SMN warns of intense rains and drop in temperature in Mexico in the middle of the week

During Tuesday and Wednesday, General conditions will be marked by significant rains in the east, south and southeast of Mexicoincluding the Yucatán Peninsula. The heaviest rainfall will be concentrated in Veracruz and Oaxaca. This situation will be caused by several active atmospheric systems, including low pressure troughs, a high-altitude trough, moisture from the oceans, and cloud cover associated with a monsoon trough in the South Pacific. These conditions could lead to electric shocks, hail, landslides and flooding in low areas.

He Tuesday October 21a low pressure channel over the southeast, in interaction with a trough at altitude and cloudiness of the Pacific, will generate intense rains, especially in Oaxaca and Veracruz. In turn, a low pressure area with possible cyclonic development south of Guerrero will reinforce these rains. Another low pressure channel, this time over the interior of the country, will bring showers to the north, west and center. Furthermore, cold front no. 9 will enter through the northern border, causing intense winds and a drop in temperature in the northwest. Meanwhile, an anticyclonic circulation will reduce the probability of rain in the North Table and part of the center.

Regarding the distribution by region, intense rains are expected that Tuesday in Oaxaca and Veracruz, with very heavy rainfall in Puebla, Chiapas, Tabasco and Campeche. Guerrero, Yucatán and Quintana Roo will register heavy showers, while states such as Jalisco, Colima and Michoacán will see more dispersed rains. The wind will reach gusts of up to 70 km/h on the Isthmus of Tehuantepec and the waves will exceed 2 meters on the coasts of the southern Pacific and the Baja California peninsula. Maximum temperatures will remain high (35 to 40 °C) in the north and southeast, while minimum temperatures of up to -5 °C are expected in mountainous areas of the center and north.

For him Wednesday October 22weather systems will persist: the low pressure channel and the trough at altitude will continue to generate rain in the southeast and the Yucatan Peninsula. Additionally, tropical wave no. 39 will enter from Guatemala to the south of Chiapas, increasing humidity in the region. In the northwest, the combination of a mid- and upper-level trough with the subtropical jet stream will cause strong winds and further temperature drops. The northern and central region will maintain a low probability of rain thanks to an anticyclonic circulation.

During that day, the heaviest rains will continue in Veracruz, Oaxaca and Chiapas, with showers in Puebla, Tabasco, Campeche, Yucatán and Quintana Roo. Strong winds are forecast in the Isthmus of Tehuantepec and waves of up to 3 meters in the Pacific. Temperatures will continue in high ranges in most of the country, with minimums again below 0 °C in the northern and central mountain ranges.

between the Thursday 23 and the Saturday October 25the pattern of intense rains will continue in the south and southeast of the country due to the persistence of the low pressure channel and the monsoon trough. The tropical wave no. 39 will move off the coasts of the southern and central Pacific, bringing more humidity. In the north, an upper-level trough and a new cold front will bring rain and strong winds. An anticyclonic circulation that will move towards the Gulf of Mexico could increase humidity and the probability of rain in the center and northeast of the country.

On Thursday, very heavy rains will continue in Oaxaca and Veracruz, while Chiapas, Tabasco and Quintana Roo will have heavy showers. For Friday, the activity will move to the west and north, affecting states such as Jalisco, Michoacán, Guerrero and Coahuila. On Saturday, rain will repeat in those areas, while the north and center will have intermittent showers. Throughout the period, winds will continue with gusts of up to 60 km/h in the north and southeast, high waves on the Pacific coast, and extreme temperatures: maximums of 35 to 40 °C in the north and southeast, and minimums of -5 to 0 °C in the northern mountains and central highlands.

Finally, It is recommended to stay informed and take precautions against the probability of landslides, floods and hail due to intense rains.as well as damage from strong winds to light structures. This four-day period will be dominated by multiple weather systems that will continue to create adverse conditions across much of the country.
