A low pressure system currently off Cape Hatteras will track northeastward today to lie over the Gulf of St. Lawrence by Sunday morning before moving to lie across Southeastern Labrador later on Sunday. This system will be accompanied by high winds and heavy rains which will develop later today over Southwestern Newfoundland and spread elsewhere tonight. Rainfall accumulations will be highest along the south coast where 40 to 65 millimetres are expected. Parts of Eastern Newfoundland and the Northern Peninsula will see closer to 30 millimetres. The strong southeasterly winds are expected to gust 100 to 120 km/h for most coastal regions of Newfoundland beginning late overnight or Sunday morning. In the Wreckhouse area, southeasterly winds will gust to 160 km/h beginning late overnight before diminishing by mid-morning as winds veer to southerly. Additionally, high waves and pounding surf will impact the south and the east coast of the Avalon on Sunday evening. This could result in minor flooding in low lying coastal areas for areas exposed to the southeast.
