Description

* WHAT...Hot conditions with high temperatures up to 85 to 90 degrees and up to 95 degrees in the Cascade Valleys, and low temperatures down to 55 to 65 degrees. This will pose a moderate risk of heat-related illness. * WHERE...Portions of northwest and west central Washington. * WHEN...From 10 AM Sunday to 10 PM PDT Monday. * 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. * ADDITIONAL DETAILS...Water temperatures, including area lakes and rivers, remain cold (in the upper 40s and 50s) which significantly increases the risk of cold shock and drowning, even for confident swimmers in calm water. Cold water drains body heat up to 25 times faster than cold air.

Instruction

If planning to head to the water, always wear a life jacket and dress for water temperature, not air temperature. Keep a close eye on children and pets near water. Know the signs of cold shock, such as involuntary gasping and rapid breathing, which drastically increases the risk of drowning. 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. For sheltering information and other human services in your area, dial 2 1 1 during business hours or visit wa211.org anytime.

Description

This is an Early Season Heat Event. What: A period of elevated temperatures is expected. When: Continuing into early next week. Where: The southwestern interior of BC and the western part of the Kootenay District. Remarks: A ridge of high pressure is bringing high temperatures to the region. Temperatures will be warming through the weekend; by Sunday highs are expected to be in the low to mid 30's with overnight lows in the mid teens. High temperatures will persist into early next week. Early season heat can be significant due to the lack of acclimatization to elevated temperatures. Keep your house cool. Block the sun by closing curtains or blinds. Watch for the effects of heat illness: heavy sweating, rash, cramps, fainting, high body temperature and the worsening of some health conditions. Fans alone cannot effectively lower core body temperature, especially for older adults. Use fans to pull in cooler air from outdoors, but if you or someone you care for is experiencing symptoms of heat illness, find a cooler space. ### Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to BCstorm@ec.gc.ca or post reports on X using #BCStorm.
