1046 PM PDT Mon Sep 23 2019

...GUSTY NORTHEAST WINDS AND LOW RELATIVE HUMIDITY VALUES IN
MENDOCINO AND LAKE COUNTIES TONIGHT THROUGH TUESDAY NIGHT...

.A tight pressure gradient will yield strong offshore winds
across area ridgelines tonight and again Tuesday night. Drying
aloft will keep relative humidity from recovering efficiently.
Fuels remain receptive to fire despite recent rainfall and higher
humidity. Thus there will be an increased risk of large wildfire
growth tonight through Tuesday night.
