DISCUSSION...
Lighter precipitation will continue into this morning along and
west of the mountains with the greatest coverage and amounts
across San Diego County.

Precipitation may become heavier at times for late this morning
into early this evening with heavier precipitation over northern
Baja extending northward across San Diego County and possible into
western Riverside County. Showers will decrease from the northwest
late tonight and end early Tuesday.

Greatest totals north of the border are expected across southern
and central San Diego County. Through tonight...rainfall across
central and southern San Diego County is expected to range from
around one inch near the coast to 2 to 3 inches in the mountains
with amounts decreasing towards the northwest.

Snow levels near 4000 feet early this morning...will rise to 5000
to 5500 feet for this afternoon...then decrease to 3500 to 4000
feet late tonight.

Urban and small stream flooding is expected across portions of the
coastal...valley...and mountains areas below 5000 feet in San
Diego County with isolated flash flooding possible. The rainfall
could cause a rise in the San Diego River sufficient to flood low
water crossings through Fashion Valley for late this evening
through late tonight.
