.DISCUSSION...
Drier conditions and stronger winds will contribute to an increased
fire danger risk today across the region. A drier air mass moving
through will limit moisture recovery, keeping relative humidity
values in the low to mid-40s across southern coastal plains and
around low to mid 50s elsewhere.
Winds are expected to strengthen, ranging from 20-30 mph, with
higher gusts, further exacerbating fire danger conditions by
enhancing fire spread potential. Given these expected conditions
and KBDI values remaining above 550, an RFDSJU has been issued
due to the elevated risk of fire spread.
