.A significant heatwave is on the way for late this week into this
weekend, bringing dangerous fire-weather conditions.

producing unseasonably unstable conditions.
* RELATIVE HUMIDITY...Minimum relative humidity 8-20 percent,
lowest Wednesday and Thursday.
* THUNDERSTORMS...Isolated thunderstorms will be possible Friday
through the weekend, and accompanying lightning strikes will
be capable of starting new fires on the peripheries of rain
cores.
* WINDS...Southwest at 10-20 mph gusting to 20-25 mph over the
western Antelope Valley Foothills and vicinity and in other
wind-favored areas such as through passes and canyons. Lighter

wind- shifts and increased fire-spread rates, even from distant
thunderstorms.
* IMPACTS...If fire ignition occurs, conditions are favorable
for extreme fire behavior and rapid fire growth, which could
threaten life and property. Be aware of sudden re-direction of
fires in response to passing outflow boundaries.
* ADDITIONAL DETAILS...Fire-weather headlines may eventually
need to be extended into Sunday.
A Red Flag Warning means that fire-weather conditions are
expected to be favorable for the development of extreme fire
behavior. Use extreme caution with anything that can spark a
wildfire. Residents near wildland interfaces should be prepared to
evacuate if a wildfire breaks out. See readyforwildfire.org and
