This Sunday, various climatic phenomena will interact in the atmosphere and will cause very heavy rains in eastern and southern Mexico.
The National Meteorological Service (SMN) reported that the most intense precipitations are expected in Veracruz, Tabasco, Chiapas, Oaxaca, Puebla and Quintana Roo. There, between 50 and 75 liters per square meter (l / m2) could fall, and severe gusts of wind are expected during storms.
Furthermore, in Puebla and Oaxaca strong punctual rains are forecast, ranging from 25 to 50 l / m2; Meanwhile in Nuevo León, Tamaulipas, San Luis Potosí, Campeche and Yucatán, accumulations of water of up to 25 l / m2 could be registered. Finally, in Coahuila, Querétaro, Hidalgo, Tlaxcala, Michoacán and Guerrero isolated showers are expected.
According to the climate body of the National Water Commission (Conagua), these precipitations will be accompanied by electric shocks, hail and strong gusts, and they could cause an increase in the levels of rivers and streams, landslides, and floods in low areas of the land.
The storms will be caused by the interaction of Tropical Wave Number 44, which is located on the Yucatan Peninsula, and a low pressure channel that extends over the Gulf of Mexico. To these phenomena will be added the entry of humidity from the Atlantic and Pacific oceans, favoring the potential for rainfall.
At the same time, a new cold front will enter the north of the country, causing gusts of wind of 60 to 70 km / h in Coahuila and Chihuahua. In this last entity, dust collectors could also be registered.
