...Increased Risk of Rapid Fire Spread Later Today...

There is an increased risk for rapid fire spread later today
across portions of southeast Pennsylvania. Minimum relative
humidity values will be between 20 and 25 percent combined with
west to northwest winds of 10 to 20 mph with gusts up to 25 mph.
High temperatures today will be in the mid to upper 50s. These
conditions, along with the continued drying of fine fuels, could
support the rapid spread of any fires that ignite, which could
quickly become difficult to control.

Outdoor burning is strongly discouraged. Be sure to properly
extinguish or dispose of any potential ignition sources, including
smoking materials such as cigarette butts.
