The upcoming finale of August promises to be a damp affair.
The high pressure that has been responsible for the pleasant weather of the past week is forecasted to move east of the Maritimes by Friday. This will pave the way for a wide-reaching area of low pressure and an assortment of weather fronts to make their way in from the west. We can anticipate unfavourable weather, including rain, showers, and strong winds throughout the Maritimes, particularly on Saturday. In certain regions, rainfalls could be intense.
As the high pressure system shifts east over the weekend, low pressure fronts from the west will usher in potentially heavy rains. Predicted rainfalls for the duration of the weekend range from 20 to 50 mm. However, certain weather forecast models suggest that isolated patches could experience between 50 to 100 mm within that rain. Regions at a higher risk of torrential rain include western Nova Scotia, southern New Brunswick, and Prince Edward Island. The window of risk extends from Saturday morning through to Sunday morning for affected regions.
A Special Weather Statement has been issued by Environment Canada for western areas of southern New Brunswick, Nova Scotia, and Prince Edward Island, addressing the potential for heavier rain.
Rainfall should commence across the region on Saturday, with a possibility of it being heavy at times in western Nova Scotia, southern New Brunswick, and Prince Edward Island. Rain totals exceeding 50 mm within a 24 hour period introduces an elevated risk of flooding. Sudden downpours can create hazardous conditions on the roads, including impaired visibility and hydroplaning.
Accompanying the rain on Saturday will be southerly winds– consistent speeds of 20 to 30 km/h, with gusts reaching 30 to 60 km/h. The risk of downpours is predicted to persist well into Saturday night.
By Friday, forecasters should be able to identify with more accuracy the regions at a higher risk of heavy rain. Therefore, it is recommended that residents check local forecasts on Friday, and once again on Saturday.
Regular updates will be provided till the end of the week.
