BC air quality alerts in effect for North Peace region, Fort Nelson
Environment Canada says smoke from the northern Alberta wildfire is causing poor air quality and reduced visibility in parts of northeast BC
Special air quality alerts are in effect for the North Peace and Fort Nelson region.
The weather service says smoke from wildfires can be harmful and everyone should try to find a place where they can get fresh, clean air.
More than 29,000 Albertans have been ordered out of their homes in recent days due to dozens of wildfires.
Two out-of-control fires are also raging in northeast BC.

BC flood update
Bonaparte River flooding means more evacuation orders for Cache Creek
The risk of flooding has led to more evacuation orders for residents in Cache Creek Village as warmer temperatures rapidly melt into the snowy mountains.
In his latest order, Mayor John Ranta says about two dozen properties must be evacuated due to the immediate danger posed by the flooding of the Bonaparte River.
Cache Creek remains under flood warning.
Last week, the community dealt with rising water from the creek that flowed through its firehouse, flooding several homes and businesses and temporarily closing Highways 1 and 97.
Provincial emergency officials said less rain than expected in the interior south last weekend has stabilized flood risk for a while, but forecasters warn warm weather is likely to trigger snowmelt and other threats later this week. .
The community of Grand Forks, which also declared a local state of emergency last week due to flooding, has begun to lift some of the protections that were in place.
But officials said in an online statement that other protections will remain as they monitor the forecast.

Ways to beat the heat
8 tips to prepare for the heat
As we head into this weekend and summer, preparation is key when it comes to staying cool and preventing heat-related illnesses. Here are some tips for preparing it (you can read our full story with more tips here):
1. Consider installing an air conditioner:Air conditioners become hot ticket items when the hot weather starts, so buy them early before they run low. Alternatively, you can also try the DIY route: How to Make Your Own Air Conditioner for Just a Few Dollars.
2. Prepare your home:When it's hot outside, you want to maximize the cooler temperatures inside. Check the condition of caulking around doors and windows and seal any air leaks. Install or use drapes and blinds to help block out sunlight and reduce indoor heat. Stock up on items like sunscreen, bottled water, sunglasses, sun hats, wading pools, spray bottles, or whatever you need to help you stay cool.
3. Sign up for public heat notices:The heat alerts, which are broadcast via news media, social media, the Environment Canada website and digital weather applications, are intended to notify the public of extreme heat conditions and how long the conditions are expected to last. You can get weather alerts from Environment Canada for freeWeatherCAN app.
4. Find out where to cool off:When a heat wave hits and you don't have air conditioning, it's best to stay outside — but stay indoors. Go to malls, cinemas, cafes and restaurants. Municipalities often issue notices listing available places to cool off, such as swimming pools, spray parks, water fountains and misting stations.
5. Ilumine-se no menu:Skip the heavy foods and opt for salads, sandwiches, fruits and veggies instead. Foods like watermelon and cucumber contain more than 90% water and will keep you hydrated.
6. Keep devices turned off:Avoid using appliances that produce heat, such as a stove, oven, dishwasher, and dryer.
7. Prepare a support place to sleep or work:If you don't have air conditioning or your bedroom feels like an oven, choose a different place to sleep. As the heat rises, the ground floor or basement are usually the coolest places in the house.
8. Know the signs of heat-related illness:Refresh yourself about the signs and symptoms of heat-related illnesses so you can identify problems and seek help.
