..ELEVATED RISK FOR FIRE SPREAD TODAY
THERE IS AN ELEVATED RISK FOR FIRE SPREAD TODAY ACROSS SOUTHEASTERN
PENNSYLVANIA. MINIMUM RELATIVE HUMIDITY VALUES WILL DROP TO
AROUND 25 TO 35 PERCENT THIS AFTERNOON. THIS WILL BE ACCOMPANIED
BY NORTHWESTERLY WINDS WITH GUSTS UP TO 20-25 MPH. 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. CONDITIONS IMPROVE DURING THE
EVENING AS THE WIND DIMINISHES AND THE RELATIVE HUMIDITY
INCREASES.
OUTDOOR BURNING IS STRONGLY DISCOURAGED. BE SURE TO PROPERLY
EXTINGUISH OR DISPOSE OF ANY POTENTIAL IGNITION SOURCES, INCLUDING
SMOKING MATERIALS SUCH AS CIGARETTE BUTTS.
THIS FORECAST CONSIDERS METEOROLOGICAL, FUEL, AND LAND CONDITIONS
AND HAS BEEN DEVELOPED IN COORDINATION WITH STATE FIRE OFFICIALS.
