Slow-Moving ‘Kelvin’ Wave Raises Concerns Over Potential Heat in California

A slow-moving Kelvin wave of planetary scale is moving toward California, prompting concern that it could influence temperatures and weather patterns across the state. Meteorologists say the phenomenon may contribute to persistent high pressure, intensify heat, and increase the risk of dangerous conditions, particularly for vulnerable residents. Forecasters are watching the system closely because its sluggish movement could prolong impacts once it arrives. Authorities may need to prepare cooling centers, public-health advisories, and wildfire precautions if the wave strengthens further.
