A tropical storm warning and wind warning remain in effect for all of Prince Edward Island.
The latest Environment Canada forecast predicts tropical storm force winds of 60 km/h gusting up to 90 km/h can be expected to continue in the province until Sunday morning.
"Very strong wind gusts that may cause damage are expected or occurring," said the weather agency in a statement released Saturday morning.
Post-tropical storm Arthur will move into southwestern Nova Scotia early this morning then track northeastward across the province today.
The strongest winds are expected over southwestern regions where gusts to 120 km/h are possible.
"Damage to buildings, such as to roof shingles and windows, may occur. Gusty winds can damage soft shelters, tents and awnings at outdoor events. High winds may toss loose objects or cause tree branches to break."
Rainfall in the province is expected to end Saturday morning with a 40 per cent of showers afterwards equalling an amount of 5 mm.
Winds are southeast gusting to 50 and forecasted to become east 60 km/h with gusts up to 90 km/h this afternoon.
That wind is expected to shift north late Saturday evening.
Rain is also expected this evening, with an amount of 5 to 10 mm expected Saturday night.
Chris Fogarty, program manager with the the Canadian Hurricane Centre, says the worst of the storm's rainfall will occur early Saturday, with a good two-hour downpour in the morning.
Prince County is expected to receive the worst of the rain.
The strongest winds will occur over the province during Saturday afternoon and evening.
While it won’t be anything like the infamous hurricane Juan in 2003, Fogarty said it will resemble hurricane Earle which hit the Maritimes in 2010.
The storm is hitting on one of the province’s biggest tourism weekends with the Cavendish Beach Music Festival underway today.
Fogarty said Environment Canada is in constant contact with CBMF organizers, with conversations taking place every hour.
Maritime Electric said Friday afternoon that a scheduled power outage for the eastern portion of P.E.I. — from Stratford to the east coast — has been postponed.
