…RED FLAG WARNINGS IN EFFECT UNTIL 6 AM SATURDAY FOR THE
INTERSTATE 5 CORRIDOR, VENTURA COUNTY MOUNTAINS, SANTA BARBARA
COUNTY MOUNTAINS, SOUTHWEST SANTA BARBARA COAST, INTERIOR SAN LUIS
OBISPO COUNTY, AND CUYAMA VALLEY DUE TO GUSTY NORTHWEST TO
NORTH WINDS, LOW HUMIDITY, AND VERY HOT TEMPERATURES LEADING
TO LARGE VERTICAL PLUME GROWTH POTENTIAL…

.An extremely long-duration heat wave will bring very hot and dry
conditions to southwest California well into next week, hottest
today and Saturday in most areas. The hot and dry conditions will
coincide with northwest to northeast winds, gusting from 25 to 45
mph, today through tonight across many mountain and interior
areas, as well as southwest Santa Barbara County. The very hot
temperatures in the Red Flag Warning area will also bring
a significant threat of large vertical plume growth with any
new fires. While classic Red Flag duration thresholds will
likely not be met, considering the extreme nature of this heat
event and the holiday fire ignition sources available, conditions
are favorable for rapid and large fire growth, along with extreme
fire behavior.

Onshore flow will likely be on the increase Saturday through
Monday, which may lead to increasing southwest to west winds
across portions of the interior and possible Red Flag Warning
extensions in some areas.

* WINDS…North to northeast winds gusting to 20 to 35 mph.

* RELATIVE HUMIDITY…Minimum relative humidity 6 to 12 percent
with poor to moderate overnight recovery.

* IMPACTS…If fire ignition occurs, conditions are favorable for
rapid fire spread and extreme fire behavior which would
threaten life and property.
