air quality
Stagnant winter weather conditions are creating elevated pollution levels. High levels of air pollution are expected this evening. Light winds and stagnating weather conditions are expected to cause increasing levels of fine particles and nitrogen dioxide in the above regions. Moderate to high risk AQHI values are expected throughout the evening. Conditions will be improved early Thursday morning. ### When air pollution levels are high, everyone should limit time outdoors. Consider reducing or rescheduling outdoor sports, activities and events. You may experience mild and common symptoms such as eye, nose and throat irritation, headaches or a mild cough. More serious but less common symptoms include wheezing, chest pains or severe cough. If you think you are having a medical emergency, seek immediate medical assistance. People more likely to be impacted by outdoor air pollution, including people aged 65 and older, pregnant people, infants and young children, people with an existing illness or chronic health condition, and people who work outdoors, should reduce or reschedule strenuous activities outdoors and seek medical attention if experiencing symptoms. For further information visit the website https://www.airqualityontario.com/ or contact the Ontario Ministry of the Environment, Conservation and Parks at 416-314-6666. Visit http://www.airhealth.ca for information on how to reduce your health risk and your personal contribution to pollution levels, as well as for current and forecast AQHI values.

Special Weather Statement
An area of thunderstorms and associated freezing rain is advancing eastward toward western New York this evening. These thunderstorms may affect the Niagara Falls and Buffalo areas by around 11 PM. Surface temperatures will be near or slightly below freezing as they cross the area, so a short period of thunder and freezing rain is possible as they move through the area. This activity will move swiftly to the southeast, so areas in southern Genesee County and Wyoming County could see a period of thunder and freezing rain around midnight. Areas in Livingston County would be affected close to 1 AM. Any areas that are below freezing may see bridges and overpasses quickly ice up. Pay attention to your local temperatures and maintain awareness for rapidly changing driving conditions in these areas.
Winter Weather Advisory
* WHAT...Mixed precipitation expected. Total snow and sleet accumulations of one inch or less. Freezing rain accumulations of a tenth to three tenths of an inch. * WHERE...Niagara, Orleans, Monroe, Wayne, Northern Cayuga, and Genesee Counties. The greatest ice accumulations will likely be across northern portions of Niagara, Orleans, and Monroe counties. * WHEN...Until 1 AM EST Thursday. * IMPACTS...Power outages and tree damage are possible in some areas due to ice accretion. The wintry mix and freezing rain may result in very slick conditions on untreated surfaces. The hazardous conditions will impact the Wednesday evening commute. * ADDITIONAL DETAILS...Ice will more readily accumulate on elevated surfaces. Temperatures near the freezing point combined with the higher mid-February sun angle may help mitigate impacts on area roadways, limiting ice accumulation potential.
freezing rain
Freezing rain to affect the area today. What: Several hours of freezing rain leading to ice build-up. Ice accretion of 2 to 5 mm possible. Easterly winds gusting up to 60 km/h.

Areas closer to Lake Huron may be less affected with temperatures likely rising above the freezing mark. Precipitation will diminish in intensity by this evening, although freezing drizzle may affect the area through the night. ### Roads and walkways will likely become icy and slippery. There is risk of injury due to slips and falls. Please continue to monitor alerts and forecasts issued by Environment Canada.
