Ola de calor en el oeste de EE. UU. rompe récords y evacua

Clima

La Oficina Nacional de Meteorología informó que la ola de calor que azotó el oeste de EE. UU. el 27 de julio de 2026 estableció récords de temperatura en varios estados y obligó a evacuar a residentes del noroeste del Pacífico, mientras las autoridades alertaron sobre riesgos de salud por el calor. Durante la semana anterior, los meteorólogos señalaron que un domo de calor desplazado elevó la temperatura en California por encima de 119 °F y generó alertas extremas para más de 42 millones de personas en el sur del país.

Los pronósticos indicaron que el domo aumentaría las temperaturas entre 10 y 20 °F sobre lo normal en todo el oeste, afectando a millones. La Oficina Nacional de Meteorología luego proyectó máximas de 115-120 °F en el suroeste y lecturas de tres cifras en el interior de California. Un sistema de alta presión impulsó temperaturas cercanas a los récords desde Arizona hasta Montana, provocando avisos de calor, mayor uso de centros de enfriamiento y un riesgo elevado de incendios. Al final del periodo, las advertencias de calor extremo cubrían aproximadamente a 55 millones de personas desde California hasta Montana.
