ANGELES COUNTY...

At 453 AM PST, Doppler radar and automated rain gauges continued to
indicate moderate to locally heavy rain occurring across the
southeastern portion of the Los Angeles Basin around Long Beach with
a line extending north into the San Gabriel Valley. Also, around the
Malibu and Santa Monica Mountains where rainfall rates between a
quarter to just under a half inch per hour were occurring. There
have been multiple reports of local flooding from CHP affecting some
roadways including large boulders that have fallen onto Malibu
Canyon near the tunnel causing lanes to be closed. Minor mud and
debris flows may occur in the vicinity of the Sand, Fish and
Reservoir Burn Areas. Otherwise, urban and small stream flooding
will occur in the advisory area through early this morning. Driving
conditions could become dangerous across canyons including Malibu,
Topanga and Kanan Rd. due to large boulders and debris falling from
canyon walls this morning.

* Some locations that will experience flooding include...
Long Beach...Malibu...Acton...Rancho Palos Verdes...Whittier...
Burbank...Redondo Beach...Pasadena...Woodland Hills...
Downtown Los Angeles...Palmdale...and Santa Monica.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Be especially cautious at night when it is harder to recognize the
dangers of flooding.

A Flood Advisory means river or stream flows are elevated, or ponding
of water in urban or other areas is occurring or is imminent.
