...TWO STORM SYSTEMS THIS WEEK WITH GENERALLY BENEFICIAL RAIN AND GUSTY
WINDS...

...DRY NORTH TO NORTHEAST WINDS FRIDAY NIGHT THROUGH MONDAY...

The first storm system will pass through the region by Wednesday
afternoon. For San Luis Obispo and Santa Barbara Counties, rain
totals of 0.75 to 1.50 inches will be common, with 1.5 to 3.0 inches
in the foothills and mountains. Northwest San Luis Obispo County
will likely see much higher totals. Peak rain rates should range
between 0.25 to  0.50 inches per hour, with local rates of 0.50 to
0.75 inches per hour. For Los Angeles and Ventura Counties, totals
of 0.25 to 0.75 inches will be common, with 0.75 to 1.50 inches in
the favored hills including the Palisades and Eaton burn scars. Peak
rates of 0.10 to 0.25 inches per hour will be common, with local
rates of 0.25 to 0.50 inches per hour. Thunderstorm chances are very
small. Snow levels are very high. Impacts should be generally
minimal, but there will be a few potential problem  areas. There is
a low but present risk of small creek flooding in and  downstream of
the Santa Lucias. Vulnerable canyon roads like Topanga  Canyon will
likely see mud and debris flows. South to southwest wind  gusts of
25 to 45 mph will be common over the mountains, interior, and
Central Coast through tonight, with local gusts of 50 to 60 mph.
After a break Wednesday afternoon through Thursday morning, a second
storm will move through Thursday Night into Friday. This storm will
be the weakest of the two, and bring more uniform rain over the
region. Totals will  generally fall between 0.25 and 1.00 inches,
except 1 to 2 inches over  the favored mountains and hills. Impacts
will again be generally minor.

Winds will quickly turn northwesterly Friday afternoon, then turn
north to northeasterly Friday Night through Monday. Gusts of 30 to
50 mph are likely in the wind favored areas like the I-5 Corridor,
the Santa Monica Mountains, much of Santa Barbara County, and the
Santa Lucia Range. Areas less prone to these winds, like the San
Gabriel Valley, should not see significant winds. Humidities will
lower quickly as well, with  minimums falling into the 10 to
20 percent range by Sunday, especially  in the mountains. While the
combination of winds and humidities may  approach brief critical
conditions, the very recent rains should limit  any fire weather
danger.

Please note: the LAL has been removed nationally and any
thunderstorm  chances will still be mentioned in the weather
element.
