Potential for moderate to heavy snowshower activity continues on the
north and central coasts. Further south, flurry activity is less

slide down the coast from the northern gulf of Alaska reaching the
north coast Monday afternoon and the south coast Tuesday afternoon.
Moderate to heavy snowfalls will accompany this system and all
coastal ranges will be affected. Dry arctic outflow conditions
will develop in the wake of the second low over the north and
