much of the region is under a Burn Ban at this time. The wildfire threat will continue.

A Heat Advisory remains in effect across our entire Four-State Region through at least Thursday, as afternoon heat indices will approach 110 degrees through much of this week. Heed all heat safety protocols if you plan to spend extended time outdoors!

Warm and muggy conditions will continue overnight, as temperatures fall only into the upper 70s to near 80 degrees. Southwest winds will maintain speeds of 5 to 10 mph.

With oppressive heat expected to continue through much of this week, remember these heat safety tips.
