The heat warning was ended on July 6th at 8:00am.
Environment Canada has issued a heat WARNING for Hamilton this afternoon. A heat warning is issued if two or more consecutive days are forecast with daytime highs greater than or equal to 31°C and nighttime lows greater than or equal to 20°C or a Humidex of 40°C or greater.
Hot and humid conditions begin tomorrow.
Beginning Friday and continuing through the Canada Day long weekend, daytime highs are expected to reach the low to mid thirties with humidex values into the mid forties. Overnight low temperatures will only fall to the low to mid twenties, except high teens in some rural areas, providing little or no relief from the heat.
Watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.
Drink plenty of water even before you feel thirsty and stay in a cool place.
Seek a cool place such as a tree-shaded area, swimming pool, shower or bath, or air-conditioned spot like a public building.
Never leave people or pets inside a parked vehicle.
