Heat Warning continues for Colchester, Cumberland, Hants and Pictou Counties
Environment Canada says very high temperatures and humidity are expected for much of Nova Scotia on Tuesday.
A Heat Warning issued at 4:38 a.m. calls for temperatures approaching 27 to 30 degrees Celsius coupled with humidex values of between 32 and 36 for the next couple of days.
Forecasters say there won't be much respite from the heat overnight, with temperatures staying between the 14 and 16 degree mark.
The weather agency says people should drink plenty of water, even before they feel thirsty and stay in a cool place, while reminding the public that people or pets should never be left inside a parked vehicle.
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.
