Advisory

**TROPICAL STORM WARNING FOR ALL OF LOS ANGELES COUNTY...AS WELL AS THE MOUNTAINS AND VALLEYS NOW UNTIL FURTHER NOTICE**

National Weather Service has issued a **TROPICAL STORM WARNING FOR ALL OF LOS ANGELES COUNTY...AS WELL AS THE MOUNTAINS AND VALLEYS NOW UNTIL FURTHER NOTICE**
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible devastating impacts across the eastern San Gabriel Mountains and adjacent foothills of the Antelope Valley. Potential impacts include:
- Major rainfall flooding may prompt many evacuations and rescues.
- Small streams, creeks, canals, arroyos, and normally dry washes may become dangerous rivers. Destructive runoff may rage down mountain valleys while increasing susceptibility to rockslides, mudslides, and debris flows. Flood control systems and barriers may become stressed.
- Streets and parking lots become rivers of moving water with underpasses submerged. Driving conditions become dangerous. Many road and bridge closures with some weakened or washed out.
Protect against life-threatening rainfall flooding having possible extensive impacts across the remainder of Los Angeles and Ventura Counties, and possibly in eastern Santa Barbara County. The most significant flooding is expected over the mountains, foothills, valleys, and urban areas.
* WIND:
Prepare for hazardous wind having possible significant impacts across Los Angeles and Ventura Counties, with greatest impacts over Catalina Island and Santa Barbara Island, as well as the mountains, valleys, and foothills of Los Angeles and Ventura Counties. Some of the strongest winds will impact areas that are normally susceptible to strong northeast winds. Potential impacts in this area include:
- Damage to porches, awnings, carports, sheds, and unanchored mobile homes. Unsecured lightweight objects blown about.
- Many large tree limbs broken off. A few trees uprooted, but with greater numbers in places where trees are shallow rooted. Some fences and roadway signs blown over.
- A few roads impassable from debris, particularly within urban or heavily wooded places. Hazardous driving conditions on bridges and other elevated roadways.
- Scattered power and communications outages.
* TORNADOES:
Little to no impacts are anticipated currently across Los Angeles, Ventura, Santa Barbara, or San Luis Obispo Counties in Southern California.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
Listen to local official for recommended preparedness actions, including possible evacuation. If ordered to evacuate, do so immediately.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to complete all preparations to protect life and property in accordance with your emergency plan. Ensure you are in a safe location before the onset of strong winds or possible flooding.
If heading to a community shelter, become familiar with the shelter rules before arrival, especially if you have special needs or have pets. Take essential items with you from your Emergency Supplies Kit.
Failure to adequately shelter may result in serious injury or loss of life. Always heed the advice of local officials and comply with any orders that are issued. Remember, during the storm 9 1 1 Emergency Services may not be able to immediately respond if conditions are unsafe. This should be a big factor in your decision making.
If you are a visitor, be sure to know the name of the city or town in which you are staying and the name of the county in which it resides.
Listen for these locations in local news updates. Pay attention for instructions from local authorities.
Rapidly rising flood waters are deadly. If you are in a flood-prone area, consider moving to higher ground. Never drive through a flooded roadway. Remember, turn around don`t drown!
If in a place that is vulnerable to high wind, such as near large trees, a manufactured home, upper floors of a high-rise building, or on a boat, consider moving to a safer shelter before the onset of strong winds or flooding.
Closely monitor weather.gov, NOAA Weather radio or local news outlets for official storm information. Be ready to adapt to possible changes to the forecast. Ensure you have multiple ways to receive weather warnings.
