The Pacific Northwest is bracing for a significant heat wave, with excessive temperatures forecasted to affect major cities including Portland and Seattle this weekend. The National Weather Service has issued extreme heat warnings across the region, with Portland potentially reaching triple digits and Seattle anticipating its first 90-degree day of the year. Local authorities have activated cooling centers and are deploying response units to assist residents as heat advisories remain in effect. As thousands gather for the World Cup matches in Seattle, officials are urging precautions against heat-related emergencies. With temperatures climbing into the upper 90s, this heat wave marks the arrival of the first significant warm spell of the summer season, posing risks particularly for vulnerable populations.
