Officials in St. John's say some areas of the city could see some flooding Thursday as post-tropical storm Rafael blows past Newfoundland.
The Canadian Hurricane Centre says its radar imagery shows Rafael's heaviest rainfall will stay east of the Avalon Peninsula.
The storm will produce waves reaching 10 to 12 metres south of the storm and that could produce some pounding surf along the south coast of Newfoundland.
There is no threat of damaging wind on land, but gale to storm force winds are forecast this morning over southeastern marine areas.
A special marine watch is in effect for strong currents and rapidly changing water levels for portions of southeastern coastal Newfoundland.
Rafael was about 435 kilometres southwest of Cape Race and moving northeast at 74 kilometres an hour with maximum sustained winds of 120 kilometres per hour.
