A severe heat wave gripping the northwestern state of Sonora is expected to push temperatures past 40 degrees Celsius (104 degrees Fahrenheit) for the next three days, with some areas potentially reaching 47 degrees Celsius. This extreme weather not only poses health risks but has already led to 22 fatalities and affected over 350 individuals, according to the Sonora state Health Ministry. Residents of cities like San Luis Río Colorado, Caborca, and Hermosillo should prepare for oppressive heat, particularly with the relative humidity hovering around 45% in Hermosillo, amplifying discomfort under an “extreme” ultraviolet radiation index.
As the National Meteorological Service continues to track these conditions, it also highlights the presence of summer monsoons that may bring isolated storms to the central and southern mountainous regions of Sonora. However, these storms will not alleviate the soaring temperatures. The State Civil Protection Coordination advises that while rainfall may be moderate to heavy, it’s essential for everyone, especially construction and agricultural workers, to exercise extreme caution. Employers are encouraged to allow for hydration breaks during peak sun hours to keep workers safe.
Health authorities are urging the public to stay hydrated, wear light-colored and lightweight clothing, and seek shade whenever possible. Older adults and children are particularly vulnerable, and residents are advised to avoid outdoor activities during the hottest part of the day. The signs of heatstroke can include severe headaches, confusion, nausea, and hot skin. If these symptoms arise, it’s crucial to seek medical attention immediately by calling 911.
