Humidex values reaching 40 are expected.
Hot and humid conditions are expected today and Sunday.
The maximum daily temperatures today are forecast to reach 30 degrees Celsius or greater. The minimum overnight lows range from 16 to 18 degree Celsius, although this is a couple of degrees lower than the warning criteria of 18 degrees, the day time highs on Sunday will again reach 30 degree Celsius or above, which only gives a very brief relief of the heat on Sunday morning.
Current forecast guidance suggests that the hot and humid conditions could persist into Monday for some areas. A cooler airmass is expected to move into the area by Tuesday.
The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.
Never leave people or pets inside a parked vehicle.
When it’s hot eat cool, light meals.
Keep your house cool. Block the sun by closing curtains or blinds.
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.
