Canada's national forecaster says the Maritimes could be in the path of a tropical storm that formed off the US coast Sunday morning.
"Swells generated by Chris are expected to increase and affect portions of the coasts of North Carolina and the mid-Atlantic states into early next week", the NHC said, adding that some of the resulting conditions could be life-threatening.
No coastal watches or warnings are in effect, but forecasters say swells along the coasts of North Carolina and the mid-Atlantic states could produce unsafe surf and rip current conditions.
Tropical-storm-force winds extend outward up to 45 miles from the center.
Maria also inflicted significant damage on Guadeloupe, Dominica, and the U.S. Virgin Islands - all places that are expected to be drenched with several inches of rain in the coming days thanks to Beryl.
At that point, a cold front should absorb Chris and rapidly sweep it to the north-northeast toward Nova Scotia and Newfoundland.
'Additional weakening is forecast during the next 48 hours, especially once Beryl reaches the eastern Caribbean Sea on Monday, ' the NHC said. The storm could make landfall as a tropical storm early Friday in far northeastern Canada.
The storm that had been the Atlantic season's first hurricane has been losing power, but residents on islands hit hard by storms a year ago stocked up on food and water Saturday and prepared for possible damaging winds, rains and waves.
McNoldy noted the simultaneous presence of two July tropical storms, Beryl and Chris, hasnt happened since 2011, when Bret and Cindy roamed the Atlantic.
By Tuesday, the storm is forecast to degenerate but could still produce some gusty winds and heavy rain over Puerto Rico and Hispaniola.
Tropical storm watches were in effect for Barbados, St. Lucia and Dominica.
