Alert: Areal Flood Advisory, Flash Flood Watch

The National Weather Service in Oxnard has issued a

* urban and small stream flood advisory for...
South Los Angeles County in southwestern California...

* until 145 PM PDT

* at 1042 am PDT, Doppler radar and rain gauges indicated moderate
to locally heavy rainfall over much of Los Angeles County.
Rainfall rates are currently between 0.10 and 0.33 inches per
hour, with localized 0.50 inches per hour. Such rain intensities
will generate minor debris flow near recent burn areas impacting
creek beds and roads, especially near the creek burn scar.
Localized Road flooding is also likely, as well Rockslides in
canyon roads. Higher rainfall intensities are possible, which
would lead to significant debris flows near burn areas. Stay tuned
to this developing weather situation.

* Some locations that will experience flooding include...
Los Angeles...
Agoura Hills...
Van Nuys...
Mount Wilson...

Precautionary/preparedness actions...

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

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, urban areas, highways, streets and underpasses as
well as other drainage areas and low lying spots.

Move away from recently burned areas. Life threatening flooding of
creeks, roads and normally dry arroyos is likely. The heavy rains
will likely trigger Rockslides, mudslides and debris flows in steep
terrain, especially in and around these areas.
