With a ridge of high pressure offshore, moist air is being directed northward, sparing B. C.'s coastline from excessive heat. Temperatures along the coastal regions will stay near seasonal norms due to the moderating effects of onshore flow. However, Interior regions and valleys are expected to see above-seasonal heat Thursday and Friday, coinciding with peak wildfire activity. These conditions could exacerbate wildfire challenges in already hard-hit areas. RELATED: B.

The next fall nor’easter is brewing off the North Carolina coast, setting the stage for extensive impacts throughout the week. The National Hurricane Center is now highlighting this area for potential tropical development, with a 30% chance over the next seven days. WHAT IS A NOR’EASTER? Regardless of tropical development, the Outer Banks are expected to see long-term impacts, including intense wind gusts from the approaching nor’easter, while the storm sits off the coast. The main concern for the Outer Banks region will be intense wind gusts as strong as 40 to 60 mph, fueling moderate coastal flooding and destructive waves. A mandatory evacuation for locals on Hatteras Island is in effect, as storm conditions are expected to worsen, with the potential for significant ocean overwash.

Toronto and Montreal have remained above the freezing mark every day for almost six months. While frosts and even some snowflakes have intruded across parts of Ontario and Quebec in recent weeks, the two cities have yet to reach that magic number. What’s even more remarkable is that a handful of communities across the southern United States have already dipped to the freezing point--and some have even seen accumulating snowfall. DON’T MISS: Official: Canada records first -30°C reading of the seasonThe last time we saw a freezing temperature in either Toronto or Montreal was the second-to-last week of April. Toronto hit -1.3°C early on April 20, while Montreal dipped to -2.0°C the following morning. Our average first frost in both cities occurs right around the middle of October. But warmer-than-normal years can see this milestone slide several weeks past due. Montreal once had to wait 207 consecutive days for its first frost, with the city’s first subfreezing temperature in 2017 waiting until Nov. 7. The latest Toronto’s had to wait to hit the zero-degree mark was Nov. 13, 2022.
