Heavy and very heavy rains are reported in the south of the country for Chiapas, Oaxaca and Tabasco, while in Veracruz, Campeche, Yucatán and Quintana Roo showers will be recorded.
These conditions, according to the Conagua, are generated by the presence of Cold Front Number 26, which will extend over the Yucatan Peninsula and the southeast of the Mexican Republic, and by its cold air mass, which will be reinforced by the air mass that drives the Cold Front Number 28, in the process of dissipation.
