Sea weather forecast predicts frost

0

With clearer skies and low temperatures that could range between 0 and 4°C, there is a risk of isolated frost in northwestern New Brunswick early Thursday morning and early Friday morning.

A frost warning has been issued for Madawaska County, Restigouche County, Victoria County and Mount Carleton for early Thursday morning. Environment Canada warns: “Frost is expected in places as clear skies and light winds combine with cool temperatures, particularly in low-lying areas.”

If you have temperature-sensitive plants that you can cover or protect, consider doing so if you live in a community under a warning. The risk of frost is higher in low-lying terrain, such as valleys or between hills. Low temperatures are expected to continue to rise over the weekend and into early next week, reducing the risk of frost.

It is not unusual for there to be a risk of frost in northwestern New Brunswick at this time of year. The average climatological last frost dates for this part of the Maritimes range from late May to early June. There have been several years when frosts have continued into June.

Rain on Tuesday

Rainfall on Tuesday was a mixed bag. Relatively widespread rainfall totals of 10 to 30 mm were reported in western New Brunswick and the Atlantic coastal counties of Nova Scotia. Some Nova Scotia communities received 30 to 50 mm in downpours. Parts of eastern New Brunswick, northern mainland Nova Scotia and Prince Edward Island ended up with less than 10 mm of rain.

Fire danger has dropped to low to moderate across much of the Maritimes, according to Natural Resources Canada. The risk is still moderate to high for Prince Edward Island and southeastern New Brunswick, two areas that have not seen as much rain. There is little more than the chance of isolated showers on Friday and the weekend. Dryer air is also expected to move in from the continent during this period. Check daily for provincial or municipal restrictions and guidelines before building an outdoor campfire.
