Mexico: Adverse winter weather forecast over northern and northwestern regions Jan. 11

Adverse winter weather is forecast across much of northern and northwestern Mexico Jan. 11. A cold front will move over the region, bringing showers, strong winds, and cold temperatures across parts of the affected area. Snowfall and sleet are possible in elevated areas of Baja California. Chihuahua, and Sonora states. Winds gusting over 100 kph (62 mph) are forecast in Chihuahua and Durango and over 80 kph (50 mph) across the rest of the affected area. Temperatures may reach below -10 C (14 F ) in elevated parts of the region early Jan. 11. Dust storms are possible in arid parts of the region.

Precipitation is forecast to fall as snow and sleet across mountainous parts of the affected regions over the coming days. Wind gusts could cause blowing and drifting snow; decreased visibility is likely in mountainous areas. Power outages could occur throughout the affected areas.

Flash and areal flooding are possible where precipitation falls as rain. Such flooding is particularly possible in low-lying communities near watercourses and other large bodies of water, as well as in urban areas with easily overwhelmed stormwater drainage systems. Sites located downstream of large reservoirs may be subject to flash flooding after relatively short periods of intense rainfall.

The adverse weather will likely cause ground and air transport disruptions in affected regions over the coming days. Traffic and commercial trucking delays are possible along regional highways. Difficult and potentially dangerous driving conditions are also likely on secondary and rural roadways in the affected regions as maintenance crews prioritize clearing major routes. Authorities could close stretches of highways if driving conditions become too hazardous. Gusty winds may threaten to topple high-profile vehicles. Flight delays and cancellations are likely due to ground stops and deicing operations at airports in affected regions.
