Expires: 
June 9, 2025 - 4:45am
Description: 
* WHAT...Hot conditions with high temperatures in the mid 80s to near 90 degrees with lower to mid 90s probable in the Cascade Valleys. Lows Monday morning in the mid 50s to lower 60s. This will pose a moderate risk of heat-related illness. * WHERE...Portions of northwest and west central Washington. * WHEN...Until 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.
