A heat episode is expected today and Thursday. High temperatures will be near 30 degrees with overnight lows dropping to near 18 degrees. Humidity will also be a factor with humidex values in the low to mid thirties both days.
The heat episode will come to an end Friday morning with the passage of a cold front.
Heat illnesses are preventable.
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.
Never leave people or pets in your care inside a parked vehicle or in direct sunlight.
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.
