The state of Sonora is experiencing weather characterized by high temperatures and atmospheric instability. Early reports indicated that while Hermosillo faced clear skies with temperatures around 33°C, other regions could reach 40°C. The influence of Cold Front Number 1 introduced potential rainfall between 5 and 25 millimeters, alongside possible electrical activity or isolated hail. By October 4, forecasts maintained a mix of heat and scattered rain. Temperatures in the northwest, including San Luis Río Colorado and Heroica Caborca, were expected to reach 40°C, with wind gusts between 50 and 70 km/h. While the probability of rain in Hermosillo remained low, mountainous eastern and southeastern regions faced higher precipitation probabilities. Forecasts indicated a mid-week trend of increasing humidity and rising temperatures, with potential peaks of 42°C. As of October 6, the state is facing extreme heat, with Hermosillo expected to see temperatures between 39°C and 43°C throughout the week. San Luis Río Colorado and Caborca are forecasted to hit maximums of 41°C. Meteorological experts suggest a potential shift toward the weekend. The remnants of Hurricane Rachel combined with an approaching cold front may increase humidity and the possibility of rain. In Hermosillo, temperatures could drop to approximately 35°C or 36°C by Sunday or Monday, with a 24% to 40% chance of showers. Some areas may also experience wind gusts of up to 50 km/h.
