A low pressure system over the East Coast of the United States will intensify as it moves across the Maritimes on Thursday to lie over the Gulf of St. Lawrence by Thursday evening. Snow will develop over most regions overnight tonight ahead of this system. For the Great Northern Peninsula: snow will begin early Thursday morning and then change to ice pellets or freezing rain in the afternoon. Generally 15 centimetres of snowfall is anticipated followed by potentially significant amounts of freezing precipitation. The precipitation will taper off or end Thursday night. For regions under a freezing rain warning: snow will begin overnight tonight and then change through ice pellets to freezing rain in the morning. Freezing rain may persist for several hours, especially in low-lying valley locations, before temperatures rise above zero allowing the precipitation to change to rain. For southern coastal regions including the Southern Avalon: snow will change through freezing rain to rain at times heavy by Thursday morning. Total rainfall amounts in excess of 30 millimetres can be expected across these regions before tapering off Thursday night, with amounts over 60 millimetres possible from Burgeo to the Connaigre Peninsula. Warm temperatures combined with these rainfall amounts will lead to significant snow melt, creating a potential for localized flooding. Additionally, strong south to southeasterly winds ahead of this system will spread across the island during the day on Thursday. Winds in the Wreckhouse area are expected to begin gusting over 100 km/h near dawn on Thursday and then persist until Thursday evening. The highest gusts, reaching 130 km/h at times, are expected to affect the area during the morning hours on Thursday. Furthermore coastal gusts are forecast to reach 100 km/h along parts of the East Coast from Bonavista North to St. John's Thursday afternoon.
