This Hazardous Weather Outlook is for portions of western Upper
Michigan and central Upper Michigan.

.DAY ONE...Tonight

Wave heights will build as high as 8 to 12 feet late tonight
along the western shoreline of the Keweenaw and areas to the
southwest. This may lead to minor beach erosion.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

If surface temperatures become cold enough, freezing rain with
some ice accumulation would be likely over far western Upper
Michigan Wednesday evening into Thursday morning as a low
pressure system tracks across the Upper Great Lakes. If enough
cold air moves in on Thursday, the mixed precipitation could
change to snow into Thursday evening. The greatest chances for
snow accumulation would be over far western Upper Michigan.

Due to the wet conditions over the last couple weeks, if heavy
rain occurs Wednesday into Thursday there will be elevated stream
and river levels. Heavy rain will also result in ponding of water
on roads and in other low-lying and poor drainage areas. Be aware
of standing water on roads, especially at night.
