...THERE IS A HIGH RISK OF EXCESSIVE RAINFALL FOR PORTIONS OF 
SOUTHERN CALIFORNIA...


...Central to Southern California...
The latest models are in good agreement on the evolution of a 
strengthening cyclone off the central California coast early 
Sunday as this low pushes northward towards the northern 
California coast.  The strong IVT values that begin to impact the 
central California coast late day 1, ~1000 kg/m/s, will persist 
into central California coast range, pushing inland into the 
northern portions of the San Joaquin Valley and Sacramento Valley 
and southward into the Transverse Range.  Strong inflow and 
available instability across the area will allow for 1" an hour 
rain totals, which would be especially problematic where there are 
burn scars.  The probabilities of 8"+ in 24 hours are high enough 
to introduce a High Risk for portions of the southern CA 
Transverse ranges.  General 3 to 5" areal average amounts likely 
in both the Transverse and Central California Coast Ranges, with 
maximum totals just over 10" possible in areas of most persistent 
training and upslope flow.  Modest expansions were made to the 
Slight and Moderate Risk areas.
