...FIRE WEATHER WATCH IN EFFECT LATE THURSDAY NIGHT INTO SATURDAY
FOR PORTIONS OF SOUTHWEST CALIFORNIA DUE TO GUSTY NORTH WINDS,
HOT TEMPERATURES, AND VERY LOW HUMIDITIES...
.A significant heat wave is expected to affect Southwest
California Thursday through Sunday. The peak of the heat wave
will be Friday and Saturday when widespread record breaking
triple digit heat is expected. This heat in combination with
single digit humidities and gusty north winds will bring the
potential for critical fire weather conditions across the
mountains, Santa Barbara south coast, Santa Clarita Valley, and
Santa Monica mountain. In addition, the extreme heat will create
an unstable air mass that will be capable of producing large
vertical plume growth with any new fire ignitions, especially in
the mountains and foothills.
...FIRE WEATHER WATCH REMAINS IN EFFECT FROM LATE THURSDAY NIGHT
THROUGH SATURDAY AFTERNOON FOR GUSTY NORTH WINDS, HOT
TEMPERATURES, AND VERY LOW RELATIVE HUMIDITY FOR THE MOUNTAINS OF
LOS ANGELES AND VENTURA COUNTIES...
* Winds...Areas of north winds 20 to 30 mph with gusts to 45 mph,
strongest through the Interstate 5 corridor. Peak winds
expected Friday morning into Saturday morning.
* Relative Humidity...Minimum humidities 3 to 10 percent on
Friday, increasing to 7 to 15 percent on Saturday. Very poor
humidity recovery Friday night.
* Temperatures...Highs 95 to 107 degrees across lower elevations
on Friday and Saturday. Lows Friday night in the 80s across
the foothills and lower mountains.
* Thunderstorms...There is a slight chance of thunderstorms with
isolated dry lightning strikes across the eastern San Gabriels
late Saturday afternoon. Any storms that develop will be
capable of producing gusty and erratic winds.
* Impacts...If fire ignition occurs, there could be rapid
wildfire spread and large vertical plume growth that would
lead to a threat to life and property.
