Environment and Climate Change Canada has issued frost advisories for all three Maritime provinces.
The advisories are valid and in effect for Wednesday overnight into early Thursday morning.
The weather agency cautions that a patchy frost could develop in frost-prone areas. Those areas are typically inland of the coast and include spots such as hilltops, valleys, and open fields.
Frost advisory
Frost advisories are in effect for the Maritimes Wednesday night into early Thursday morning.
Low temperatures could fall to near two degrees. That temperature is measured at a height of about five feet, but the chilliest nighttime air settles closer to the surface. An air temperature forecast of two degrees means the near-surface air could drop to freezing, creating the risk of frost development.
This is not expected to be a widespread hard frost for the region. That said, if you have temperature-sensitive plants that could be brought inside or covered up you may wish to do so. Varieties of plants that are at risk of damage from a patchy frost include tender annuals (peppers), perennials (hydrangeas), and tropical (palms) varieties.
Frost risk
Areas highlighted in blue have a higher chance of patchy frost developing Wednesday overnight.
Much of the region is already past the average date of last frost. By nature of that being an average, though, it does mean frost has occurred later than May 21 in previous years.
The risk of frost in the region will be reduced Thursday night by increasing cloudiness in the forecast. Low temperatures on the weekend and next week also look high enough to prevent a risk of frost as well.

Wildfire evacuee numbers climb to more than 17,000 in Manitoba, premier says
Social Sharing The number of wildfire evacuees in Manitoba has increased, with more likely as a handful of communities remain on alert. "The numbers have continued to grow. We were saying 17,000. I think we can safely assume it's north of that number now," Premier Wab Kinew said on CBC Manitoba's Information Radio on Thursday morning. He didn't have an estimate on the total but said about 16,800 people are now registered with the Canadian Red Cross. "And keep in mind, not everyone registers with us. Some folks, they just make the decision they're going to stay with family," Kinew said. It's been eight days since he declared a provincewide state of emergency due to rapidly spreading wildfires and extreme fire conditions in northern and eastern Manitoba. Since then, the northwestern part of the province has also become a danger zone. There are 15 communities under mandatory evacuation orders and another three under voluntary evacuation. Three others — Snow Lake, Norway House and Chemawawin Cree Nation (Easterville) — are under evacuation alerts or notices, with people ordered to be ready to leave with short notice. "We are in a new reality when it comes to wildfires. Typically, we would have one part of the province dealing with challenges and … there'd be, like, maybe two communities on evacuation in other summers. This year, it's every region at the same time," Kinew said. "So that's one thing that we need to plan for in the future." The pace at which everything has been happening has also opened an unfortunate door to misinformation on social media, Kinew said. To combat that, the province is launching a digital information portal later on Thursday. "It is striking during a state of emergency how quickly false claims can make their way around social media that actually pull away time and resources from people who would otherwise be co-ordinating an evacuation effort or responding to the actual wildfires themselves," Kinew said. Watch as the northern Manitoba wildfires grow 20 hours ago Duration 1:11 Wildfires have been burning in northern Manitoba since late May, when a province-wide emergency was declared. Watch as CBC Weather Specialist Riley Laychuk tracks the fires threatening the communities of Flin Flon, Sherridon and Pukatawagan. Three days after last week's evacuation of the city of Flin Flon, rumours sprouted on social media about firefighters being killed while battling the blaze. "I realize people are driven by stress in some cases, and in other cases by a compassionate response to try and get information out there, but … to have the added stress of some false information being shared on social media was counterproductive," Kinew said. The province's info portal "will be a trusted source of information on fires, where to find evacuation supports, how [people] can help in the response," he said. The province will also begin holding regular, but not necessarily daily, news briefings. The first of those is scheduled for 