A deepening low pressure system just southwest of Nova Scotia will track northeastward across Central Newfoundland tonight. Snow and blowing snow associated with this system will develop over Southwestern Newfoundland near noon and spread to the remainder of the island by this evening. For regions under a winter storm warning, snowfall accumulations will range between 15 centimetres for eastern areas to near 40 centimetres for western regions by Thursday morning. In addition, strong southeasterly winds gusting up to 100 km/h will develop ahead of the storm and shift to strong northwesterly winds gusting up to 110 km/h overnight. The fresh snowfall and strong winds will cause poor visibilities in blowing snow. For regions under wind warnings strong southeasterly winds will develop early this evening ahead of this system with gusts up to 100 km/h expected along the South Coast and gusts to 130 km/h in the Wreckhouse area. Winds will switch to westerly overnight with gusts ranging from 110 km/h along the South Coast to 130 km/h for the Southern Avalon. The extreme wind speeds expected over the next 36 hours for the South Coast and Avalon Peninsula are not unheard of for Newfoundland however they are potentially damaging so it would be adviseable to take appropriate precautions. Higher than normal water levels are expected during the high tide Thursday morning between Green Bay and Cape Freels so minor coastal flooding is possible. However damage to coastal infrastructure is not expected at this time. Please refer to the latest public forecasts and special weather statement for further details.
