During this night and the early morning of Friday April 19a combination of atmospheric systems is expected to generate adverse conditions in several regions of the country.
According to him National Metereological Servicethe anticyclonic circulation at middle levels of the atmosphere, associated with the heat wave, will prevail in the northwest, west and south of Mexico, maintaining a stable climate with a low probability of rain.
However, in contrast, in the north of the country, specifically in Coahuila, Nuevo León, Tamaulipas, San Luis Potosí, Querétaro, Hidalgo and Pueblaheavy occasional rains are expected, accompanied by electric shocks and possible hail.
The interaction of a dry line over northern Mexico with a low pressure channel in the center and east of the countryas well as a trough at medium and high levels of the atmosphere over the same northern region, will be responsible for these adverse weather conditions.
These precipitations could cause a increase in river and stream levelsas well as puddles, landslides and floods.
In addition to the rains, winds are expected strong with speeds of 60 to 70 km/hmainly in Coahuila, Nuevo León and Tamaulipas, with the possibility of formation of whirlwinds or tornadoes.
They are also expected wind gusts of 40 to 60 km/h in various areas of the country, from Baja California to Veracruz.
He entry of moisture from the Pacific Ocean, the Gulf of Mexico and the Caribbean Seawill contribute to the generation of rains and showers in other areas of the country such as Michoacán, Oaxaca, Chiapas and Quintana Roo, with the possibility of winds of 40 to 60 km/h in Tabasco, Campeche, Yucatán and Quintana Roo.
For the next day, high temperatures expected to persistwith maximum temperatures that could exceed 45 °C in some areas, while in the north and northeast, low pressure channels could maintain conditions conducive to rain and possible tornadoes in Coahuila, Nuevo León and Tamaulipasas well as in the east and center of the country.