12:45 p.m. Thursday. As of Wednesday (the most recent data available), a total of 513,803 hectares had burned in the province. Last year at this time, 43,141 hectares had been impacted. Manitoba's fire situation report shows there are 27 active wildfires and a total of 111 fires to date, which is well above the average of 91 for this time of year. Kinew on Thursday also defended the province's decision to send evacuees to Ontario, addressing criticisms that suggested Manitoba was unprepared to respond to the demand. "That is the Manitoba response, just to be clear," he said. The province hired a private firm to manage the evacuee response, "and they found rooms in Niagara." "Earlier in this same wildfire season, Ontario didn't have rooms and we housed more than 1,000 Ontario evacuees here. I think one of the things that we're seeing this year is that we have to have a pan-provincial — a national — response, just given the scale of the emergency we're facing." The ability to get people, within a week, out of harm's way and into shelters and provide wraparound supports is a testament to the emergency management team in Manitoba and partners like Manitoba Keewatinowi Okimakanak, the Manitoba Métis Federation and municipal leaders across northern Manitoba, Kinew said. One of the other challenges the province has had to address is ensuring thousands of evacuees, especially those in major centres like Winnipeg, are kept safe from exploitation. "It is one of the very disturbing things about this, that even in the midst of the vast, vast majority of Manitobans stepping up and donating or volunteering, that there is a small group of people who are also trying to show up and prey on evacuees," Kinew said. "You can let your mind wander to some of the really bad behaviours that this might encompass." To counter that, security guards and other resources have been installed around evacuation centres, and police are working with First Nations safety officers, he said. "If there's a criminal act going on, there's going to be accountability. Somebody's going to get arrested," Kinew said. And then there's what he calls "a fourth layer of response," meaning help from community groups in Winnipeg like the Downtown Community Safety Partnership, the Bear Clan and Ogijiita Pimatiswin Kinamatwin (OPK), an Indigenous-led organization that supports at-risk youth affected by gangs, poverty and violence. "We've been working with them to ensure that they're, in some cases, that insulating security layer around people to protect them from bad actors," Kinew said. "In other cases, this is about somebody struggling, and we do have crisis stabilization unit, public health nurses and, you know, the medical professionals at each of these shelter sites and reception centres." Mandatory evacuations are in place for: Bakers Narrows. Big Island Lake. Bissett. Cranberry Portage. Flin Flon. Little Athapapuskow cottage area. Lynn Lake. Marcel Colomb First Nation (Black Sturgeon). Nopiming Provincial Park. Parts of Whiteshell Provincial Park. Pimicikamak Cree Nation (Cross Lake). Pukatawagan (Mathias Colomb Cree Nation). Schist Lake. Sherridon. Tataskweyak Cree Nation (Split Lake). Voluntary evacuation orders are in place for: Opaskwayak Cree Nation. Snow Lake. Wanless. Are you an evacuee who needs assistance?

Regina gives away 1,000 seedlings, living up to its ‘tree city' title
Wednesday morning in Victoria Park was a day of giving for the City of Regina, as 1,000 seedling trees were given to the public. The tree of choice this time around was known as Adam's Elderberry. 'It is nice and flowery in the springtime for your backyards,' said Veronica Schroder, who is the coordinator of forestry, pest and horticulture at the City of Regina. 'It [the elderberry] will fruit in the mid to late summer and then you'll be able to use the fruit for jams and jellies and other preserves such as that.' For six years Regina has been marked as a 'Tree City of the World,' which are cities that meet core standards in urban planning. Regina is one of 210 cities internationally and 21 across Canada with the distinct title. Despite not being in a natural green zone, the city is doing what it can to make sure citizens live in a city with more than 500,000 trees as part of a 'prairie landscape.' The city hopes to be a 100 per cent renewable community by 2050. 'Regina has a very specific climate,' said Schroder. 'It's very harsh, it has really cold winters and has very extreme heat in the summer at times. So, we have a limited plant palette of what will actually grow.' The city said there will likely be another tree giveaway on Sept. 24, which also happens to be National Tree Day.
