...ELEVATED FIRE WEATHER CONDITIONS ACROSS THE HIGHER ELEVATIONS
THROUGH THE WEEK DUE TO HOT AND DRY CONDITIONS...

Hot and dry conditions are forecast through Thursday,  which will be
accompanied with weak offshore flow. Poor to very  poor overnight
recovery is expected for the thermal belts,  generally for
elevations above 1000-1500 feet, leading to elevated fire weather
conditions. The marine layer is expected to be  confined to the
immediate coast and around 500 feet. If working in the thermal
belts, Moderate to Extreme HeatRisk is forecast this  week, with
temperature and HeatRisk trends improving late week. A pattern
change is expected late in the week or over the weekend. Cooler
weather and the potential for improved RH recovery is  forecast or
Friday.

Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.

...ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS WITH HIGH RISK
FOR PLUME DOMINATED FIRES AND HEAT ILLNESS THROUGH MUCH OF NEXT
WEEK...

Extremely hot conditions will persist through much of next week.
High temperatures of 95 to 107 degrees, and mixing heights
10,000-14,000 feet, will be common over much of the area, including
the coasts. While winds will generally be light, areas of northeast
to southeast winds of 10 to 20 mph with gusts 20 to 30 mph will
persist each night through  early afternoon hours, especially today
through Monday across LA/Ventura counties. Minimum humidities
between 10 and 20 percent will be common away from the immediate
coast. Due to the lighter winds, Red Flag Warnings are unlikely, but
there is a history of large fires with similar heat and deeper
mixing heights. As such, there is a high risk for plume-dominated
and fast moving fires. Widespread Heat Advisories and Warnings are
in effect through next week, with a high risk for heat-related
illness. A gradual cooling trend is likely Friday through next
weekend, with a small chance of showers and thunderstorms if
remnants of Hurricane Rachel end up streaming into our area.  Minor
to moderate coastal flooding concerns will likely occur Tuesday
through Friday due to southerly swells from Hurricane Rachel.
