加拿大环境部发出警告,一个低压系统已经在美国德克萨斯州形成,并向东北方向移动,预计周三会影响五大湖地区,这个低压系统还将继续向东北方向行进,给安省、魁省和大西洋省份带来降雨、雨夹雪、冰雨以及夹带冰粒的降雪等等。
环境部说,该天气系统将对GTA地区带来影响,其中影响严重的主要地区在多伦多北面和西面,包括卡列顿 (Caledon)、新市 (Newmarket)、乔治亚娜(Georgina)、约克区北部、以及 Kitchener-Guelph 地区。
降雪-冰雨/大雨-冰粒+降雪
该系统不仅会给多伦多地区带来大雨,而且有至少5厘米的降雪。周三晨间,安省南部会有夹带冰粒的降雪,而随着气温上升,降雪可能转变成冰雨或降雨;而到周四,由于冷空气影响令气温降低,降雨又会变成降雪,因此多伦多北面局部地区或有20厘米的降雪。
680 NEWS 的气象学家泰勒 (Jill Taylor)指出,虽然多伦多没有包括在加拿大环境部的冬季雪暴警告范围内,但也在特别天气声明之下,这也意味着明天多伦多也有雨雪交加的过程,由于飘雪及降雨,市区道路也会相当湿滑,因此司机们一定要小心谨慎地驾车。
泰勒还说,周三周四,估计多伦多会有15-30毫米的降雨,而到周四下午或晚间,多伦多则有5-7厘米的积雪
A major winter storm is expected to affect Ontario Wednesday and Thursday. A low pressure system is expected to develop and emerge from Texas today, then track northeast towards the Lower Great Lakes and intensify into a major winter storm Wednesday. This winter storm is expected to bring significant amounts of rain, snow and ice pellets, along with the possibility of freezing rain. These types of winter storms from Texas typically bring 15 to 30 mm or more of rain to locales that get mainly rain, and 15 to 30 cm of heavy snow to regions that get hit by the heaviest snow. A band of freezing rain and ice pellets often forms over regions near the rain-snow line. Travelling conditions are expected to quickly deteriorate Wednesday as the precipitation arrives. Please refer to weather statements and local forecasts which will be updated with more details as the winter storm evolves and gets closer to the region. Winter storm watches and various warnings may be required as the event draws closer. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to storm.ontario@ec.gc.ca or tweet reports to #ONStorm.
