KITCHENER -- Some expected heat and humidity in Waterloo Region and Wellington County has caused Environment Canada to issue a special weather statement for the area.

Maximum temperatures ranging from 30 to 33 degrees Celsius are expected on Tuesday, with an overnight low of 20 C, followed by cooler temperatures on Wednesday.

The agency says these conditions pose a health risk, especially for seniors, young children, and those with chronic illnesses.

Residents are advised to drink cool liquids before feeling thirsty, dress appropriately for the weather, and spending a few hours in a cool place.

Some splash pads are open after the province reversed the pandemic-related closures over the weekend. However, some parks and cooling centres are closed due to COVID-19.

Anyone going to a splash pad is reminded to following public health guidelines, maintain proper physical distancing and wash or sanitize hands often.

The special weather statement has also been issued for Huron-Perth, Dunnville-Caledonia-Haldimand, Oxford-Brant, and Simcoe-Delhi-Norfolk.
