...A major storm system will affect Southwest California tonight 
through Saturday resulting in flooding concerns...

The first in a series of storms is expected to bring light to 
moderate rainfall initially to San Luis Obispo and Santa Barbara 
Counties this morning, before overspreading Ventura and Los 
Angeles Counties this evening through the overnight hours. A 
second more powerful storm system will begin to intensify as it 
approaches Southern California as early as Friday morning. A long 
narrow band of subtropical moisture, otherwise known as an 
Atmospheric River will take aim at Southwestern California. Santa 
Barbara, Ventura and Los Angeles Counties should take the brunt of
this powerful storm Friday morning through Saturday morning. 
Between 2 to 6 inches of rainfall is expected across coast and 
valleys, with between 5 to 10 inches across the Santa Ynez Range,
as well as the Ventura and Los Angeles County Mountains.

Rainfall rates are expected to reach one inch per hour. With this 
storm system expected to be slow in moving through the forecast 
area, there will be several potential hydrological impacts. The 
potential for widespread flooding and flash flooding is a definite 
threat. Not just for the recent burn areas, but anywhere there is 
the potential for flooding. 

The expected high rainfall amounts and intensities could bring 
numerous hydrological impacts. Many rivers and streams could see 
significant flows on Friday into Saturday...but main-stem river 
flooding is not expected at this time. There is a potential for 
swift water rescues due to the heavy rain and resulting increased 
flow rates. There will be the threat of flash flooding with mud and 
debris flows in and around the recent burn areas, especially with 
Friday's storm. Also, widespread and significant urban and small 
stream flooding can be expected at times through Monday. Lastly rock 
and mudslides will be a significant threat during this period, 
especially across canyon roads.

Models are indicating a few more weaker storm systems to move 
through the region into early next week. Any additional rainfall 
could continue to bring hydrological impacts. 

Watch for updates and possible watches and warnings at as we get closer to the event.
