San Miguel el Alto — a Los Altos town known for cattle ranching — sees rain the way much of Jalisco does: driven by North American monsoon convective storms, intensified along the Pacific coast by hurricane moisture, arriving fast and unevenly.
One practical result: urban drainage failure over buried rivers and coastal storm flooding is something San Miguel el Alto deals with regularly, in line with the broader pattern seen across Jalisco.
