URGENT - FIRE WEATHER MESSAGE
National Weather Service San Francisco CA
320 AM PDT Fri Jun 22 2018

...Gusty northerly winds coupled with hot temperatures and low
humidity values Saturday through Sunday evening...

.High pressure will build inland through the weekend and bring a
combination of gusty northerly winds, hot temperature and low
humidity values late morning Saturday through Sunday evening.
Northerly winds of 15 to 30 mph with gusts up to 40 mph are
expected. Humidities will drop into the low to mid teens or
locally into the single digits with poor overnight recoveries.
Temperatures in the mid to upper 90s as well as isolated triple
digit readings are expected on Saturday which will exacerbate
existing severe fire weather conditions due to gusty north winds
and low humidities. The areas of greatest concern will be located
in higher terrain of northern and eastern Napa and Sonoma county
as well as throughout the Diablo Range. Any fire starts may spread
rapidly in these conditions. Avoid activities that may lead to
fire ignition, including lawn work, driving on grass, tossing
cigarettes, lighting campfire or fireworks, especially during
Saturday and Sunday afternoons.
