319 PM CST Sat Nov 30 2019

This Hazardous Weather Outlook is for portions of northeast
Minnesota and northwest Wisconsin.

.DAY ONE...This afternoon and Tonight

A potentially historic winter storm will pass through the region
through Sunday, bringing heavy accumulating snow, strong east
winds, and the potential for lakeshore flooding. Snowfall rates of
1 to 2 inches per hour will be possible near Lake Superior through
the night. Storm total snowfall between 10 to 20 inches will be
possible, with locally higher amounts near Lake Superior due to
lake enhancement. There will be a sharp snowfall gradient along
the Borderland region with ranges from 1 to 10 inches possible in
a short distance. Strong east winds gusting to 45 mph are expected
along the North Shore which will lead to blizzard conditions. A
Blizzard Warning remains in effect for the Duluth area north along
the North Shore, including Two Harbors and Silver Bay. A Winter
Storm Warning remains in effect for the remaining portions of the
Northland. Strong east winds will transport water into Western
Lake Superior. This will lead to large waves over far western Lake
Superior and combined with the high water levels will likely lead
to lakeshore flooding for the Twin Ports and from Ashland to
Saxon Harbor. A Lakeshore Flood Warning remains in effect through
late Sunday afternoon.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Lakeshore Flood Warnings will continue for the Twin Ports and from
Ashland to Saxon Harbor through Sunday afternoon, and for the
shoreline of Ashland and Iron counties through Sunday evening.

.SPOTTER INFORMATION STATEMENT...

Snow spotters are requested to report their snowfall measurements
to the National Weather Service.

319 PM CST Sat Nov 30 2019

This Hazardous Weather Outlook is for portions of the Nearshore
waters of western Lake Superior.

.DAY ONE...This afternoon and Tonight

Strengthening northeasterly winds will lead to gale-force gusts
of 35 to 45 knots across western Lake Superior. This will support
large waves of 10 to 18 feet or larger along the North Shore.
There could even be some localized storm-force gusts possible
along the far western arm of Lake Superior near the Twin Ports
area.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Gale-force gusts between 35 to 40 knots will continue into
Sunday, particularly along the South Shore of western Lake
Superior. Winds will gradually weaken and turn northerly Sunday
afternoon. While the winds will diminish, waves could remain large
and hazardous to smaller vessels into Sunday evening.
