Global Affairs Canada says thousands of Canadians are in the path of extreme weather expected to hit the U.S. and Southeast Asia.
It says 149 Canadians have registered in areas that tropical storm Isaac could affect.
Global Affairs noted that registration is voluntary, so the numbers are only estimates.
The department says it is ready to provide consular assistance to Canadians if required, and travel to the U.S. east coast should be avoided, especially from Edisto Beach in South Carolina to Duck, N.C.
