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. * ADDITIONAL SOURCES OF INFORMATION: - For information on appropriate preparations see ready.gov - For information on creating an emergency plan see getagameplan.org - For additional disaster preparedness information see redcross.org NEXT UPDATE ----------- As it pertains to this event, this will be the last local statement issued by the National Weather Service regarding the effects of tropical cyclone hazards upon the area. Flood Watches remain in effect however, and continue to monitor weather.gov/LOX for the latest weather information. $$ Rorke
