OK Oakvillians, time to make sure your air conditioning is working, because for the next few days a Heat Warning is in effect. Environment Canada issued the warning at 3:51 PM, Monday, July 4, 2016. High humidity with temperatures above 30 degrees is expected to last until Wednesday, July 6, 2016, and may be extended through Thursday, if the forecast of plus 30 degrees holds true.
The hot humid weather will begin to roll in early tomorrow. You'll wake up to a muggy 20 degrees which is going to feel like 25 degrees. Humidex values are going to make temperatures feel like 35 degrees on Tuesday, 36 degrees on Wednesday and, 37 degrees on Thursday. We are looking at a 40 percent chance of rainfall for both Wednesday, and Thursday with thunderstorms likely on Wednesday.
The winds will start off from the West, then move South-West on Wednesday, which depending on the angle will mean cooler temperatures closer to the lake. By Thursday as the wind direction moves east, temperatures will be cooler by Lake Ontario.
Here is the Heat Warning from Environment Canada:
Temperatures for Tuesday and Wednesday are expected to be near or hotter than 31 with an overnight low of 21 providing little relief from the heat during this timeframe.
Current information suggests that this heat episode will mainly affect the Golden Horseshoe area.
While heat can put everyone at risk from heat illnesses, health risks are greatest for
- older adults;
- infants and young children;
- people with chronic illnesses such as breathing difficulties, heart conditions or psychiatric illnesses;
- people who work in the heat;
- people who exercise in the heat;
- homeless people; and
- people without access to air conditioning.
Drink plenty of liquids especially water before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration.
Heat warnings are issued when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.
