* WHAT...Hot conditions with high temperatures in the 90s expected and low temperatures in the 60s. This will pose a moderate heat risk of heat-related illness. * WHERE...Portions of northwest and west central Washington. * WHEN...From 2 PM Sunday to 10 PM PDT Tuesday. * IMPACTS...Heat will significantly increase the risk of heat-related illnesses for those who are sensitive to heat, especially those without effective cooling or adequate hydration.

Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances. Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 9 1 1.

Service Notice – June 2025: The Environment and Climate Change Canada (ECCC) CAP Service undergoes changes from time to time as the business of alerting evolves. For 2025, changes are expected to include... 1) ECCC's initiative to upgrade the presentation of alerts into Colour-Coded Weather Alerts is planned for deployment for later in 2025. Data changes will appear in CAP-CP upon this deployment, 2) SAME event codes for a few alert types are updated and 3) other minor improvements and corrections.

Temperatures reaching 30 degrees Celsius combined with overnight lows near 16 degrees Celsius are expected for the next 2 days. This is a heat warning. Temperatures are very high and there is a moderate risk to public health. Maximum temperatures near 30 degrees C. Where: Howe Sound, Whistler, Pemberton, East Vancouver Island and Inland Vancouver Island. When: Maximum temperatures are expected to reach or possibly exceed 30 degrees Celsius on Sunday and Monday, with overnight lows expected to remain above 16 degrees Celsius. Maximum temperatures above 30 degrees are likely on Tuesday as well, followed by a cooling trend on Wednesday. ### Heat affects everyone, but the risks are greater for: seniors, people who live alone, people with pre-existing health conditions such as diabetes, heart disease or respiratory disease, people with mental illness such as schizophrenia, depression, or anxiety, people with substance use disorders, people with limited mobility. Check on family, friends and neighbours, who are at higher risk, particularly if they live alone, to make sure they have a cool space.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
