The National Meteorological Service (SMN) warns of severe heat, storms, and high seas in northern states for Tuesday, July 24. Temperatures may reach as high as 45°C (113 °F) in Baja California, Sonora, Chihuahua, Coahuila, Nuevo León, Sinaloa, Michoacán, Oaxaca, and Tamaulipas. Strong storms, with the possibility of hail, are expected in Sonora and Baja California Sur. High sea conditions, with waves up to 2-3 m (6-10 ft), are also anticipated along the Pacific coast from Chiapas to Sinaloa, as well as along the coast of Baja California Sur. Related travel disruptions, hazardous driving conditions, and power outages are possible.
These high temperatures could be hazardous to health, particularly for the elderly, young children, and people suffering from chronic illnesses such as cardiac issues, hypertension, and diabetes. Symptoms of heatstroke include high fever, hot, red, dry skin, headache, nausea, drowsiness, intense thirst, confusion, convulsions, and loss of consciousness.
A period of extremely high temperatures, known as the canícula, is common in Mexico during the summer months, although typically affecting the Yucatan Peninsula, the south, and southeastern regions are most impacted, according to the SMN.
Individuals in affected areas are advised to keep abreast of local weather forecasts, avoid strenuous outdoor activity, remain indoors as much as possible between noon and 16:00 when temperatures tend to peak, remain well hydrated (with sugar-free, non-alcoholic beverages), and wear loose, light-colored clothing. Do not hesitate to seek medical attention if displaying symptoms of heatstroke.
