Environment Canada has issued a special weather statement warning of large wave activity today and into tonight for the Avalon Peninsula, Clarenville and vicinity, Bonavista Peninsula, Terra Nova, Bonavista North and Bay of Exploits.
The weather office says a combination of a ridge of high pressure over Labrador and a low pressure system over the North Atlantic will produce large waves over northeastern waters today.
These large waves are expected to approach the northeast and east coasts, from Fogo Island to Cape Race, this afternoon and evening.
Environment Canada advises the public to monitor the latest forecasts and warnings at www.weatheroffice.gc.ca.
There's also a wind warning in effect for the southern half of Southwestern Grand Banks.
Environment Canada says winds will be northeast 20 knots veering to east 25 knots (about 37 to 46 kms/h) this afternoon then increasing to east 35 knots (about 65 kms/h) Friday morning.
In this area, seas are expected to be three to five metres today, building to five to seven metres Friday morning.
