The first heat wave of the season is unseasonable late, but it is due to arrive in Kamloops on Saturday — and it has brought with it a special weather statement from Environment Canada.
Beginning this weekend, a strong ridge of high pressure will build over Kamloops and the Southern Interior, with the mercury expected to shoot up into the 30s.
A high of 29 C on Saturday will become highs of 33 on Sunday and 36 on Monday, Tuesday and Wednesday before dipping to a relatively tepid 34 by Thursday as the ridge of high pressure breaks down.
Overnight lows during that stretch will only dip into the mid-teens and possibly nudge the 20 C mark, which Environment Canada said can lead to an increase in heat-related illnesses.
The public is advised to take measures to prevent overheating:
• Stay cool and hydrated, particularly during the hottest period of the day, which is from 1 p.m. to 5 p.m.;
• Limit outdoor activity during the day to early morning and evening.
• Dress for the weather by wearing loose, lightweight clothing. Protect yourself from the sun by wearing a wide-brimmed hat and sunglasses.
• Keep your home cool. Open windows, close shades or blinds, use an air conditioner and prepare meals that do not require an oven.
• Never leave children or pets alone in a parked car.
Environment Canada said the special weather advisory may be expanded to heat warnings for some Southern Interior regions Environment Canada issues heat warnings for the Southern Interior when the agency expects two consecutive days of maximums of 35 C or higher with an overnight minimum of 18 C or higher.
