NWS Announces Changes to Marine Zones around the Apostle Islands
The NWS Weather Forecast Office (WFO) in Duluth, MN (DLH) has added one new marine zone to encompass the outer Apostle Islands beyond 5 NM from the mainland.
The zone will extend from the current breakpoint between LSZ146 (Port Wing to Sand Island WI) and LSZ147 (Sand Island to Bayfield WI) out an additional 5 NM from the islands that make up the remaining portion of the Apostle Islands that are located more than 5 NM from the mainland all the way to the midpoint of LSZ148 (5 NM southeast from Madeleine Island) and then return back along the current boundary of LSZ147 (Sand Island to Bayfield WI).
This change will remove a large portion of the offshore zone LSZ162 (Lake Superior west of a line from Saxon Harbor WI to Grand Portage MN beyond 5NM) and turn it into a near shore zone for which small craft advisories can be issued. Click here for more information.
