bring additional showers on Wednesday... mainly on north facing
slopes. There is a slight chance of thunderstorms this afternoon
and tonight.
* Main impact: moderate to heavy snow accumulations generally
between 6 and 12 inches are expected over much of the mountains.
Local amounts up to 16 inches will be possible across the higher
elevations of the san Gabriels. Snow levels will start out
between 4500 and 5000 feet today... then will lower to between
3000 and 4000 feet tonight. There is a chance that snow could
fall as low as 2500 feet late tonight and early Wednesday.
* Other impacts: with the low snow levels... the Interstate 5
corridor near the Grapevine and the Highway 14 corridor through
Soledad Canyon will likely be impacted. In addition... southwest
winds between 15 and 25 mph with local gusts to 35 mph are also
expected to affect the area today. The winds will shift to the
north by late tonight. The combination of moderate to heavy snow
and gusty winds could create blowing snow with reduced
