NWS Reportedly Moving to Rename Lake Ontario ‘Lake America’ on Weather Maps

The National Weather Service (NWS) is moving forward with a plan to rename Lake Ontario as “Lake America” on its official maps and forecast products, according to a report published by Scientific American.

The publication described the agency as “speeding ahead” with the change, though the full scope, timeline and stated rationale for the renaming were not detailed in the excerpt of the report reviewed.

Lake Ontario is one of the five Great Lakes and forms part of the border between the United States and Canada. Any change to its designation in NWS materials would affect how forecasts, advisories and lake-effect weather warnings referencing the body of water are labeled and communicated to the public.

Scientific American's report focuses on what such a change could mean for weather forecasting, including potential implications for public understanding of alerts tied to the lake, though specific technical or procedural details from the original report were not fully available at the time of this writing.

The National Weather Service has not been reported elsewhere as issuing a separate public statement confirming the change. EGazette could not immediately verify additional details beyond those cited in the Scientific American article.

This report will be updated as more information becomes available.
