... The first organized frontal system of the season will bring
heavy rain to southwest Washington and northwest Oregon... and and
gusty coastal winds Tuesday night and Wednesday...
An early fall frontal system will bring a drastic change in
weather tonight and Wednesday. The main weather impact will be
widespread moderate to heavy rain that will begin along the coast
late this afternoon and slowly spread inland tonight and
Rainfall totals from Tuesday through the end of the week are
expected to reach near an inch over the interior lowlands... and 1
to 2 inches for the coast and mountains. This heavy rain may
result in localized urban flooding... especially where the local
wildfires have left burn scars. Roads located below burned slopes
may be at risk for rapidly moving landslides.
Motorists are urged to use caution on the roadways over the next
few days. Given the long period of dry weather that has preceded
this front... residual oil and grease on the Road surfaces will
likely become quite slick at the onset of the rain.
Gusty winds are expected along the coastal beaches and headlands
this afternoon and evening... with gusts up to 55 mph possible.
These winds combined with the heavy rain may result in the Downing
of tree limbs... and possibly localized power outages.
The colder air mass will bring snow levels into the high
Cascades... and some of the higher mountain ski resorts may even
see some snowflakes.
