Post-tropical storm Cristobal will not come near Newfoundland today, but was already making conditions wet and wild in eastern Newfoundland. 

The storm, which was downgraded from hurricane status and is racing across the Grand Banks south of Newfoundland, is teaming up with a cold front to dump plenty of rain over the eastern half of the island. 

Environment Canada issued a special weather statement for eastern Newfoundland, warning that Cristobal's "rapid forward speed ... may trigger rapid tide-like changes in harbour water levels." 

The statement said previous tropical storms have caused harbour water levels to rise or fall by as much as two or three metres, or up to 10 feet. 

Heavy rain overnight is expected to continue through Friday. 

Meteorologists warned that some areas on the Burin and Bonavista peninsulas could receive as much as 50 or even 75 mm of rain before the system passes through. 

Cristobal will pack sustained winds as high as 140 km/h, but will be far enough offshore for those winds to have a less dramatic effect on land. 

Because of low pressure already in the area, the passing storm is expected to create weather that "will be distinctively cooler and fall-like," Environment Canada said.
