Alerts: Stephenville, NL

A low pressure system developing off Cape Hatteras this morning will track northeastward today to lie off the coast of Nova Scotia overnight. The low will turn northward on Sunday tracking through the Gulf of St. Lawrence in the morning and across Southeastern Labrador later in the day. 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. High southeasterly winds will accompany this system, with gusts reaching 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 coast and the east coast of the Avalon on Sunday. This could result in minor flooding in low lying coastal areas.
