SITUATION OVERVIEW
------------------

Former Tropical Storm Hilary has weakened and become post-tropical. 
While the winds associated with this system have gone below tropical 
storm strength, prompting the warning cancelation, the threat for 
flooding rains will continue into Monday morning over Los Angeles 
and Ventura Counties. Locally gusty winds will also continue. 
Activity will decrease through the day on Monday and into the 
overnight hours.

POTENTIAL IMPACTS
-----------------

* FLOODING RAIN: Additional impacts from flooding rain are still a 
  concern through Monday morning across Los Angeles and Ventura 
  County, especially in and around the mountains. Remain well 
  guarded against dangerous flooding and stay off the roads and away 
  from creeks and washes.

* WIND: Wind gusts up to 25 to 35 mph will continue in some areas, 
  especially in the mountains through Monday morning, which can 
  cause power outages, road hazards, and blow over loose objects.

* SURGE: Little to no impacts are anticipated at this time across 
  Southwest California.


* TORNADOES: Little to no impacts are anticipated at this time 
  across Southwest California.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS: RECOVERY PHASE - Do not enter evacuated areas until 
  officials have given the all clear to return.

* OTHER PREPAREDNESS INFORMATION: Remain off roads unless absolutely 
  necessary, especially in the mountains and deserts. Be alert for 
  flooded roads which could be compromised or littered with debris. 
  Avoid travel until water levels subside and roads have been 
  cleared. Do not drive through places where flood waters cover the 
  road. Turn around, don't drown!

Do not attempt to return to evacuated areas until local authorities 
have inspected roads and bridges and have given the all clear. 
Hazards like downed power lines and trees, washed out roads, 
continued flooding in low lying areas and non-functioning traffic 
lights make travel difficult. 

Do not go sightseeing within impacted communities. Sightseers 
interfere with the emergency work of first responders.
